Photo of Fish Using a Rock to Open a Clam
Tool use, once thought to be the distinctive hallmark of human intelligence, has been identified in a wide variety of animals in recent decades…
There have also been a handful of reports of fish cracking open hard-shelled prey, such as bivalves and sea urchins, by banging them on rocks or coral, but there’s no photo or video evidence to back it up, according to Culum Brown, a behavioral ecologist at Macquarie University in Sydney, Australia, and a co-author of the present paper, to be published in a forthcoming issue of Coral Reefs.
The more we learn about animals the more tool use we find. It is continually interesting to see the wide variety of behavior documented.
