The sharks live on all the oceans .There are more than 300 different kinds.Most are hunter they hunt the animals with their teeth.

Great with sharks like to surprise their prey below  and kill it with only one bite , to save energy.They sometimes attack swimmers but scientist believe .They do this by mistake,thinking that humans are other sea animals.

Sharks like dolphin and whales sometimes swim hear the surfaces of the sea with their dorsal (back) fins sticking out of the water.Dorsal fins of different animals look different ,as you ca see below.

Most sharks have at least three rows of teeth .As they lost the ones in front, teeth from the rows behind move forward to replace  them
