The Cape Fur Seal

The Cape Fur Seal is often referred to as the ‘dog of the ocean’. They are possibly the most curious and playful mammals you will ever have the joy of interacting with in their natural environment. Spinning and twirling in shoals of tiny, pearl-like bubbles, gazing at you with those gigantic shiny eyes, they will welcome you into their playground. And maybe even invite you to join in a game.

Fascinating Facts...

Before zipping-up your wetsuit, strapping on your goggles and diving right in, here are a few fascinating facts to keep in mind about these magical creatures:

The Cape Fur Seal is endemic to Southern Africa.

They are found as far north as the southern tip of Angola, with colonies occurring all along the coastlines of Namibia and South Africa, up to Algoa Bay near Port Elizabeth.

Population Size

According to the most recent estimations, roughly 2 million Cape Fur Seals reside in this range. Living in large colonies, the vast majority have settled along the pristine and wild beaches of southern Namibia as well as on islands just off the West Coast of South Africa. Since they are not nearly as agile on land as they are in the water, these secluded locations offer protection from human interference, land-based predators and habitat destruction.


Once they’ve reached adulthood, males are normally much larger than females, weighing up to 350kg. Females typically weigh in at around 80kg but can grow up to 150kg.


Within colonies you will find that males who have reached sexual maturity will gather a harem of females. Depending on the size of the colony, these harems can be as large as 50+ females at a time.

Delayed Pups!

Females are able to delay fertilisation for up to three months, in order to ensure that they will only give birth to pups at the beginning of summer – normally late November/early December. These pups are born without blubber and are unable to swim, making them highly dependent on their mothers for nutrition and protection.
It usually takes about three months for seal pups to make their way into the water and swim confidently on their own. The best time of year to witness this cute clumsiness is at the beginning of March. Seal pups are easy to spot, as they are much tinier than the rest of the colony. They also have darker fur, appearing pitch black underwater.

Food… yum yum

While pups are suckled for the first few weeks of their lives, they eventually have to join their parents and older siblings in the hunt for food. Cape Fur Seals are traditionally most fond of pilchards and anchovies. However, since the numbers of these fish have been dwindling, mostly due to overfishing, seals have had to look for alternative sources of food. Fortunately, they are rather opportunistic and highly adaptable, happily snacking on anything from crayfish and shrimps to seagulls and penguins.


While Cape Fur Seals seem to have tiny eyes on land, they pop wide open under water, taking on something of a torch-like look. With the ability to dive to a depth of up to 200m, their intensely-developed eyes help them to see in even the murkiest conditions.

Fur Coats

Fur seals are so called, because they have two thick layers of fur – a soft inner layer and a more bristly outer layer. Along with a layer of blubber on the inside of their skins, this fur helps keep them warm in the freezing water they like to fish and play in. Sadly, this has also made them the target of much violence, as seal fur coats were a sought-after fashion item not too many decades ago. Fortunately, fur has become a huge taboo in the fashion industry and seal-hunting is now illegal in most countries.
