Animal Weight

How much does a Australian sea lion weight?

It is hard to guess what a Australian sea lion weights. But we have the answer:

An adult Australian sea lion (Neophoca cinerea) on average weights 189.14 kg (416.98 lbs).

The Australian sea lion is from the family Otariidae (genus: Neophoca). It is usually born with about 7.14 kg (15.75 lbs). They can live for up to 16 years. When reaching adult age, they grow up to 1.8 meter (5′ 11″). Usually, Australian sea lions have 1 babies per litter.

As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.

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 currently monotypic in the genus Neophoca, with the extinct Pleistocene New Zealand sea lion Neophoca palatina the only known congener. 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 a 5-month breeding cycle and a 17-18 month aseasonal breeding cycle, compared to other pinnipeds which fit into a 12-month reproductive cycle. Females are either silver or fawn with a cream underbelly and males are dark chocolate brown with a yellow mane and are bigger than the females.
