Giant Moray Eel, Gymnothorax javanicus (Bleeker)
The largest of the moray eels, growing up to 3 m. Quite common and always interesting to observe. Feeds primarily on fish, occasionally on crustaceans and octopus. Morays live in holes and generally hunt by night. You may see them rhythmically opening and closing their mouths. They do this to maintain a respiratory current past the gills. Morays undergo a sex change during growth, changing from male to female.
