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

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

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

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

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

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