A recent video shot by Cody Peterson off the coast of Destin, Florida, using an arial drone, shows hundreds of 5-7 foot long black-tip sharks just loitering around.
So, what exactly are these sharks doing, loitering around in such large numbers? Well, no one really knows.
"Why they do this at times isn't well understood but it probably involves feeding and migration. Autumn is coming and water temperatures are coming down, and that may cue the sharks to prepare for moving south for winter," said Robert Hueter of the Mote Marine Laboratory to AL.com
