The Mediterranean moray, or Muraena helena, is one of the most intriguing and iconic predators inhabiting Malta’s rich underwater landscapes. Sleek, secretive, and equipped with a formidable set of sharp, backward-pointing teeth, this eel-like hunter is a master of stealth across the reefs of Malta, Gozo, and Comino.

Its distinctive appearance; muscular, finless, and covered in thick, scaleless skin patterned with mottled yellows and browns makes it instantly recognisable to divers who are lucky enough to glimpse one.

Reaching lengths of up to 1.5 metres, though more commonly between 60 cm and 1 metre, the Mediterranean moray’s body is perfectly adapted for navigating the complex architecture of rocky reefs. Cylindrical toward the head and laterally compressed near the tail, the moray can effortlessly slide into tight crevices, caves, and wreck openings. These shadowy spaces are its preferred daytime hideouts, where it waits patiently for nightfall.

The moray is a nocturnal ambush predator, emerging under darkness to hunt fish, crustaceans, and cephalopods. Its jaw structure is especially effective - once prey enters its mouth, escape is nearly impossible. Despite this fierce reputation, the Mediterranean moray is naturally shy and avoids human contact. The rhythmic opening and closing of its mouth, often mistaken for aggression, is simply its way of breathing, pumping water across its gills.

However, like any wild animal, a moray may defend itself if cornered, so divers should observe respectfully from a distance. Admiring the moray as it peers from its rocky shelter offers a thrilling glimpse into the hidden world of Malta’s marine predators.

Spotting a Mediterranean moray is always a memorable moment – have you ever since one?
