Southeast Atlantic: South Africa. Indo-Pacific: South Africa to Red Sea and (Ref. 3257), eastward to the Tuamoto and Austral islands, north to the Ryukyu and Hawaiian islands, south to New Caledonia. Eastern Pacific: Costa Rica, Panama and the Galapagos (Ref. 9324).
Lunghezza alla prima maturità / Dimensione / Peso / Età
Maturità: Lm ?, range 65 - ? cm
Max length : 240 cm TL maschio/sesso non determinato; (Ref. 48635)
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 0; Spine anali: 0; Raggi anali molli: 0; Vertebre: 132 - 140. Reddish eyes (Ref. 1602). Color yellowish, densely mottled with dark brown; front of head purplish grey; posterior margins of fins yellow-green; gill opening in a black blotch. Juveniles sometimes bright yellow with brown blotches (Ref. 48635).
Body shape (shape guide): eel-like; Cross section: compressed.
Along drop-offs (Ref. 48635). Benthic (Ref. 58302). Occurs in coral or rocky areas of reef flats and protected shorelines to seaward reefs. Feeds on cephalopods (Ref. 30573), fishes, and crustaceans (Ref. 89972). Most often appears on the reef after a fish has been speared during daylight. The regularity and promptness of such appearances make it clear that G. flavimarginatus is especially sensitive to stimuli emanating from an injured or stressed fish (Ref. 13550). Eaten in some parts of the Indo-Pacific (Ref. 12484). Minimum depth reported taken from Ref. 128797. Solitary and curious, usually seen with head protruding (Ref 90102).
