Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range ? - 400 m (Ref. 100719). Tropical; 30°N - 36°S, 24°E - 171°E
Indo-West Pacific: Red Sea and Sodwana Bay, South Africa (Ref. 4313) to the Mariana Islands (Ref. 9710), north to Taiwan; Palau and Guam in Micronesia; probably more widespread.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 36.0 cm TL male/unsexed; (Ref. 9710); common length : 30.0 cm SL male/unsexed; (Ref. 37816)
soft rays: 5. Highly variable in color. Adults 'bearded' with numerous tassels. Juveniles slender with tall dorsal fin (Ref. 48635). Third dorsal spine longest (2.05-2.5) in head; occipital pit absent or very shallow; snout very long (2.7-3.0 in head length); space between opercular spines naked; first dorsal spine short (1.85-2.5) in length of second spine; supraocular and postocular spines broadly joined in adults (only tip of supraocular spine showing) and flaring outward to form a shelf over posterior half of eye (Ref 42181).
Inhabits clear-water outer reef slopes and channels from depths of 1 to at least 35 m, in areas with mixed rock and coral substrates. Venomous spines. Solitary on coral and rocky bottoms (Ref 90102).
