The first time I saw this was on the Winch Hole. A graysby came to a stop on a pile of rubble, and a goldentail came out from its lair. At first they just sort of looked at each other, then came cheek to cheek, touched, and took off together.\u003c\/p\u003e\u003cp\u003eI have seen it a couple of other times with a green moray and black grouper.\u003c\/p\u003e\u003cp\u003eThis behavior has not been greatly documented according to the research I did this week. I could only find a few scientific references based on cooperation and communication between different fish species.\u003c\/p\u003e\u003cp\u003eOther cooperative hunting behaviors among single species are well documented - from dolphins to chimpanzees - but inter-species communication coupled with cooperative behavior studies among fish are rare.\u003c\/p\u003e\u003cp\u003eThere are many relationships of joint foraging, such as wrasses hanging out with trunkfish. These involve a nuclear species (the main dude) and a follower (the one cleaning up the scraps).\u003c\/p\u003e\u003cp\u003eWhat differentiates the grouper\/eel behavior is the grouper seeks the eel and communicates its intention to hunt with a specific signal.\u003c\/p\u003e\u003cp\u003eThe one study all the other scientists referenced was done in the Red Sea. Google “Plos Biology grouper eel” and the paper should pop right up for you. It’s called “Interspecific Communicative and Coordinated Hunting between Groupers and Giant Moray Eels in the Red Sea”, with principal investigator Redouan Bshary.\"\u003c\/p\u003e","brand":"Tim Grollimund","offers":[{"title":"Default Title","offer_id":47103565103344,"sku":"2940154403143","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940154403143_p0.jpg?v=1764066586","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940154403143","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
