Fish are aquatic vertebrate animals that constitute a diverse and numerous group. They are characterized by having elongated bodies covered in scales, gills for breathing underwater, and fins that allow them to move and swim.
Their adaptation to the aquatic environment provides them with abilities such as the capacity to swim rapidly, capture prey, and defend against predators.
Fish are found in a wide variety of aquatic habitats, from oceans to rivers and lakes.
In addition to their ecological importance, fish are valued for their use in commercial and sport fishing, and also as pets in aquariums.
