Have you ever had a bad neighbor? The kind that blasts heavy metal at 3AM, “exercises” their dog on your lawn, and is just an all-around jerk? Well, bad as they were, chances are that you didn’t have to worry about them eating you. Our ancient, 375 million year old cousin Tiktaalik wasn’t as lucky.
Many species, including crows, chimps, and capuchin monkeys, are known to use tools, but a new paper in Coral Reefs by A. M. Brown et al. (paper free at link and highlighted in Science NOW) reports what may be the first documented case of a tool-using fish.
This blackspot tuskfish, found in Australia's Great Barrier Reef, held a clam in its mouth and smashed it against a rock to reach the food inside. This photo is the first incontrovertible proof that fish are capable of tool use.
