Yes, although dolphins are similar to fish in shape and live in water, they are not fish, but a mammal. As an aquatic mammal, dolphins have some of the same characteristics as terrestrial mammals. One of the most important characteristics is their breeding method. Dolphins reproduce in viviparous way, and there will be lactation after production. Moreover, their breathing pattern is the same as that of other mammals. They breathe with their lungs. 1、 What animals are dolphins? Dolphins are whales. Most of them are small toothed whales. Dolphins also have many species, and their distribution areas are different. Generally speaking, they are widely distributed in salt and fresh water such as oceans, inland seas and rivers all over the world. Dolphins are also a very ancient mammal. They have existed for more than 20 million years. Through the changes of environment, the body structure of dolphins has also undergone great changes.
Dolphins are also very fast mammals. They are even faster than sharks. They are one of the fastest creatures in the water. Their hearing is also very good, whether they are in the water, or when they stay in the air or on land. 2、 Is dolphin a mammal? As already introduced above, dolphin is a mammal. Although they live in the same environment as most fish, they can not be mistaken for fish. As an aquatic mammal, dolphins have some characteristics consistent with terrestrial mammals.
One of the most important characteristics is their breeding method. Dolphins reproduce in viviparous way. Moreover, the pregnancy period of dolphins is relatively long, about 11 months; After birth, dolphins have lactation, which is similar to humans and other mammals. In addition to the breeding mode, another important feature is their breathing mode. They breathe with their lungs, which is also consistent with other mammals. Therefore, dolphins cannot be considered as fish. （HaiTunShiShenMeDongWu，ShiBuRuDongWuMa）
