Gymnothorax castaneus Panamic green moray, Morena verde Most morays are not aggressive toward humans, but it is unwise for divers to thrust their arms blindly into crevices and holes.
Morays are capable of inflicting painful wounds, sometimes causing serious permanent injuries.
The moray's body is compressed, very elongated, and muscular. The large mouth has caniniform fanglike teeth. The posterior nostrils lack tubes, and the snout is usually sharply pointed. Moray eels lack pectoral fins, but the dorsal and anal fin are well developed, though largely hidden by tissue. The moray's range extends from the Gulf of California to Malpelo island in Colombia.
