Description
Max length: 240 cm TL (male/unsexed).

Color: Highly variable; generally brown to blackish, densely mottled with light brown to whitish spots. Coloration sometimes consisting of very small indistinct dark brown spots which may fuse to form larger irregular patches. Median fins narrowly edged with white posteriorly; corner of mouth often dark; gill opening always in a dark brown or black blotch.

Head 8.0-9.2, depth of body 14.8-17.5, both in total length. Tail equal to or about ½ length of head longer than head and trunk. Head 2.9-3.4 in trunk. Eye diameter 8.3-10.4 in head, 1.4-1.7 in snout and 1.1-1.4 in interorbital space. Anterior nostrils tubular, on each side of tip of snout, posterior nostrils above anterior edge of eye, with slightly raised rims. Cleft of mouth 2.2-2.5 in head. Teeth in single series in jaws, those near the symphysis longer than others; maxillary with an inner row of 2-3 teeth; premaxillary with a median series of 2-3 fang-like teeth; vomer with 2 irregular series of small teeth. Dorsal fin origin nearer to gill opening than to corner of mouth.

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 Gymnothorax flavimarginatus is especially sensitive to stimuli emanating from an injured or stressed fish.
Feeds on fishes and crustaceans.
