Poisson au corps de couleur jaune d'or et parfois blanc nacré au niveau du ventre ou dans certains cas jusqu'au dos. Des petites taches blanc bleuté plus ou moins vives sont présentes sur les joues et sous l'oeil. La nageoire dorsale épineuse se termine souvent en voilure translucide, de même pour les nageoires anale et caudale. Plus rarement, le dessus de la dorsale peut être teinté de bleu. Le juvénile est blanc nacré avec les rayons des nageoires jaunes. De nuit la livrée nocturne présente quatre grosses rayures marrons ainsi que deux gros points blancs sur le ventre. Taille maximum : 13.0 cm TL. Profondeur : 3 - 45 m, généralement: 12 - 45 m.
Etymologie
Amblyglyphidodon : du Grec, amblys ou amblus = émoussé, usé (en parlant d'une lame) + du Grec, glyphis = tailler, sculpter + du Grec, odous = dent.
aureus : du Latin, aurum = or (métal), doré (couleur).

Description
Dorsal spines (total): 13; Dorsal soft rays (total): 12-16; Anal spines: 2; Anal soft rays: 14-15; Pectoral rays: 16-18; Lateral-line scales: 16-17; Gill rakers: 25-29; Body depth: 1.5-1.7 in SL. Dorsal profile from snout to dorsal fin origin steep, slightly curved. Interorbital space slightly larger than eye diameter. Mouth small oblique, terminally located; maxillary reaching below anterior margin of pupil. Ventral margin of lacrimal smoothly concave. Lacrimal and infraorbital with two to five scales. Predorsal scales reaching beyond nostril. Dorsal spines gradually increasing in length posteriorly; last dorsal spine longest, subequal to or slightly less than 2nd anal spine length. Length of 1st anal spine subequal to eye diameter. Soft dorsal and anal fins produced into a point. Caudal fin forked, with the lobes pointed. Pelvic fin long; 1st ray produced into a filament, reaching to base of anterior anal rays. Max length: 13.0 cm TL. Depth range: 3 - 45 m, usually: 12 - 45 m.
Color
Body golden yellow, with blue spots on scales of head and body.
Etymology
Amblyglyphidodon: from Greek, amblys or amblus = dull (blade: not sharp), blunt, obtuse + from Greek, glyphis = carved + from Greek, odous = teeth.
aureus: from Latin, aurum = gold, golden.

Biology
Adults occur in steep outer reef, occasionally in deep lagoons and along channel walls, usually in current prone habitats and where there are abundant gorgonian and long sea-whip corals on which they lay and guard eggs. Juveniles in small groups often found among large sea fans or black corals. Feed on zooplankton. Oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Eggs laid usually on gorgonian dead branches. Males guard and aerate the eggs.
Similar species
Amblyglyphidodon flavopurpureus (Allen, Erdmann & Drew, 2012) - Reported from Cenderawasih Bay, West Papua, Indonesia. Depth range: 10-30 m on steep slopes, often around sea fans or black coral. It was initially thought to be a colour variant of Amblyglyphidodon aureus, but has beenshown genetically to be distinct.
