Mediterranean Moray
Muraena helena
The Mediterranean moray is a large, nocturnal eel of rocky reefs and cave systems in the eastern Atlantic and Mediterranean. It hides in crevices by day and hunts fish and crustaceans at night; it is not a common angling target.

Identification points
- Long, muscular eel body with no pelvic fins and a continuous dorsal-fin fringe
- Dark brown to mottled pattern with pale spots or speckling on the head and body
- Broad head with thick jaws and a mouth often agape, showing large teeth
Habitat
Rocky reefs, ledges, caves, and rubble-bottom habitats, usually from shallow water to deeper sublittoral reefs; commonly shelters with only the head exposed.
Bait notes
Best taken incidentally on cut fish, squid strips, or oily baits fished close to reef structure. Large natural baits work better than lures; it is rarely targeted on artificials.
Behavior
Nocturnal ambush predator that relies on scent and sudden strikes; spends daylight hidden in holes and becomes more active at dusk and night, often with a strong territorial response when hooked.
Caution
Very sharp teeth and a powerful bite; handle only with long tools or gloves. Seafood safety can be an issue in some areas because morays may accumulate ciguatera-related toxins, so local consumption advisories matter.
Fishing notes
If targeting or avoiding, work near rocks and caves with heavy abrasion-resistant tackle and short leaders. Use a steady bait soak rather than fast retrieves; beware of snagging and toothy bites when unhooking.
