Question

Why do some species of fish have scales?

Answer 1

Fish scales serve several important purposes for the fish. They provide protection from predators, parasites, and injuries. They also help reduce friction when swimming, allowing fish to move more efficiently through water. Additionally, scales can help regulate the fish's body temperature and maintain buoyancy.

Fish scales serve as a protective layer on their skin, helping to reduce water resistance, improve their swimming abilities, provide defense against predators, regulate body temperature, and maintain buoyancy. Scales also play a role in camouflage and can help fish blend in with their environment.
