Biggest Fish

The world's biggest fish is the rare plankton-feeding whale shark (Rhincodon typus), which is found in the warmer parts of the Atlantic, Pacific, and Indian Oceans. The largest specimen on record, captured in 1949, was 41 ft. 6 in. long, measured 23 ft. around the thickest part of the body, and weighed an estimated 14.8-20.7 tons.
