South American Fur Seal

The South American fur seal (Arctocephalus australis) breeds on the coasts of Peru, Chile, the Falkland Islands, Argentina, Uruguay and Brazil. South American fur seals are of least concern on the IUCN Red List. The total population is around 300,000-450,000. Populations are affected by hunting and environmental stressors.Arctocephalus australis have a dark grey or brown fur coat and are sexually dimorphic. Males compete for territory and females to mate with, forming a dominance hierarchy. Breeding season is from October to December, whereas multiple pups are bred each season. South American fur seals are nocturnal, carnivorous hunters that primarily eat demersal and pelagic fish. They are social and often hunt in groups. Communication within the species occurs through a variety of vocalizations, such as guttural threats, barks, whimpers, or submissive calls from the males and growls or high-pitched wails to gather pups from females. Four subspecies may be recognized: A. a. australis (Falkland Island fur seal), A. a. gracilis (South American fur seal), A. a. forsteri (New Zealand fur seal), and an unnamed species (Peruvian Fur Seal).
