Editing Incisor (section)

===Other animals===
Among other animals, the number varies from species to species. [[Opossum]]s have 18, whereas [[armadillo]]s have none. Cats, dogs, foxes, pigs, and horses have twelve. [[Rodent]]s have four. Rabbits and hares ([[lagomorph]]s) were once considered rodents, but are distinguished by having six—one small pair, called "peg teeth", is located directly behind the most anterior pair. Incisors are used to bite off tough foods, such as red meat.

[[Cattle]] (cows, bulls, etc.) have none on top but a total of six on the bottom.
