How would you describe a tail?

A tail is an elongated appendage that extends from the rear of an animal's body, often used for balance, communication, or locomotion. It can vary widely in shape, size, and function across different species, from the fluffy tails of cats to the long, slender tails of fish. In some cases, tails serve as a means of expressing emotions or signaling to others within the same species. Overall, a tail plays a significant role in an animal's interaction with its environment.
