Description

The Slenderjaw moray is a moray (Muraenidae) from the eastern Pacific, off Central and South America. The species grows to about 91 cm and has a robust, snake-shaped, scaleless body with conspicuously curved jaws that do not fully close, leaving the long, glass-sharp fangs exposed. The body is plain brown. As a secretive reef predator it hides in crevices by day and seizes fish and squid at night. It bites fiercely and the sharp teeth inflict deep wounds; handle with care.
