How many baby Australian sea lions are in a litter?

A Australian sea lion (Neophoca cinerea) usually gives birth to around 1 babies.

Each of those little ones spend around 266 days as a fetus before they are released into the wild. Upon birth, they weight 7.14 kg (15.75 lbs) and measure 3 cm (0′ 2″). They are a member of the Otariidae family (genus: Neophoca). An adult Australian sea lion grows up to a size of 1.8 meter (5′ 11″).

They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.

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.
