Quick Summary

The Australian sea lion (Neophoca cinerea) is a species of eared seal found along the southern coast of Australia. Adult males typically measure 2.0–2.5 meters in length and weigh up to 300 kg, while females are smaller, reaching about 1.5 meters and weighing less than 100 kg. Sea lions, like the Australian sea lion, belong to the family Otariidae and are characterized by short, coarse hair and the ability to rotate their hind flippers forward, allowing them to move more effectively on land compared to true seals. They primarily feed on fish, crustaceans, and cephalopods. Breeding occurs in herds, with males defending harems of females, and pups are born after a 12-month gestation period.12
