Photo-monitoring Whale Sharks: Largest Fish In The Sea Appear To Thrive Under Regulated Ecotourism

http://www.sciencedaily.com/releases/2007/12/071226003604.htm --- ScienceDaily (Dec. 28, 2007) — Up to 20 meters long and weighing as much as 20 tons, its enormous size gives the whale shark (Rhincodon typus) its name. Known as the 'gentle giant' for its non-predatory behavior, this fish, with its broad, flattened head and minute teeth, eats tiny zooplankton, sieving them through a fine mesh of gill-rakers. Listed as a rare species, relatively little is known about whale sharks, which live in tropical and warm seas, including the western Atlantic and southern Pacific.
