Here's a great scuba diving video showing off the enormous number of hammerhead sharks off Cocos Island, Costa Rica in Central America. There's over 5 minutes of schooling hammerheads, as well as straight on shots, side views and more. The hammerhead shark is my personal favourite, so it's a thrill just to watch these animals glide underwater.
