Fish Uses Tool to Get Food

Turns out fish may be a little smarter than initially thought. At least, that's the way it seems after an orange-dotted tuskfish was recorded using a tool to get food.



In the video, which was shot by Giacomo Bernardi, a professor of ecology and evolutionary biology at the University of California, Santa Cruz, the fish is seen digging for a clam shell in shallow water off the coast of Palau. Once it finds the shell, it swims to a rock, throws the claim shell against it, retrieves it, and tries to crush it again several times, using the rock as an anvil.

"What the movie shows is very interesting," Bernardi said in a press release. "The animal excavates sand to get the shell out, then swims for a long time to find an appropriate area where it can crack the shell. It requires a lot of forward thinking, because there are a number of steps involved. For a fish, it's a pretty big deal."

According to Jennifer Viegas at Discovery News, this isn't the first instance of fish using tools to be caught on camera. A blackspot tuckfish was photographed earlier this year using the same trick to retrieve food
