Groupers and coral trout perform a pointing signal to
indicate the location of hidden prey
Fish have the ability to communicate with each other while
hunting their prey in ways that were previously known only for humans, great
apes, and ravens, according to new research.
A study led by Alexander Vail, a Gates Cambridge Scholar at
the University of Cambridge's Department of Zoology, found that groupers and
coral trout perform a pointing signal to indicate the location of hidden prey
to cooperative hunting partners including moray eels, octopuses and Napoleon
wrasses.
