Does bony fish have a body covering?

Bony fish, also known as teleosts, possess various types of body coverings. The most common covering is made up of scales. These scales are composed of several layers of collagen fibers and are covered in a layer of skin. The scales of bony fish can be of various shapes and sizes and can be either smooth or spiny.

In addition to scales, some bony fish species may also have other types of body coverings such as bony plates, called scutes, or even skin that is covered in small dermal denticles, which are small, tooth-like structures.

Overall, the body covering of bony fish serves several functions, including protection from predators and the environment, streamlining for efficient swimming, and providing support and flexibility.
