Clever Trout Match Chimpanzees in a Cognitive Challenge | Science | WIRED

As demonstrated in a series of experiments published today in Current Biology, coral trout not only solicit the help of moray eels when they hunt, but also pick their hunting partners wisely. They know when they need help, and quickly learn which eels best provide it. It’s a seemingly simple yet surprisingly sophisticated cognitive trick.

“Prior to our study, chimpanzees an humans were the only species known to possess both of these abilities,” said zoologist Alex Vail of England’s University of Cambridge. “I think the evidence is mounting that fish have more going on in their heads in terms of cognition than they have been given credit for.”
