Description

The Starry moray is a moray (Muraenidae) from the Indo-Pacific. The species grows to about 180 cm and has a robust, snake-shaped, scaleless body. The dark body is scattered with white star-spots and the mouth cavity is bright yellow; the skin mucus is toxic, so do not eat. As a secretive reef predator it hides in crevices of coral and rocky reefs by day and seizes fish, crustaceans and squid at night. It bites fiercely when disturbed; handle with care.
