Green moray eels are the largest moray species in the Caribbean, reaching nearly 2.5 metres, and the groove sections at Radar Reef provide the shelter and hunting territory they require. Their uniformly green colouration — actually yellow skin beneath a blue-green mucus — and the constant pumping motion of their jaw as they ventilate their gills makes them formidable in appearance but generally placid toward divers. They are important nocturnal predators of octopus and fish, often hunting cooperatively with goatfish or groupers in a mutualistic foraging relationship.
