Tail
Tail
Tail (/teɪl/), from the Old English tægel, is a flexible extension of the torso, found on many animals, including humans in a vestigial form known as the coccyx.
Anatomy
In animals, the tail is an important part of their body as it aids in balance, locomotion, and in some species, defense and communication. It is made up of multiple vertebrae, muscles, and in some cases, bones. In humans, the tail is represented by the coccyx or tailbone, a small, vestigial structure at the base of the spine.
Functions
The functions of the tail vary greatly depending on the species. In some animals, like cats and kangaroos, it is used for balance. In others, like peacocks and birds, it is used for display and communication. Some animals, like scorpions and stingrays, use their tails for defense.
