Cape Fur Seal: Roaring Personalities in a Double Coat

The Cape Fur Seal isn’t your average beach bum. These boisterous pinnipeds boast a combination of physical adaptations and social behaviours that make them stand out on the South African coast. Here’s what makes them special:

• Dressed for Success: Unlike most seals, Cape Fur Seals have a luxurious double coat. The soft underfur keeps them warm in the chilly waters, while the bristly outer coat acts like a waterproof shield. This impressive insulation allows them to thrive in the Benguela Current, a cold ocean stream that sweeps up the African coast.
• Size Matters: These are some of the biggest fur seals around. Males, easily identified by their mane of fur, can reach lengths of 2.3 meters (8 feet) and tip the scales at a hefty 350 kg (770 lbs). This impressive size makes them formidable predators and dominant figures within their colonies.
• Vocal Virtuosos: Forget barking dogs – Cape Fur Seals are the real chatterboxes of the beach. With a complex repertoire of barks, growls, and bellows, they communicate everything from threats and greetings to attracting mates and keeping track of their pups. These vocalizations are surprisingly unique, allowing mothers to identify their pups even after days at sea.
• Built for the Deep: Streamlined bodies and powerful flippers make Cape Fur Seals masters of the underwater world. They can dive to depths exceeding 100 meters (330 feet) in search of prey, using their keen eyesight and long whiskers to navigate the kelp forests and rocky reefs.
• Social Butterflies (… with teeth): Cape Fur Seals are highly social animals, forming massive colonies that can number in the tens of thousands. While they can be playful and even cooperative, their social interactions are often marked by competition. Males fiercely defend territories and vie for mates, creating a dynamic and sometimes raucous atmosphere on the beach.

These are just a few of the unique traits that make Cape Fur Seals such fascinating creatures. From their impressive double coat to their boisterous social lives, they are a vital part of the South African coastal ecosystem

Cape Fur Seal: Lords of the Rocky Shores

The Cape Fur Seal isn’t just a beach bum; it’s a strategic resident with a preference for prime real estate. Here’s a closer look at their chosen habitat and the intriguing behaviours that unfold within it:

Rocky Realms of The Cape Fur Seal: Unlike some seals that favour ice floes, Cape Fur Seals are all about the rocky shores. They thrive along the coastlines of Namibia and South Africa, where rocky outcrops, islands, and boulder beaches provide the perfect platform for hauling out, breeding, and basking in the sun. These rocky havens offer several advantages:

• Defence Against Predators: The jumbled terrain makes it difficult for land-based predators like jackals and hyenas to snatch pups.
• High Dive Sites: Rocky cliffs provide excellent launching points for their impressive dives into the ocean depths.
• Sunbathing Spots: Flat, sun-drenched rocks are ideal for pups to thermoregulate and adult seals to molt their thick coats.

Life on the Rocks: These colonies are a hive of activity, with distinct social dynamics at play:

• Segregated Shores: The prime real estate is fiercely contested. Dominant males claim territories closest to the water’s edge, attracting females with impressive displays and vocalizations. Females, in turn, compete for prime birthing spots within these territories.
• Cooperative Hunting: While not as social in the water, Cape Fur Seals sometimes form loose hunting groups. These temporary partnerships help them locate and capture shoals of fish, their main prey.
• Pups with Personality: From the moment they’re born, Cape Fur Seal pups are surprisingly independent. They learn to swim within weeks and are weaned around 4-6 months, though some may nurse for much longer. Their playful nature often leads to adorable wrestling matches and mock charges on the beach, showcasing their developing hunting skills.

Beyond the Beach: Though primarily land dwellers for breeding and molting, Cape Fur Seals are incredibly adapted for life at sea:

• Deep-Sea Divers: Boasting streamlined bodies and powerful flippers, they can hold their breath for up to 7.5 minutes and dive to depths exceeding 100 meters. Their sensitive whiskers help them navigate the ocean depths and locate prey.
• Acrobatic Hunters: Agile and graceful in the water, they’re known for their impressive dives and twists as they chase fish. This agility allows them to access prey that other marine predators might miss.

The Cape Fur Seal’s combination of a strategic habitat choice and intriguing social behaviours makes them a captivating addition to the South African coastline. From their playful antics on land to their impressive hunting prowess in the ocean, they are a true testament to the wonders of adaptation and the dynamic nature of life at sea.

