Considered the biggest fish in the world, a large pod of Whale Sharks  (scientific name: Rhincodon typus), locally known as Butanding, converge  annually just at the mouth of the long and winding Donsol  River in the Municipality of Donsol.  This phenomenon occurs starting October of each year, and peaks during the  months of February, March, April and May. It is believed that these Whale  Sharks, about 30 to 40 of them at any one time, converge off the Donsol waters  to feed on plankton, krill and juvenile fish, which are the only food of these  giant fishes. In spite of their awesome size, the Whale Sharks are gentle and  harmless and allow humans to swim or interact with them. This phenomenon, found  only in the waters off Sorsogon, particularly Donsol, has attracted hundreds of  tourists around the world eager to interact with these gentle giants of the  sea.
