Groupers Use Gestures to Recruit Morays For Hunting Team-Ups

Groupers Use Gestures to Recruit Morays For Hunting Team-Ups.

Groupers use gestures to get morays eel to help them hunt. The groupers are good at catching prey in the open water, whereas the moray eels are good at flushing the prey out of crevices. Apparently the sea trout do this with octopus!
