Whale is the name of cetaceans in marine mammals, which can be divided into toothed whales and baleen whales. Among cetaceans, the dolphin family is included. Whales live in the ocean. Whales have a very thick layer of fat under their skin, that is, whale oil, which can keep whales warm and store energy for emergencies.
Because there are many special structures in the whale, it can hold its breath for a long time and slow down its heartbeat, so when it sinks to the bottom of the sea, it will take a long time to surface again. In addition to the structure of storing oxygen, when a certain part of the body needs a lot of blood supply, the body will have a special centralized supply function.
Whales are viviparous mammals, not fish. It takes a year for calves to grow up on breast milk. Fish are oviparous vertebrates. Parent fish generally have no habit of taking care of small fish.
Whale's "fins" actually evolved from limbs. Fish is not. Whales breathe with their lungs; Fish breathe through gills. Whales are warm-blooded animals; Fish are warm-blooded animals. You can't tell a whale from a fish by whether it has scales or not. Because many fish have no scales.