Cape Fur Seal: Masters of the Menu at Sea

The Cape Fur Seal isn’t just a sunbather; it’s a cunning predator with a discerning palate. Here’s a dive into their diet and hunting habits, revealing their role as both beneficiary and influencer in the Southern African marine ecosystem:

Seafood Smorgasbord: These opportunistic eaters are carnivores, with a menu that changes depending on the season and prey availability. However, their primary course is all about the fish:

• Shoal Specialists: Cape Fur Seals are adept at hunting schooling fish like sardines, anchovies, and mackerel. Their keen eyesight allows them to spot shimmering patches of fish from above, and their powerful flippers propel them through the water at impressive speeds. Once a shoal is located, the hunt turns into a feeding frenzy, with multiple seals working together to herd and overwhelm their prey.
• Beyond the Basics: While fish form the mainstay of their diet, Cape Fur Seals are not picky eaters. They also enjoy a variety of other marine delicacies, including:
  • Squid: These slippery morsels are a tasty snack, often snatched up during dives.
  • Octopus: Their strong jaws and sharp teeth allow them to tackle these more challenging prey.
  • Crustaceans: Crabs and lobsters are a welcome addition to their diet, adding variety and nutrients.
  • Birds on Occasion: Seabirds like penguins can become a target if the opportunity arises, although this is less common.

Fascinating Foodie Facts: Here are some quirky aspects of the Cape Fur Seal’s culinary adventures:

• Deep-Sea Dining: Their impressive diving abilities allow them to access prey in deeper waters, where competition is less fierce. This not only benefits them but helps maintain healthy fish populations closer to the surface.
• Selective Tastes: While they’re not above scavenging, Cape Fur Seals seem to have a preference for fresh fish. They’ve been observed discarding fish that appear diseased or injured.
• Waste Not, Want Not: These efficient eaters don’t waste a thing. They consume most of their prey whole, minimizing waste and maximizing their energy intake.

From their preference for fresh fish to their deep-sea dining, these charismatic creatures are as fascinating for their culinary prowess as they are for their social lives and playful antics.

Cape Fur Seals: Masters of Maternal Multitasking

The Cape Fur Seal colony might seem like a chaotic jumble of barking bodies, but beneath the surface lies a fascinating strategy for ensuring the next generation. Here’s a look at their unique reproductive cycle:

Masters of Delayed Implantation: Unlike many mammals, Cape Fur Seals utilise a clever trick called delayed implantation. After mating, the fertilized egg doesn’t immediately implant itself in the uterus. Instead, it enters a state of dormancy for several months. This allows the mother to focus on nursing her current pup without the additional energetic burden of pregnancy.

Gestation on the Go: Once the current pup is weaned, typically around 4-6 months old, the dormant embryo finally implants in the uterus and begins development. This allows for a one-year gap between mating and pup birth, ensuring the mother has sufficient time to recover and gather resources for raising her newborn.

Newborn Nuggets: Pups arrive between November and December, typically weighing around 6kg (13 lbs) and sporting a thick layer of lanugo, a soft, woolly coat that provides warmth until their adult fur grows in. These adorable balls of fluff are precocious, learning to swim within weeks and becoming independent hunters within a few months.

Mothers on a Mission: Female Cape Fur Seals are dedicated mothers. They nurse their pups for an extended period, sometimes as long as 11 months. This extended nursing period allows for the transfer of essential antibodies and nutrients, crucial for the pup’s survival in the harsh ocean environment.

Balancing Act: However, Cape Fur Seal mothers are also masters of multitasking. While nursing their pups on land, they embark on regular foraging trips at sea, sometimes lasting several days. This allows them to replenish their energy reserves to continue providing for their offspring.

Contribution to Population Continuity: This carefully timed reproductive cycle ensures the survival and growth of the Cape Fur Seal population:

• Year-Round Breeding: With females giving birth annually, there’s a constant stream of new pups entering the colony.
• Extended Nursing: The lengthy nursing period gives pups the best chance of survival, leading to a higher population growth rate.
• Delayed Implantation: This clever adaptation ensures the mother is in optimal physical condition to raise both her current and future pup.

