The walrus is a relatively large animal that lives in the ocean. If we classify walruses by category, then walruses belong to Mammalia, Walrus Family, so they are mammals. Many people think that walruses are not mammals because they live in water and their living environment is different from that of terrestrial animals, which is actually a wrong view. Walrus is a very typical mammal that lives in the water, and some of its very important characteristics are the same as those of terrestrial mammals.
One of the most important characteristics of walruses is their reproductive mode. Like other mammals, walruses reproduce viviparously. Moreover, the walrus's lactation period is relatively long, sometimes close to 2 years, during which time the female walrus will accompany the young walrus until the end of lactation. Then there is the way of breathing, walrus breathing with lungs is also in line with the characteristics of mammals. In addition, walrus is also a warm-blooded animal, while mammals are typical warm-blooded animals. Walrus thick skin has a thermal effect, so that even if they live in high latitudes, they can maintain a constant temperature.
As mentioned above, the walrus lives in the ocean and is a marine mammal. They need to live in the water most of the time. Specifically, walruses mainly live in higher latitudes in the northern hemisphere. Especially in the waters near the Arctic region, the number of walruses is relatively large. They are mainly distributed in the Arctic Ocean, in addition to the northern Pacific Ocean and the Atlantic Ocean at higher latitudes. Up to about 40 degrees north latitude, there may be walrus distribution, but there is basically no walrus further south.
