Brown Fur Seal

Fascinating facts about the Brown Fur Seal

• Male African fur seals tower at an average 2.3 m (7.5 ft) and weigh between 200 kg and 300 kg, making them the largest and most robust fur seals. Females are smaller at about 1.8 m (5.9 ft) and 120 kg. This size gap fuels fierce male competition for territories during the October breeding rush, where dominant bulls guard harems of up to 50 females.
• Since May 2024, 39 rabies cases were confirmed in Western Cape seals and 16 in the Northern Cape, with a further 1 case in the Eastern Cape in June 2025. Genetic sequencing links the virus to a canid strain from black-backed jackals, suggesting jackal bites introduced the disease to pups on Namibia's coast. In densely packed colonies, constant biting spreads the virus rapidly, making rabies the first known endemic marine-mammal outbreak worldwide.
• African fur seals can plunge to 204 m (669 ft) and stay underwater for up to 7.5 minutes, far deeper than their Australian cousins who average 120 m (394 ft) dives. which make up 70 % of their diet.
• Brown fur seal pups are born weighing 4.5-7 kg and measuring 60-70 cm, with a black, curly coat that molts to olive-gray after 4-5 weeks. By seven months they can swim for two to three days straight.
