Rhincodon typus
The whale shark is the largest known fish. It reaches 15 m in length, and may reach 18 m or more. Its weight can exceed 10 tons. This creature ranges all tropical waters, and infrequently strays into temperate ones. It is mainly solitary in nature, and, despite its impressive appearance, it is harmless to humans. Scuba divers and underwater swimmers have clambered unmolested over its body. The whale shark feeds chiefly on plankton, but also consumes sardines and anchovies.
