Diver Snaps First Photo of Fish Using Tools 118

Posted by timothy from the wake-me-when-they-enter-asynchronous-trade dept.
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.)

        It makes a difference. If we accept that acting against the natural environment qualifies as tool-use, then walking is an example of tool use, since you're using the ground in order to propel yourself. If your definition of tool use is that broad, you end up with all kinds of absurdities.
