The California horn shark is a bottom-dwelling fish that grows to be about 3 to 4 feet (0.9 to 1.2 m) long. It has rounded fins, a blunt snout, ridges over the eyes, a dorsal fin spine, and is light brown with dark brown spots. It lives in kelp beds far offshore California, USA, spending a lot of time resting on the bottom. This slow-moving shark is harmless to people, but its spines do sting when they are touched. It hunts at night and eats sea urchins, crabs, worms, anemones, and other bottom-dwelling invertebrates. It has small, pointy teeth in the front of its mouth, and flat teeth in the back (these are good for grinding hard-shelled prey).
