I've heard stories of giant clams being so large they could swallow a diver.....but I never realized how dangerous they could be, until today. I was working on one of our restoration projects at Anantara, next to a giant clam. I didn't realize my depth gauge was not secured....until it was "swallowed" by the clam. I waited about 15 minutes for it to open back up, to no avail. My air supply was low, so I had to ditch my gear and swim to the surface. Fortunately, my buddy was able to free my gear 30 minutes later.
