Bottom line is you don't have to worry about them. Jump in and enjoy. Swim towards one and watch it slowly swim away from you. I have seen a video of a goliath grouper grabbing a guys arm. But I sure don't think people are afraid of grouper. It is all psychological. I am sure there is an instance of a barracuda that mistook something shiny on a diver and went for it. It is not a reason to fear them at all. Enjoy them. Don't let them ruin a trip or a swim/snorkel. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Wink.gif" alt="" />
