The Whale Shark is the largest fish in the ocean. It is considered as the most friendly of sharks and is harmless to humans. Whale Sharks feed on Plankton and small fish and can be easily seen feeding on the surface of the water. The Whale Shark is a slow mover, swimming at approximately 5km/h at top speed. Due to them being slow movers and surface feeders they are extremely easy to catch and are unfortunately still actively fished in the waters off Taiwan. Whale Sharks are fished for their liver oil for waterproofing and their Fins and meat for food as a delicacy.

Whale Sharks have been held successfully in an aquarium in Japan but special conditions and Dietary needs fortunately make it very difficult for most aquariums to house these sharks.
