fishes

Fishes are aquatic animals characterized by gills for breathing, fins for movement, and a backbone, making them vertebrates. They live in a wide range of water environments, from freshwater rivers to oceans. Fishes vary greatly in size, shape, and behavior, from tiny seahorses to large sharks. They reproduce mainly by laying eggs, and their bodies are often covered with scales that provide protection. Fishes play a vital role in aquatic ecosystems by maintaining balance, serving as food for other animals, and supporting fishing industries. They are an essential and diverse group of vertebrates adapted to life underwater.