The Cape Fur Seal’s reproductive strategies are a marvel of adaptation, showcasing their ability to maximize offspring survival and ensure the continued success of their species. From the timing of implantation to the mothers’ dedication, these charismatic creatures exhibit an impressive investment in the future generations that will populate the South African coastline.

Understanding Bronze Whaler Sharks

Bronze whaler sharks, (copper sharks or narrow tooth sharks), are fascinating creatures that inhabit the world’s oceans. With their distinctive appearance and impressive size, they capture the attention of marine enthusiasts and researchers alike. We are going to look at many aspects of what makes up the Bronze Whaler Shark, starting with the taxonomy and physical features, geographic distribution, as well as the size and lifespan of bronze whaler sharks.

Taxonomy and Physical Features

Bronze whaler sharks belong to the family Carcharhinidae, which includes a diverse group of requiem sharks. Their scientific name, Carcharhinus brachyurus, reflects their classification within the genus Carcharhinus. These sharks possess a streamlined body shape, a characteristic of pelagic species, allowing them to move swiftly through the water.

One of the distinguishing features of bronze whaler sharks is their bronze or copper-coloured dorsal side, which gives them their common name. Their belly is typically white, enhancing their camouflage from both above and below. They have a broad, rounded snout and relatively large eyes, providing excellent vision in low-light conditions. Their upper jaw contains several rows of sharp, serrated teeth, allowing them to efficiently capture and consume their prey.

Geographic Distribution

Bronze whaler sharks are found in temperate and tropical waters worldwide. They have a broad geographic distribution, inhabiting coastal regions of the Atlantic, Indian, and Pacific Oceans. These sharks are known to frequent continental shelves and slopes, as well as offshore islands. However, they are most commonly encountered in areas with abundant food sources, such as seals, sea lions, and various fish species.

Insights into the Behaviour and Reproduction of the Bronze Whaler Sharks

Bronze Whaler Sharks are fascinating creatures when it comes to their social behaviour and reproduction. Let us now explore their group dynamics, social hierarchies, mating rituals, and the intriguing processes of gestation and birth.

Group Dynamics and Social Hierarchies

Bronze Whaler Sharks exhibit a unique social structure, often forming loose aggregations or schools that can vary in size. These schools consist of individuals of various ages and sizes. Within these groups, social hierarchies may emerge, where larger and more dominant sharks tend to occupy higher positions.

The establishment of social hierarchies helps maintain order within the group and can influence feeding patterns and access to resources. Dominant individuals often have preferential access to food sources and mating opportunities. Social interactions such as displays of dominance, body posturing, and occasional aggression contribute to the establishment and maintenance of these hierarchies.

Mating and Courtship Rituals

During the mating season, male Bronze Whaler Sharks actively pursue females in a process known as courtship. Courtship rituals typically involve intricate behaviours, including swimming patterns, biting, and nipping, to establish the male’s suitability as a mate.

Males may engage in competitive displays to gain the attention and acceptance of receptive females. These displays often involve rapid swimming, biting each other’s pectoral fins, and showing off their physical attributes. Females play a more passive role, selecting a suitable mate based on these courtship displays and the dominance status of the males.

Gestation and Birth

After successful mating, female Bronze Whaler Sharks undergo a period of gestation before giving birth to live young. The gestation period can vary between 12 to 16 months, depending on environmental conditions and the availability of food resources. During this time, the embryos develop within the female’s body, nourished by a specialized structure called a yolk sac placenta.

Once the gestation period is complete, the female gives birth to a litter of fully formed pups, typically numbering between 12 to 20 individuals. The pups are born in shallow nursery areas where they find protection from potential predators and have access to abundant food sources. These nurseries serve as crucial habitats for the initial stages of the pups’ lives, allowing them to grow and develop before venturing into open waters.

Bronze Whaler Sharks exhibit fascinating social behaviour and reproductive strategies, showcasing the complexity of their lives beyond their predatory nature. Their group dynamics and social hierarchies contribute to the organization and stability of their communities. Mating rituals and courtship displays play a significant role in ensuring successful reproduction, while the process of gestation and birth ensures the survival and continuation of the species.

Simons town is a picturesque and historical town, steeped in naval history and situated in False bay only 40 minutes from the central Cape Town CBD district. This quaint little village has a rich history, from the first four-legged able seaman to Shark Cage dives around the famous Seal Island. Simons Town is made up of a number of varying restaurants and museums, to cater to a variety of pallets and is well known for being South Africa’s largest naval base. On Jubilee square you will find the statue of a Great Dane, the most famous dog in SA naval history, Just Nuisance. 

