Moray eel
Nomes alternativos: Muraenidae
Moray eel is a marine species but they can also be found in brackish or fresh water. They have a serpentine body flatted at the sides and usually they come in a variety of colors, some of them can even have the ability of changing their color for camouflage.
An interesting fact about Moray eels is the cooperative hunting. Because Moray eels are good hunters, roving coral groupers recruit giant morays in order to join them in a hunt.
As the grouper hunts in open waters and the moray eel looks for the prey in cracks and crevices they make a wonderful and efficient team together.
