Fish

Fish are the oldest vertebrates, with about 32,100 named species distributed in various waters on Earth, of which China has about 2,500 species, most of which live in seawater, with more than 1,500 marine fish and about 800 freshwater fish. In the past, fish were usually divided into two categories, cartilaginous fish and bony fish, based on the similarities and differences in the properties of their bones.