Seaforth Beach, just before the world famous Boulders Beach, in Simons town offers you the unique experience of being able to pose with the South African Jackass penguin and then, just a short walk along the penguin walkway will take you to Boulders Beach, where you are able to, from a distance, interact and watch these gorgeous little tuxedo’s gents doing what gorgeous little tuxedo gents do. If you are looking to swim in the same waters as the Jackass, then take a couple steps back towards Seaforth Beach, but some good advice; do not try to touch, feed or physically interact with them in any way. Remember, they are wild animals and have been known to bite and nip quite painfully! Since 1985 these waddling little guys in their black and white suites have made a home and settled between the granite boulders which shelter the beach from weather and sea conditions, hence the name Boulders beach. To date the population of penguins at this colony is estimated at up to 3000 birds. Simons Town has it’s very own “March of the penguins” every evening at around 18h00, when these African Penguins make their way, to their various nests and sleeping holes for the night, and their donkey-like squawks can be heard far and wide.

Boulders and its many surrounding breath-taking beaches form part of the Table Mountain National Park Marine Protected area ensuring the safety of the beach and protection of the African penguin who like so many animals have been classified as an endangered species. Boardwalks and walkways were created to provide great viewing spots and access to the beach for the many tourists who annually visit this spectacular area. These are also a means of protecting nesting penguins and chicks from human intervention.

Seal island, our dive site, a colony of between 65000-75000 Cape fur seals, has a small population of African penguins. These birds have been provided with artificial nests and this has greatly increased their breeding success over the years. It is estimated that around 80 pairs of penguins breed each year.

Cape point nature reserve is a majestic and spectacular sight with its miles and miles of indigenous fynbos, towering cliffs and roaring ocean. It is often referred to as the point where the Atlantic and Indian oceans meet. This is however a mistaken perception, as it is, the south-western most point of Africa, not the southern- most.

With its natural indigenous beauty, fauna, flora, framework of mountains and ocean, Cape point is one of Cape town’s most popular tourist destinations. It is a wonderful day-trip destination for locals and tourists. Whether it’s discovering the rich history of the area, enjoying a beach walk or swim in the tidal pools, or simply relishing time under the African sun, there is bound to be something for the whole family.

Animal lovers should keep a vigilant eye out for local baboons, herds of ostriches, a variety of antelope as well as Cape foxes, genets, polecats, mole rats, porcupines, mongooses, tortoises, zebra and snakes. The reserve is also home to over 270 species of birds which makes for excellent bird watching all year round.

One of the reserves places of interest is, Cape point’s first lighthouse. The structure was built in 1859 and instead of guiding ships to safety it was often the cause of many wrecks, reason being that the lighthouse is often concealed by clouds, as it is towers high above the ocean and therefore ships would see the bright lights too noticeably and approach the shore to prematurely.

The Olifantsbos trail, is another prevalent prospect. It is a short and easily accessible walk which leads down to the beach through fynbos foliage where the prominent SS Thomas T. Tucker, wrecked in 1942, lies. This former WWII troops and weapons transport vessel is Cape Point’s most photographed shipwreck and is home to many native birdlife

It is quite evident that the False bay area has much to offer and is a definite must-see when in Cape Town. So, why not opt for a package deal! Book a cage dive and Cape Point tour, visit our beautiful African Penguins and sight-see the majestic Cape Point.

We would love to have you join us on one of our cage dives in Simons town, but if this is not possible let’s help arrange it for you elsewhere.

Let’s try to understand the misunderstood.

Despite the importance of the biological diversity in the world’s oceans, and the well balanced community of species, with the over fishing, illegal fishing and poaching of the oceans resources as well as climate changes and the steady destruction of marine habitats, the Marine eco-systems are becoming increasingly unstable.

Every eco-system plays a vital role; one of the most important functions of the marine eco-systems is the production of biomass from sunlight and nutrients, which represents the basic food course for all marine life, and so ultimately human also. Around half of the worlds’ primary productivity is achieved by microscopically small plants, and phytoplankton, which grow and divide in the ocean.

