In many omnivorous mammals, such as a gorilla, they are adapted for shearing sharply. In cats, the incisors are small; biting off meat is done with the canines and the carnivals. In elephants, the upper incisors are modified into curved tusks (unlike with Narwhals, where it is a canine that develops into a straight and twisted tusk).[1] The incisors of rodents grow throughout life and are worn by gnawing.
