Diver Snaps First Photo of Fish Using Tools

sciencehabit writes with this excerpt from Science: "While exploring Australia's Great Barrier Reef, professional diver Scott Gardner heard an odd cracking sound and swam over to investigate. What he found was a footlong blackspot tuskfish holding a clam in its mouth and whacking it against a rock. Soon the shell gave way, and the fish gobbled up the bivalve, spat out the shell fragments, and swam off. Fortunately, Gardner had a camera handy and snapped what seem to be the first photographs of a wild fish using a tool." (Not everyone agrees that this constitutes tool use, says the article, in part because the "tool" isn't something that the fish can actually manipulate.)

A fish beat the crap out of a clam by hitting it against a rock? I'm not quite sure this qualifies as "tool" use. Now, grabbing the rock, and beating clam with it, or using it to pry open the clam... that would sound more "tool-like."
