The Public Library of Science (PLoS) has released a fascinating article that details a new discovery: Groupers and Moray Eels coordinating to hunt for food in the Red Sea. Groupers can hunt quickly over a reef, but if prey goes into a crevice, it can’t be reached. Enter Madame Moray, who quickly dives in and continues pursuit. Groupers and Morays have been seen hunting, swimming side by side, looking like two friends out for a stroll. Apparently the grouper solicits the moray with a special nod of the head at the entrance to the moray’s hole. Fascinating! We so underestimate animals. You can read the entire article here.
