Artiodactyls and artiodactyls differ in how to identify.

Artiodactyls are most common on earth. They are subdivided into ruminants (cows, rams, deer) and non-ruminants (hippos, wild boars). Equid-hoofed animals are not so numerous (horses, zebras, tapirs, rhinos). 1. The structure of the hoof. In artiodactyls, the division of the hoof into two parts is clearly visible. These are two developed fingers. In artiodactyls, only one middle finger is developed. It looks like one whole hoof. 2. Ruminant artiodactyls have a multichamber stomach. Artiodactyls are single-chambered. 3. Most ruminants have horns.
