The whitetips are hunting....anything. Pack hunting by the whitetip reef sharks is a sight to behold. They remind one of a pack of wild dogs, except without the social structure. This is purely opportunistic and its every shark for himself! The pics aren't great, because the sharks kick up a bunch of sand when they hunt. Oh, they didn't let us night dive the site where this happens for the first half of the trip because this also happens to be the dive site where the tigers had taken up residence and the divemasters didn't want us in the water at night with the tigers.
