What is a "tusk"?

A tusk is a long, pointed, and often curved tooth that protrudes from the mouth of certain animals, most notably elephants, walruses, and narwhals. These elongated teeth are typically made of ivory, a dense and durable material. Tusks serve various purposes depending on the species. They can be used for defense, digging, gathering food, or as a display of dominance during mating rituals. The size and shape of tusks can vary greatly between species and even individuals, with some reaching impressive lengths. Tusks are iconic features of these animals and hold cultural and historical significance.
