Behaviors

Cape fur seals are permanent (non-migratory) residents in their territories, but spend most of their time out at sea. They prefer rocky offshore islands to the mainland, which are visited through generations as pupping (birthing) areas.

Social and Reproduction

Highly gregarious, with some colonies numbering over 3000.

Mating System Polygamy (Polgyny)
Breeding interval Mating will occur usually about 6 days after a female has given birth.
Breeding season Mid October, with breeding occurring in November/December.
Gestation 368 days
Number of offspring Single calves are born, weighing between 4.5-7kg.

Habitat and Food

Habitat

Cape fur seals spend most of their year offshore at sea; mostly on islands and parts of the mainland coast in Namibia to Port Elizabeth.

Food

Fish make up 70% of the South African Fur Seals diet, with squid making 20% and crustaceans, cephalopods and sometimes even birds making up the rest.

Predators

Sharks, killer whales, jackals and brown hyenas (predating on coastal colonies), pollution, and humans.

Conservation Challenges

Pollution and prosecution by fishing vessels for ‘net raiding’ indiscriminately kills or injures thousands of cape fur seals annually.
