The world's oceans are home to many different species and plants, from tiny organisms like plankton to the world's largest animal, the blue whale. Deep down in the seas' depth, you will even find some monstrous-looking creatures that seem to have come straight out of a fairy tale. Did you know, for example, that male anglerfish feed on the female's blood? And is it true that the giant clam can trap a diver's leg? Or have you ever heard of fish that hitch a ride on sharks?
