The undulated moray has a distinctive pattern of light undulating lines and speckles on a dark green background, with a snout that is often yellow. It is a common species on reef flats among rocks, rubble, or debris and it also occurs in lagoons and seaward reefs, commonly inhabiting caves. It is a nocturnal species that feeds on fishes, octopuses, and probably crustaceans.

It is reported to be an aggressive species and prone to bite. It is used in Chinese medicine.