Another function performed by ecosystems is the creation of habitats in coastal ecosystems…

For example, macro algae, seagrass and corals form large undersea forests, meadows or reefs that provide habitats for many other species such as molluscs, crustaceans and fish. Kelp forests and seagrass meadows in the Baltic Sea are vital habitats for the fry and juvenile fish that grow up here before swimming into the open ocean as adults. As with mangroves and the Lemon Shark. Gastropods and small crustaceans likewise feed on microalgae growing on the kelp or seagrass. They thereby ensure that the structure-forming plants are not smothered, and are allowed to grow – that is their contribution to the ecosystem. The molluscs and crustaceans that feed on microalgae are the basic food source for larger predatory crustaceans and fish.

Seagrass and kelp itself have relatively long life spans because they are poor food sources for grazing crustaceans and molluscs. They store nutrients in their biomass for a long time, including nitrogen and phosphorous compounds transported by rivers from agricultural areas to the sea. Seagrass and macroalgae thus function as a kind of biological purification system in coastal ecosystems.

Biological diversity in the oceans is essential.

There has been a lot of study and research around the dramatic decline in biological diversity and whether it has consequences for the stable functioning of eco-systems and after 10 years of intensive study, the answer is a resounding “yes, it most certainly does!” Experiments in coastal eco-systems, particularly seagrass meadows and kelp forests, have shown that biological diversity in the oceans is essential for maintaining the eco-system. Species diversity was decreased in various ways during these experiments in order to compare the eco-system functions of species-rich with species-poor areas. In one field experiment, for example, the number of seaweed species was artificially reduced by removing some at the beginning of the growth period. The total algal biomass in this species-poor area did, in fact, decrease, thereby resulting in a decline in the food for consumers as well as the number of available habitats. In another experiment, the number of grazing species that feed on the microalgae growing on seagrass was reduced. It was found that the species-poor grazer communities consumed fewer microalgae than species-rich communities. The shortage of grazing species resulted in a slower growth of seagrass because the increased growth of microalgae repressed photosynthesis in the seagrass. These two experiments indicate that a decrease in biological diversity has a negative impact on the structure of the habitat, regardless of whether the number of species of producers (macroalgae) or consumers (grazers) is reduced.

Till we meet again, keep that toothy grin!

Seeing sharks close by gives me butterflies in my stomach (wait… that’s love?), okay then they make my stomach growl (nope, that’s when I’m hungry)… Oh, I got it! Sharks turn my stomach inside out. No! They turn their own stomachs inside out… They can’t actually vomit instead they do something similar to vomiting: gastric eversion. This is where the stomach relaxes and oesophagus contracts to “clean” any indigestible food like licence plates, parasites or bones from the stomach lining.

Let’s take a look at how a shark digests its lovely not broken seal prey.

The digestive system can be separated into four sections: the oral cavity; the foregut; midgut and the hindgut.

1. The Oral Cavity

The oral cavity is basically the mouth section consists of those lovely pearly whites, mouth, and pharynx. Here there are no digestive juices secreted, as the shark does not chew his food so the food does not need to be digested for swallowing.

2. Foregut

The foregut is composed of the oesophagus and stomach.

The oesophagus the oral cavity, i.e. the mouth and pharynx to the stomach. This stops the food from exiting the mouth as they have striated muscles to stretch to the size of the prey for swallowing. Imagine a seal being swallowed and not able swim to out… Yikes! The oesophagus looks like thousands of extended fingers.

The second half of the foregut is the stomach (hmmm yummy, yummy, yummy I got love in my tummy!). This is where the food is stored and digestion happens. So, strong stomach acids and enzymes such as gastric acid and pepsinogen are used to digest the food.

*Interesting fact*: Their stomachs are U-shaped!

The foregut and midgut are connected by a small control device called the pyloric valve. Only mush is pushed through there because the stomach acid dissolves the stomach contents.

3. The Midgut

The midgut is composed of two sections, the small intestine, and large intestine.

T small intestine has the duodenum and ileum – which is similar to a human but the large intestine is actually shaped like a screw. It is twisted in this shape, as there is more surface area to aid in absorption and increase digestion. Most of the nutrients are absorbed in the midgut.

4. The Hindgut

The hindgut is where all the poopie comes out. Like a mullet, its business in the front and party in the back.

The large intestine is connected to the colon as a continuation of the small intestine. This is then connected to the rectum and cloaca that collects waste from the colon and the rest is “history”

Honestly, I don’t think I can “stomach” picturing this “gut” reaction.

