Graham's Swallowtail, Odontanthias grahami, from off northern New South Wales - freshly dead holotype, AMS I.32142-010, 9.3 cm SL. Source: John E. Randall / FishBase. License: CC by Attribution-NonCommercial


A rare pale pink and yellow deepwater anthiid with a broad blackish-yellow submaginal band on soft portion of the dorsal fin, and the caudal fin with a yellow base and bright pink lobes and outer margins. Graham's Swallowtail, known from very few specimens, may be a junior synonym of Odontanthias xanthomaculatus which was described from New Caledonia (Gill & Russell 2019).
