Ahh I have only seen 4-5 sharks at one time - but two were about 9' Sipadan. But have never seen the feeding frenzy. Maybe some day. It looks so cool.
It is awesome, Onespeed can vouch for that, Though I must say, I didn't know what to think as when the boat pulls up the Sharks come running like a dinner bell went off, and that seems to me that they associate Humans with food, knowing they are going to get fed.
