good material thanks http://thisav.fun/ thisavcom The study was conceived by Robert Hueter, a marine biologist at Mote Marine Laboratory in Sarasota, Fla. Hueter swims with sharks, and has done so for 40 years, but he has a special fondness for whale sharks. "This is the largest fish as far as we know that's ever existed â there's nothing bigger in the fossil record," he explains. "But it's a very unusual kind of shark in that it's not a top predator; it feeds on plankton."
