Many mammals live in wildlife in various forests, some of them live in aquatic environments such as whales, and some of them live in trees.
These species spent about a million years in evolution until they came out to us in this current form, and they are one of the most prominent types of vertebrates, which bear other characteristics that distinguish them from the rest of the species, most notably the large size of the head and hair that covers the body in many of their types.
Mammals are divided into three main types: placental mammals, cystic mammals, and primary mammals. We review each type separately as follows:
placental mammals
