Sharks are scary. We definitely overreact (for example: trying to kill them all), but there’s no denying that a large, toothy creature that has evolved into a nearly perfect hunting machine is a little unnerving. But how about those goliath groupers? Who’d a thunk that a grouper, the sea-cow of the fish world, would lay such a serious smack down on a four-foot black tip? Granted, it is a bit of an opportunistic move, but still. It’s a grouper eating a shark.
