Fish are aquatic vertebrates with gills, fins, and streamlined bodies adapted for swimming. They come in diverse species, inhabiting freshwater and saltwater environments worldwide.
Fish exhibit remarkable adaptations, such as scales for protection, lateral lines for sensing movement, and swim bladders for buoyancy control.
They play essential ecological roles as both predators and prey, contributing to aquatic food chains. Fish are also a significant food source for humans, with various species consumed for their nutritional value.
