All hoofed animals belong to the family of ungulates, widely divided into two sub-categories. These are the even-toed ungulates – animals that place most of their body weight on two of their toes on each limb – and the odd-toed ungulates – fauna that relies on three of their toes concerning their body weight.
Interestingly, cetaceans, like whales and dolphins, are also classified under the same family, even though they do not have hooves. This is because they have evolved from the same ancestors.
Most hoofed animals are herbivorous, though some, like pigs and boars, are omnivorous. They also tend to be ruminating animals, possessing gut bacteria that help break down the complex substances in plants for easy consumption.
