Tamaño / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 300 cm TL macho / no sexado; (Ref. 9710); peso máximo publicado: 30.0 kg (Ref. 30404)
Espinas dorsales (total) : 0; Espinas anales: 0; Vértebra: 137 - 143. Juveniles are tan with numerous large black spots. Adults have black specks that grade into leopard-like spots behind the head and a black area surrounding the gill opening.
Found in lagoon and seaward reefs. Commonly seen species along deep drop-offs and slopes in Indonesian waters (Ref. 48635). Benthic (Ref. 58302). Juveniles more secretive and occur on intertidal reef flats (Ref. 37816). It feeds primarily on fishes and occasionally on crustaceans. This is the largest Indo-Pacific moray eel (Ref. 30404), perhaps reaching 3 m in length. Because of its position at the top of the reef's food chain it is often ciguatoxic. Attacks humans when provoked (Ref. 3132). Minimum depth reported taken from Ref. 10713. Solitary in reef holes (Ref 90102).
