Cetacea is a traditional taxon under the phylum Mammalia, including about 90 species of fish-like, naked-skinned aquatic mammals and their early extinct relatives, collectively referred to as cetaceans or cetaceans. Traditionally, the big ones are called whales and the small ones are called dolphins. Most of them live in shallow water, and a few species live in fresh water. The whale's body structure and living habits are obviously different from those of any mammal, so it has been listed as an order for a long time. Its ancestors and evolutionary history were once controversial, but with the continuous progress of related research, it has been completely confirmed that cetaceans evolved from terrestrial cloven-hoofed animals after entering the water 50 million years ago. DNA sequencing shows that cetaceans and hippos are sister groups, and their branches and ruminants are sister groups. In order to prevent cloven-hoofed animals from becoming a joint group (that is, lacking some evolutionary branches), whales are classified as cloven-hoofed animals in the current classification and downgraded to Cetacea.
