The whale shark is the largest fish on the planet. It reaches a length of 18 meters and weighs more than 20 tons.
The whale shark differs from other sharks in its enormous size, spotted pattern, and peaceful plankton diet. It is important for the ocean as a water filter and part of the marine food web.
