The greyface moray eel, also called the freckled moray, slender moray, or white-eyed moray,[1] Gymnothorax thyrsoideus, is a species of marine fish in the family Muraenidae.
Description
The Greyface moray is a medium-sized fish that is most commonly observed at lengths of around 40 cm, reaching a maximum length of 66 cm.[2][3] Its body is serpentine in shape, is speckled with small dark spots and has a predominantly beige color that can vary in strength between different eels . The head is grey with distinctive white eyes. Here is a video of the eel in its natural habitat.
Distribution and habitat
The greyface moray is widespread throughout the Indo-Pacific area from India and the Maldives to Polynesia and from south Japan to Australia and New Caledonia.[4]
This moray likes shallow and somewhat turbid waters from lagoons, protected reefs and areas rich in debris like wrecks around 35 meters deep.[5]
Biology
The greyface moray is a carnivore of benthic fish. During the day, it sits in a shelter, often with other morays. When night arrives it leaves its lair and actively hunts prey, consisting of small fish and crustaceans.
