The large mammal group typically includes horned animals, antlered animals, bears, and large members of the wild cat or wild dog families.

Horned or antlered animals have these key characteristics.

• Horns are hollow and are not shed. Wild sheep and goats have horns.
• Antlers are solid bone and are shed annually. Members of the deer family have antlers and rub their antlers on trees.
• Horned and antlered animals are cloven-hoofed (their hooves have two parts).
• Horned and antlered animals are ruminants (they chew cud). A ruminant digests its food in two steps. First they eat food and regurgitate it (cud), and then they eat it a second time. They have a hard upper pad that they use to mash their food.
