Distinguishing features
This is one of the larger moray species, growing to at least a metre. Colour pattern is distinctive: head is yellow/greenish, body and fins have large, close-set dark brown blotches that tend to form irregular vertical bars, and there are small dark spots in the much paler spaces between the blotches. There is no dark spot on the gill opening as in the Giant Moray, Gymnothorax javanicus.
