Deer are hoofed ruminant ungulates of the family Cervidae.
Cervidae is divided into subfamilies Cervinae and Capreolinae. Male Deer of almost all species, as well as female reindeer, grow and shed new antlers each year. Chevrotains, or Mouse-Deer, are small, even-toed ungulates that make up the family Tragulidae, and are the only living members of the infraorder Tragulina. Mouse‑Deer are tiny, secretive ungulates native to the tropical forests of Southeast Asia, they live in the dense understory of lowland forest. Despite its name, it is neither a Mouse nor a true Deer, but the smallest hoofed mammal in the world. With a reddish‑brown coat and delicate white throat markings, it blends easily into dappled forest light.
