Scuba diver swims among one of the world's most bizarre fish

This scuba diver cannot contain his joy when he finds himself among some of the world's most elusive and unusual fish. These are ocean sunfish, commonly called Mola Mola. They resemble giant heads with fins and no tails and they are extremely clumsy looking animals. They drift slowly on the current, although they can actually swim at slow speeds to move throughout the day. They are also capable of impressive speeds for very short distances to avoid predators.
Small Mola Mola are often prey to a variety of sharks, tuna, sea lions, and many types of large fish, but once they reach full size, their thinck skin makes them difficult to eat.
