Brown Moray

Overview

The Brown Moray (Gymnothorax unicolor) is a relatively rare, benthic species of moray eel found throughout the Mediterranean Sea and parts of the eastern Atlantic Ocean. Like other members of the Muraenidae family, it is a secretive, serpentiform fish that typically resides in rocky crevices and shadowed areas.

Distribution & habitat

This species is primarily distributed across the Mediterranean and the adjacent eastern Atlantic, including the Azores, Madeira, the Canary Islands, and Cape Verde. It is a bottom-dwelling fish that prefers rocky coasts, cliffs, and areas with gravel or sand, typically occupying depths between 10 and 80 meters.

Appearance

The Brown Moray has an elongated, scale-less body that is uniform in color, ranging from brown to reddish-brown. It features a massive, high head with a darker facial area that can resemble a mask. Its dorsal, caudal, and anal fins are merged into a single continuous cutaneous crest, which is edged with a thin, light-colored border. The species lacks pectoral and ventral fins and possesses two small, forward-pointing tubular nostrils on its snout.

Biology & behavior

This eel is a nocturnal hunter that relies on a highly developed sense of smell to locate prey. It is generally solitary and territorial, often remaining hidden within holes or crevices during the day. While it is considered harmless, it is a predator that should not be disturbed.

Feeding

The Brown Moray is a carnivore that feeds primarily on small crabs, gastropods, and cephalopods. It uses its powerful jaws and specialized teeth to capture and consume its prey.
