How big does a Australian sea lion get? Here is an overview over the average adult age:
A grown Australian sea lion (Neophoca cinerea) reaches an average size of 1.8 meter (5′ 11″).
When born, they have an average size of 0 cm (0′ 0″). During their lifetime of about 16 years, they grow from 7.14 kg (15.75 lbs) to 189.14 kg (416.98 lbs). A Australian sea lion has 1 babies at once. The Australian sea lion (genus: Neophoca) is a member of the family Otariidae.
As a reference: Humans reach an average body size of 1.65m (5′ 5″) while carrying 62 kg (137 lbs). A human woman is pregnant for 280 days (40 weeks) and on average become 75 years old.
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.
