Environment: milieu / climate zone / profondeur / distribution range
Écologie
marin récifal; profondeur 1 - 50 m (Ref. 58047), usually 5 - 30 m (Ref. 26938). Tropical; 42°N - 30°S, 99°W - 13°W (Ref. 55256)
Western Atlantic: New Jersey (USA), Bermuda, and northern Gulf of Mexico to Brazil. Recorded once from Nova Scotia, Canada. Eastern Atlantic and eastern Pacific (Ref. 26340).
Taille / Poids / Âge
Maturité: Lm ? range ? - ? cm
Max length : 250 cm TL mâle / non sexé; (Ref. 7251); common length : 150 cm TL mâle / non sexé; (Ref. 5217); poids max. publié: 29.0 kg (Ref. 9710)
Very large brown moray, uniformly dark green to brown (Ref. 26938).
Body shape (shape guide): eel-like.
A benthic and solitary species (Ref. 26340) occurring along rocky shorelines, reefs, and mangroves (Ref. 3255).Usually found shallower than 30 m (Ref. 26938). Due to its large size and aggressiveness, the bites of this moray are particularly dangerous (Ref. 3255). Feeds mainly at night on fish and crustaceans (Ref. 42064). Marketed fresh and salted (Ref. 3255). Large individuals are ciguatoxic (Ref. 3255).
