Dimensione / Peso / Età
Maturità: Lm ?  range ? - ? cm
Max length : 140 cm TL maschio/sesso non determinato; (Ref. 30573)
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 0; Spine anali: 0; Raggi anali molli: 0; Vertebre: 128 - 135. Greyish and speckled with irregular, dark markings (Ref. 3257). Young yellowish with hollow-centered spots which becomes less conspicuous with age (Ref. 3257). Lacks the molariform teeth as well as the depressible vomerine fangs present in most Gymnothorax and have two rows of vomerine teeth (Ref. 37816).
Body shape (shape guide): eel-like.
Adults inhabit reef flats and rocky intertidal shorelines. Feed on small fishes and crustaceans, sometimes leaving the water in pursuit of prey (Ref. 9710, 48635). Benthic (Ref. 58302). Simultaneous hermaphroditism is confirmed for this species (Ref. 103751). Caught with various nets (Ref. 30573). Solitary (Ref 90102). Minimum depth reported taken from Ref. 86942.
