1. The blue whale is the largest animal in the world known to mankind. Its whole body is blue-gray. The largest blue whale ever caught was in 1904, near the Falkland Islands in the Atlantic Ocean. This blue whale is 33.5 meters long and weighs 195 tons, which is equivalent to the weight of 35 elephants.

2. The sperm whale has a heavy head and a light tail, like a huge tadpole. Its head takes up one-third of its body, and it looks like a big box. Its favorite food is the deep-sea king squid.

3. Sea lions roar like a lion, and some species have a mane on their neck, which looks quite like a lion, hence their name. Its four legs are like fins and are very suitable for swimming in the water. The sea lion's hind legs can bend forward, allowing it to walk flexibly on land and squat on the ground like a dog. Although sea lions sometimes land on land, the ocean is their real home. Only in the sea can they catch food and avoid enemies. Therefore, they spend most of the year cruising at sea in search of food.

4. Sea snakes are venomous snakes that live in seawater throughout their lives. Sea snakes have upward-facing nostrils with valves that can open and close. After inhaling air, they can close their nostrils and dive underwater for up to 10 minutes. They live in coastal waters, especially in brackish water estuaries, and feed on fish. Except for a few sea snakes that lay eggs, the rest all give birth to young and are ovoviviparous. ?

5. Turtle is the general term for marine turtles. There are 5 species of marine turtles living in my country's oceans (there are only 7 species in the world), mainly distributed in the Xisha Islands and the port of Huidong County, Guangdong Province, followed by the coastal areas on the outskirts of Sanya and Lingshui County, Hainan Province. Five species of sea turtles have been recorded in the China Sea: leatherback turtles, sea turtles, loggerhead turtles, hawksbill turtles and olive ridley turtles, all of which are nationally protected animals.
