Fish have a protective outer covering known as scales, which are made of a hard substance called enamel or bone. These scales help reduce friction as the fish swims and provide protection against parasites and injuries. Additionally, some fish have a slimy mucus layer over their scales that further aids in protection and streamlining. In certain species, the outer covering can also serve as a form of camouflage or display for communication.