With all the “boo-ha-ha” in Gansbaai, regarding the appearance of 4 Orcas in the bay, which seemed to coincide with the disappearance of the Great White Shark population from the famous Shark Alley, I thought I would take a deeper look into this phenomenon, of course only once the sharks had returned.

There seems to be differing beliefs here, some on the side of the Orca, saying they are not responsible for the disappearance of the Great Whites, as they are not a threat and others who believe they are a threat and the sole reason for the Great White Shark’s game of hide and go seek.

There are arguments to back both schools of thought.

Both sides have a fair argument and both have proof to back up their claims. In False Bay in 2014, ASEC had many successful trips, filled with plenty shark activity out at Seal Island, and the trips were filled with so many of the oceans beautiful creatures, including dolphins, whales and the infamous orca! On the 35 minute boat ride from the Simons Town Pier to Seal Island, there were pods of 3 to 5 orcas swimming alongside the boat, playing in the wake with the dolphins. And on arrival at Seal Island, the Great White’s came out in pretty decent numbers to play, and proved active and engaging, with no apparent fear of the visiting orcas.

In 2016, we had another pod of Orcas visit our False Bay, and we found, what is believed to be evidence of Orca attacks on Seven Gill Cow Sharks, which as a result, scattered these sharks for well over 3 months!

Then there is video evidence of orca hunting on a Great White Shark, using its superior intelligence and strength to over power and kill the shark! It seems that certain cultures of Orca, have learnt how to make a meal of the previously believed, apex predator of the ocean!

Orcas only eat the liver of sharks.

This has led to the belief that there are different cultures within the Orca population; four have been identified to date, and one of them is the Great White Shark hunting and eating “culture”. When I say “eating” I don’t mean teeth, fins and all, but rather just the liver of the shark.

So it looks like both side of the coin hold truth, and it just depends on which of the Orca cultures come to visit at any given time. This also gives new meaning to the Apex Predator of the oceans, as an Orca, with its incredible strength and intelligence, is without a doubt a force to be reckoned with and a formidable foe, should he be one!

Join us in False Bay, for one of our amazing combination breaching, viewing and cage dive adventures, and may be you too will be blessed with the glorious sight of Orcas visiting our bay.

The Sandbar Shark is found in temperate and tropical waters, from the Western Atlantic, between Massachusetts and southern Brazil; in the eastern Atlantic from Portugal to Zaire; and in the Indo-Pacific from South Africa, our very own False Bay and KZN to the Galapagos and from Vietnam to New Caledonia. Also occurring in the Red Sea and Mediterranean, this shark is gorgeous. Not taking anything away from the others, but this little guy is just a stocky, solid shark, makes me think of a Staffie.

The Sandbar shark has cat-like eyes and a lovely smile.

He gets his name from being blue-greyish brown in colour with a paler underside, as with most sharks. He grows to a maximum of 2.4 meters (240 centimetres or 94 inches) and has a large dorsal fin for its body! He has almost cat-like eyes, and a lovely smile. His skin is thick and tough, which sadly makes it a wanted commodity in the leather industry, as well as its meat being used for human consumption and its fins for shark fin soup. This little guy was fished uncontrollably up until 1993, when the US placed restrictions on size, but still it is considered vulnerable! And will take many decades before it is no longer at threat of being made extinct!

The Sandbar Shark is classified as Vulnerable (VU) on the IUCN Red List, can we do something to change this?

The Sandbar Sharks’ nursery areas are filled with nutrients for the growth of the juvenile sharks.

The female Sandbar Shark gives birth to a litter of pups, varying in numbers between 1 and 14 pups, according to her size, the bigger she is the more pups she has. After a gestation period of between 8 to 12 months, she will move into shallow coastal areas to give birth, and then she will leave these nursery areas to return to their preferred 20 to 60 meters depth, near the oceans bottom. The juvenile Sandbar Sharks will remain in these nutrient filled nursery areas until winter, when they too will move out to the oceans depths.

The sexual maturity of a Sandbar Shark is between 12 and 15 years, adding to conservation concerns.

Females only give birth every second year at most, so the sharks slow growth and rate of sexual maturity, is a concern within its conservation status. Only reaching sexual maturity at between 12 and 15 years, and then reproducing between 1 and 14 pups every 2 to 4 years, it’s not possible for them to stay ahead of the fishing industry.

