Probably the Einstein of Whale SharksConservation International has posted a great video on its Youtube channel. It shows a beautiful whale shark sucking on a fishing net and eating the small fish that spill out.
In Indonesia's Cendrawasih Bay, whale sharks often congregate around bagan (lift net) fishing platforms to eat the small silverside baitfish that the fishers are targeting. Sometimes the sharks swim right into the nets and become entangled. They have also learned how to "suck" the fish out of holes in the nets.
The whale shark is currently categorized as a vulnerable species on the IUCN Red List. They can be found in all tropical and warm-temperate seas.
