NATIONAL GEOGRAPHIC– A blackspot tuskfish off Australia has its mouth full as it
carries a cockle to a nearby rock, against which the fish was seen repeatedly bashing the
shellfish to get at the fleshy bits inside.
A recent study in the journal Coral Reefs says the picture—snapped at a depth of nearly 60 feet (18 meters) in Australia’s Great Barrier Reef in 2006—is the first ever taken of a tool-using fish in the wild.
Professional diver Scott Gardner was just about out of air and swimming back to the surface when he heard an odd cracking sound nearby. Swimming over to investigate, he spotted the foot-long (30-centimeter-long) fish at work.
“When Scott showed me his photos, I said ‘Wow, this is quite amazing,'” said study co-author Alison Jones, a coral ecologist at Central Queensland University in Rockhampton, Australia.

That’s not just logic. That’s ralely sensible.