Though they have sharp triangular teeth, these sharks are not a threat to humans at all, enjoying a diet of small bottom feeding fish, crustaceans and molluscs, while the juveniles feast on blue crab.

Come and see Great Whites in their natural environment, as they fly through the air and develop a love for these and other fantastic sea creatures, within the waters of False Bay and the world!

Spotted Ragged Tooth Shark, the name alone creates a vision of some scary teeth, while Grey Nurse Shark, seems to send thoughts completely in the opposite direction, and Sand Tiger Shark, is kind of just in the middle there, and yet, all of these names belong to one shark! One shark that is found from Australia to the US and False Bay to Durban!

The Spotted Ragged Tooth enjoys the temperate to tropical coastal waters of the Atlantic, Indian and Pacific Oceans. In South Africa, they really love the Eastern and Southern coasts.

These beautiful sharks, grow to approximately 3.3 meters in length, with a rather wide girth and small dorsal fin, it’s pretty easy to distinguish. Besides, it has spots! The shark is a beautiful beige, almost golden colour with darker brown spots along its torso, and as with other sharks, it boasts a white or paler under-belly.

Spotted Ragged Tooth Sharks are ovoviviparous.

Being ovoviviparous, which means the embryo hatches from the egg inside the uterus, where it feeds off its own yolk sac until it is born the females will birth two pups after a 9 to 12 month gestation period, and most often, only every two years.

Spotted Ragged Tooth’s reach sexual maturity around 5 years of age or 2.2 meters and live to about 30 years, if not fished or killed! Mating is a vicious state of affairs, and often times you will see severely scarred female of the species, as the males have to “take hole” and the only way they are able to do that, is with those scary ragged teeth of theirs! So In November/December they get together to mate on reefs in northern Eastern Cape and southern KwaZulu-Natal waters. The pregnant females then travel north as far as southern Mozambique to gestate in warmer waters. Then once the gestation period of 9 to 12 months is over, they return to the Eastern Cape (south of the Kei River) to give birth.

The teeth are arranged in rows, from back to front, and continually push forward, a little like a conveyer belt, pushing out the blunter of the teeth, while newer, sharper and stronger teeth are produced, keeping the Spotted Ragged Tooth in ample supply of sharp teeth. These sharks lose thousands of teeth in their lifetime! So when you see a “shark tooth” necklace, it is more than likely a Ragger’s, and no, there is not some brave or stupid dentist who pulls them out.

Threatened Status.

The Spotted Ragged Tooth’s conservation status is threatened, from Australia to the US and in South Africa, and this is due to its slow sexual maturity and once every two year birth of possibly two pups. They have inshore habits, which make them vulnerable to the threat of humans, fishing them for sport. So much so, that in 1984 the Spotted Ragged Tooth, or Grey Nurse Shark, as known by the Australians, was named the world’s first ever protected shark species in Australia!

Found in False Bay, amongst other areas in the Western Cape through to Angola, this shark is a species of catshark! What? Catshark, really? Yes, really and not because it looks like this!

It is also known as a “Happy Eddie” but that is easier to explain, as its scientific name is Haploblepharus Edwardsii, you can see how that came to pass right?

A Shark growing to a maximum of 60cm…cute.

A small shark, growing to a maximum of 60cm in length (24 inches), it can be found at depth of up to 130 meters (426 feet) in rocky bottoms or habitats. It is slender with a flattened body and head and covered in little white spots all over its back. Various hues of brown are patched onto its little body. Not to be confused with the Natal Shyshark, or “Happy Kitty” as it is sometimes referred to … Haploblepharus

Kistnasamyi, get it? These two species differ in appearance and their preference of living areas.

Another reason for the name “Shyshark” is because when this little fella feels threatened, it will curl itself up, into a circle covering its eyes with its tail explaining the name given by local fisherman of “Doughnut”. It does this for obvious reasons; one of them being that this shape is a little more difficult for its predators to swallow. You may ask, what feeds on this little guy, well larger sharks and fish for one, and even the Cape Fur Seal will play a game of toss with him, which can and sadly does often result in the death of the Puffadder Shyshark, even though the seals do not eat the shark. Often in the pursuit of “fun” the seal will pull flesh from the shark, which then feeds the various pelagic birds.

