Bayanai

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
