About
Overview
The Mediterranean moray is a distinctive, eel-like marine predator found throughout the Mediterranean Sea and the eastern Atlantic Ocean. Known for its territorial nature, this species is frequently observed resting in rocky crevices or coral holes with its head exposed, often keeping its mouth slightly open to reveal sharp teeth.
Distribution & habitat
This species inhabits subtropical marine environments, ranging from the British Isles down to Senegal, including the entire Mediterranean basin. It is typically found in reef-associated areas, favoring rocky seabeds, crevices, and caves where it can find shelter.
Appearance
The Mediterranean moray possesses an elongated, serpentine body that is vertically compressed and lacks scales. Its skin is smooth and typically displays a mottled pattern of yellow and brown. A continuous, undulating fin crest runs along its back, around the tail, and along the underside of its body.
Biology & behavior
Primarily nocturnal, this moray is a solitary and territorial animal that maintains high site fidelity. While it has a reputation for being aggressive due to its threatening appearance, it is generally non-confrontational and typically only attacks if provoked. It is a long-lived species, with some individuals reaching up to 38 years of age.
Feeding
As a predator, it hunts mainly at night, feeding on a diet that includes fish, crabs, squid, and octopuses. It relies on an excellent sense of smell to locate its prey within the rocky terrain it inhabits.
