A collar is a distinct band, ring, or marking encircling the neck or throat region. It can vary in appearance, ranging from a broad and prominent band of fur, feathers, or skin to a more subtle or fine line. The collar may have a different color, texture, or pattern compared to the rest of the body, creating a visual contrast. Some animals, such as certain bird species or mammals, possess collars that are particularly prominent, serving as an important feature for identification and distinguishing individuals. The collar can play a role in communication, display, or camouflage, depending on the species.

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.
