What kind of fish do sea fish have? What are the common sea fish

There are many kinds of sea fish, such as shark, COD, salmon, salmon, eel, bass, grouper, pomfret and so on. These fish live in the ocean, but the water area is also different. The fish living on the water surface can't swim too deep, and the fish adapting to the deep sea can't reach the upper layer of the water body. In addition, some fish have migratory characteristics and will swim to fresh water to lay eggs in the breeding season. 1、 Sharks are the most dangerous sea fish. This kind of fish has a large body shape and fast swimming speed. Its bones are cartilage. Although it will calcify, it has no real bone tissue. Its exoskeleton is underdeveloped and its teeth are diverse. Because of its many kinds, its body shape is also inconsistent, some large and some small. 2、 Hairtail hairtail is also a kind of fish. Its character is fierce, its body is silver gray, but its tail is black, and its length is generally about 1 meter. It is distributed in the Western Pacific and Indian Ocean, and it is also one of the main seafood in China. Its swimming ability is relatively poor. It will float on the surface of the sea during the day and fall to the bottom of the sea at night. 3、 Grouper grouper is a warm water large and medium-sized fish, which is widely distributed in tropical and subtropical waters. It has many species and generally inhabits near coral reefs. As solitary fish, it will swim in groups only during breeding period. This fish also has the ability to change sex. It first matures into a female and becomes a male after one year of reproduction. 4、 Salmon, also known as salmon, is a cold water anadromous migratory fish, mainly distributed in the back of the Pacific Ocean and the Arctic Ocean. This kind of fish is about 60 cm long and will migrate during the breeding period. After entering the freshwater basin, they will stop feeding and die after spawning. （HaiYuDouYouShenMeYu，ChangJianDeHaiYuYouNaXie）
