Most of them are first-order aquatic animals that have not lived out of water during the evolution of the species, but there are also second-order aquatic organisms such as whales and aquatic insects that have been transformed from terrestrial animals, some of which do not rely on dissolved oxygen in water for respiration. According to the habitat, it can be divided into two types: marine animals and freshwater animals. In vertebrates, the osmotic pressure of body fluids is generally between that of seawater and freshwater, so there is a reverse situation between marine and freshwater animals in terms of the osmotic regulation mechanism of body fluids.
The most common aquatic animals are fish (fish), in addition to coelenterates such as sea anemones, jellyfish, and polyps; molluscs such as squid, octopus; crustaceans, such as shrimp, crabs; Other animals such as dolphins (mammals), turtles (reptiles), and other creatures.
