A series of shots including the one above are thought to be the first photographic evidence from the wild of a fish using a tool. It shows a blasckspot tuskfish about to smash a cockle against a rock to expose its flesh for eating. Scott Gardner took the photos back in 2006 at a depth of 60 feet in Australia's Great Barrier Reef. Scienctists have just now published their study on the images and related data, titled 'Tool use in the tuskfish Choerodon schoenleinii?.' 'Carry-out Cockles'
