A Correct answer
Explanation

Dogfish are small sharks, which belong to the class Pisces (fish). More specifically, they are cartilaginous fish (Chondrichthyes). They are not mammals (which have hair and mammary glands), reptiles (which have scales and lay eggs on land), or amphibians (which typically have metamorphic life cycles). As fish, they have gills, fins, and live entirely in water.
