This is a group of ungulates with an even number of hooves, and at present has developed the most diversity among large mammals that live on land. Also, most large livestock animals today were created from this group.
Wild boars are omnivorous, but animals in the same group such as cows, giraffes, deer, camels and hippopotamuses only eat plants, and in order to properly digest their food, they regurgitate food for re-chewing.
