Description

The viper moray is a large moray (Muraenidae) from the Indo-Pacific. The species grows to about 2.5 metres and has an elongate, snake-shaped, dark-brown, scaleless body with a strongly curved jaw full of long, needle-sharp, non-closing teeth that give it a viper-like look. As a nocturnal reef predator it hides by day in crevices and seizes fish and octopus at night. It bites very fiercely when disturbed; handle with care.
