Etymology: Aulacocephalus: Greek, aulos = flute + Greek, kephales = head (Ref. 45335). More on author: Bleeker.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 20 - 350 m (Ref. 58488), usually - m (Ref. ). Tropical; 0°C - ; 20°N - 36°S

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 40.0 cm TL male/unsexed; (Ref. 9710)
Inhabits caves and crevices in rocky reefs (Ref. 9710). Skin contains grammistin which imparts a bitter taste. The amount of toxin produced increases when the fish is frightened (Ref. 4326). Minimum depth reported taken from Ref. 09710.
