Looking at a diagram, I realize that the foot in Tridacna is not so exposed. Tridacna are anatomically cockles that are mostly missing the front end. The foot and byssus are, in life position, on the underside. A loose Tridacna, turned on its side, would have a vulnerable foot, but probably that's not what was seen in the aquarium.
