Drawing of a goat skull showing arrangement of teeth.
Goats have no incisors in their upper jaw; instead they use the incisors at the front of the bottom jaw to chomp up against a bony pad at the front of the upper jaw. They have no canine teeth and have numerous premolars and molars at the back of the jaw for chewing and granding their plant food.
