Man is the top of the food chain, but that’s only because of our brains. One giant Goliath Grouper reminded one fisherman that they are still not to be messed with. After catching a fish with a spear-gun, a huge Goliath Grouper pounced on the diver’s fish and ran off with it. The diver ended up being dragged around for a bit until the spear finally broke.
