Short description Morfologia | Morfometria

Spine dorsali (totale): 0; Spine anali 0; Vertebre: 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.

Biologia     Glossario (es. epibenthic)

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).

Observations on prespawning behavior include a pair entwined around one another lying on the bottom of the reef area (Ref. 93344).
