Fish Integument

Fish integument refers to the outer covering of a fish, primarily composed of skin and scales. This layer acts as a protective barrier against injuries, infections, and environmental hazards. It also helps regulate the fish’s body fluids and supports sensory functions through specialized cells. The scales, embedded in the skin, vary in type and structure depending on the species, offering additional protection and sometimes aiding in movement. Overall, the integument is essential for a fish’s survival, helping it stay healthy and adapt to its aquatic environment.