When this little guy is not being used as a ball by seals, it will feed on crustaceans, segmented worms and smaller bony fish.

Not having any specific breeding season, the female will attach egg sacks, as they are oviparous, onto underwater, vertical structures, such as sea-fans. These egg casings are smaller than those of other shyshark species, measuring up to a maximum of 5cm long and 3cm across, as well as being thin walled and slightly furry to the touch, with long adhesive tendrils at the corners. The juvenile shark will hatch after 3 months and measure all of 9cm (3.5 in). They reach maturity at 35 to 55 cm (14 to 22 in) which works out to about 7 years of age, within their lifespan of 22 years.

The Puffadder Shyshark is not a threat to humans.

As you can imagine the Puffadder Shyshark is not a threat to humans, but according to the International Union for Conservation of Nature it is considered Near Threatened. It is not really fished specifically for food or anything other than to populate aquariums, but populates highly fished areas, so is often caught in “trek-nets”. Although still abundant, this shark lies entirely within a heavily fished region, and any increase in fishing activities or habitat degradation could potentially impact the entire population. Can we do anything to stop that from happening?

If you want to face a larger version of shark, you know, be eye to eye with a Great White Shark, then we’d love you to come and join us, book your once in a lifetime adventure with us!

Mako Sharks can reach and exceed 60 miles per hour.

As is the fact of the Longfin Mako, the Shortfin Mako is also exceptionally fast, the cheetah of the ocean if you will, reaching and surpassing 97 kph (60 mph) for extended periods of time.

Sometimes confused for a smaller version of the Great White Shark, a major identifying factor, are its scary razor sharp and strange looking teeth, which even when the Mako closes its mouth, are still visible! And even though “Flash Gordon” of the seven seas, looks scary, with those teeth, there are no records of any human bites or fatalities caused by the Shortfin Mako. In False Bay, we offer free diving with the Shortfin Mako, so if you have your open water dive certificate, and are able to keep up, you should book dive. Otherwise, book a cage dive and see the Great Whites in action from the safety of our boat and secure cage.

The Longfin Mako, has been recorded as having bitten humans, but only as a result of being caught in nets or on fishing lines, so only in self-defence, and never fatally. As with all of nature, these beautiful creatures are threatened by humans, fished for sport, their skin, fins and teeth, these animals are considered threatened. Again, is there anything we can do to change this status?

The Mako shark is the fastest swimming shark in the world at 40 kilometres per hour, attaining burst speeds up to 70 kilometres per hour. Most individuals are between 1.5 and 2.5 metres in length but large females up to 4 metres have been previously recorded. This species is found in temperate and tropical (17-22 degree Celsius) waters up to 500 metres in depth. These sharks, like white sharks, are adapted to life in these cool waters and have a heat exchange system in their body that keeps their muscles and internal temperature above that of the surrounding cool waters. This adaptation allows these sharks to maintain a high degree of activity.

These sharks are top predators that prey on various fish species as well as sea turtles, dolphins and occasionally marine debris.  Females are slow maturing at approximately 19 years, while males mature much sooner, at 8 years. Between 4 and 25 pups are typically born and at birth they are about 2 feet (60 cm) in length. Similar to great white shark pups, once born these baby sharks are left to fend to for themselves.

During the summer months when the white sharks have moved inshore, African Shark Eco-charters switches to running pelagic diving trips where you could be lucky enough to cage dive with blue and mako sharks in the blue waters 20 -40 nautical miles off Cape Point. On these trips you may also be lucky enough to see some offshore whale and dolphin species such as sperm whales, killer whales, pilot whales and risso’s dolphins and pelagic bird species.

The Mako’s breach much like the Great White Sharks do.

Much like the Great White, both Long and Shortfin Makos are known to breach (burst through the water into the air) but unlike the Great White, it is not a hundred percent known why the Makos do it, whether it’s for the “scouting” of food within its immediate area, or to rid itself of parasites, there is no confirmed explanation for this, but whatever the reason, it remains an awe inspiring and incredible sight, if lucky enough to witness it!

The Shortfin Mako, lives between 25 and 35 years, with the females aging faster than the males. Also, interestingly enough, as with other sharks, the recorded lifespans of the Mako, seem to be extended from years ago, could this be nature’s way of fighting against extinction?
