The small prey are engulfed in the mouth and then filtered near the surface of the shark's gills as water passes out through the large gill slits. The Basking Shark filters 350,000 gallons of water an hour, and its stomach can contain up to half a ton of plankton at one time. The basking shark can be found traveling in schools of up to 100 individuals in temperate waters of the Atlantic and Pacific Oceans.
