The Australian sea lion (''Neophoca cinerea'') also known as the Australian sea-lion or Australian sealion, is a species of sea lion that is the only endemic pinniped in Australia.〔 It is monotypic in the genus ''Neophoca''. These Sea-lions are sparsely distributed through Houtman Arbrolhos Islands (28°S., 114°E.) in Western Australia and The Pages Islands (35°46’S., 138°18’E) in Southern Australia. With a population estimated at around 14,730 animals, the Wildlife Conservation Act of Western Australia (1950) has listed them as “in need of special protection”. Their Conservation status is listed as endangered. These pinnipeds are specifically known for their abnormal breeding cycles, which are varied between 5 months breeding cycle and a 17-18 month aseasonal breeding cycle, compared to other pinnipeds which fit into a 12 month reproductive cycle. ==Phylogeny== The Australian sea lion is a pinniped, most closely related to other species of sea lions and fur seals in the family Otariidae. Australian sea lions and fur sea lions make up the Otariide family, which are eared seals. These mammals use their flippers to propel themselves in water and can walk on land with their flippers. Australian sea lions share distinct features with other sea lions. These include short fur, short flippers and a bulky body.
