How old does a Australian sea lion get? (age expectancy)

What is the maximal age a Australian sea lion reaches?

An adult Australian sea lion (Neophoca cinerea) usually gets as old as 16 years.

Australian sea lions are around 266 days in the womb of their mother. When born, they weight 7.14 kg (15.75 lbs) and measure 3 cm (0′ 2″). As a member of the Otariidae family (genus: Neophoca), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 1.8 meter (5′ 11″).

As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.

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.
