I spend a lot of time in the Indian ocean and when I hunt I do fairly long aspettos around 2-3minutes. Very often during this period of stillness on the bottom reef sharks swim in very close to me they come right at me until I turn and make eye contact with them and often jerk in surprise. My concern is what happens when I don't see them coming and they are on top of me-are they going to take a probing bite or bump me or what. I know they aren't that aggressive but I know I'm a foreign object lying still on the bottom that they must be curious about. anyone have similar experiences, tips? thanks
