The horn shark is a small shark with a blunt head and two tall fins, each with a large spine at the front. It lives along the western coast of North America, from California to the Gulf of California. It spends its days hidden in caves and crevices and hunts at night.1

Adults live in shallower water, usually 2 to 11 m deep, on rocky reefs and in algae beds. Juveniles prefer sandy flats in deeper water, 40 to 150 m deep. In winter, adults move to water deeper than 30 m.1

Adults eat mostly hard-shelled molluscs, sea urchins and crustaceans, which they crush with their flat back teeth. They suck prey out of the sand and rocks, and can lever loose prey free with their body.1

Horn sharks are harmless unless they are harassed. They are not targeted by commercial or recreational fisheries, though small numbers are caught by accident.1

During the day they stay still in hiding places, but they swim away quickly if disturbed.1

1

For its size, the horn shark has the strongest bite of any shark that has been measured.1

2

To pull prey loose, the shark pushes its head up with a downward stroke of its tail. No other shark has been seen doing this.1

3

Large horn sharks that eat many sea urchins can have purple-stained teeth and fin spines.1

4

A Pacific angelshark was filmed trying to swallow a juvenile horn shark, but spat it out because of the spines.1

5

Horn sharks have only 148 electroreceptors (ampullae of Lorenzini), far fewer than most sharks, which may have over 2,000. They rely mainly on smell to find food.1

6

A dropped tooth takes about 4 weeks to be replaced.1
