Found in temperate waters around the globe, particularly along continental shelves, this species is a bottom-dwelling predator that feeds primarily on small fish and invertebrates. The Spiky Dogfish Shark is recognised for its ability to thrive in colder waters and is often found at depths ranging from shallow coastal areas to deep ocean floors.
