The sea lion is a charismatic Marine mammal, loved by people for its agile movements and intelligent performance. They belong to the seal family and are closely related to seals, walruses and other animals. Sea lions are usually large and have streamlined bodies that are suitable for swimming in the water. Their forelimbs evolved into flippelike structures that allowed them to be flexible in water, while their hind limbs were used for walking on land.

Sea lions have complex social behaviors and usually live in groups. During the breeding season, male sea lions occupy territories, attract females, and engage in intense competition. This competition is not only a contest of strength, but also a contest of voice. Males use low growls to demonstrate their strength, intimidate other competitors and attract females. During the rearing period, mother sea lions take good care of their young, teaching them how to hunt and survive.

The sea lion's diet is dominated by fish, squid and other Marine life. They have excellent swimming abilities, able to hold their breath underwater for up to 20 minutes while diving 200 meters deep to hunt. Sea lions are very flexible in their hunting methods, often using a cooperative group to catch, showing great intelligence and strategy.

In recent years, with the increase in human activities, sea lions' habitat has been threatened, especially by overfishing and imbalances in the food chain caused by Marine pollution, which pose a threat to their survival. In order to protect this species, many areas have begun to implement conservation measures, including limiting fishing and creating Marine protected areas.

In addition to being found in nature, sea lions are often used for educational and recreational activities. In aquariums and Marine parks, trained sea lions display various acrobatics, attracting a large number of visitors.
