The animals possess teeth, which are suited to the consumption of a specific diet. The herbivores, carnivores, and omnivores may have some overlap in the shape and size of the teeth, however, observing all the teeth in the jaw can give a clear idea of the kinds of food each animal depends on.
An animal can be determined just by looking at the placement of the teeth and looking at the skull. All the animals possess teeth, which are amended to consuming specific kinds of food. For example, herbivores are plant eaters, thus, they exhibit flat and strong molars, which are formed for grinding leaves, and having small or no canine teeth.
Carnivores are the meat eaters, thus, they exhibit defined canine teeth for tearing of meat, in combination with a restricted number of molars. Omnivores, as they consume both plants and meat, exhibits a combination of both molars for grinding and sharp anterior teeth.
