The Shark Whale:

The mating of a Shark and a Whale produce what is known as a 'Shark Whale'. Nobody has ever witnessed this act as there are only a few of these creatures known to exist. The bulk of the whale and the ferocity of the shark combine to produce an effective creature that although isnt as fast as a shark, is much more powerful.

The Shark Whale lives much longer than the normal shark, while shorter than the whale, but due to complications , no Shark Whale can reproduce, giving it a very lonely existence. Because of this , the Shark Whale is not actually considered a species and is not considered en-dangered. Several hunters spend years searching for Shark Whales, to display them as trophies on their death ridden walls.
