The Australian sea lion is a marine mammal native to the southern coast of Australia. They are known for their distinctive, robust bodies and large, expressive eyes. Adult males can weigh up to 300 kilograms, while females are smaller, averaging around 50 kilograms. These sea lions have a thick layer of blubber that helps them stay warm in cooler waters. Australian sea lions primarily feed on fish, squid, and crustaceans. They are social animals, often found in groups on sandy beaches or rocky shores. Their population is currently classified as vulnerable due to habitat loss and human activities, making conservation efforts essential for their survival.
