The adults do not have a false eyespot or ocellus on their dorsal fin. The juveniles have a bar towards the tail and an ocellus on the dorsal fin, these fade and eventually disappear as the fish matures. The dorsal fin contains 9-10 spines and 29-33 soft rays while the anal fin has 3 spines and 21-22 soft rays. This species attains a maximum total length of 18 centimetres (7.1 in).
Chelmon marginalis is endemic to Australia where it is found from the Houtman Abrolhos in Western Australia around the coasts of northern Australia to the northern Great Barrier Reef and the reefs in the Coral Sea off Queensland.
Chelmon marginalis is found largely on coastal coral and rocky reefs, it can be found on the outer reef slopes, drop off and around islands close to the shore as well. It is a carnivorous species which preys on benthic invertebrates such as crabs, shrimps and polychaetes. This is normally a solitary species which forms pairs to breed, breeding is oviparous.
