A fish is an animal that lives in water and breathes with gills, using fins to swim. Catfish fits this description because it spends its life in rivers and lakes and has gills and fins to move and breathe underwater. Eagles are birds with feathers and wings, not aquatic animals. Frogs are amphibians; they live both in water and on land and have moist skin, not scaled bodies with gills like fish. Turtles are reptiles with shells and scaly skin, also not fish. So catfish is the fish.
