The Australian Sea Lion is a marine mammal native to the southern and southwestern coasts of Australia. They are characterized by their robust bodies, external ear flaps, and long front flippers. Adult males can weigh up to 300 kilograms, while females are smaller, averaging around 50 kilograms. These sea lions are known for their playful behavior and social structures, often forming large colonies on beaches and rocky shores. Australian Sea Lions primarily feed on fish, squid, and crustaceans, using their keen eyesight to hunt underwater. They are unique among pinnipeds as they breed on a two-year cycle, with pups born on sandy beaches. Conservation efforts are in place to protect their habitats and address threats such as fishing nets and habitat degradation.
