Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 36.0 cm TL mâle / non sexé; (Ref. 9710); common length : 30.0 cm SL mâle / non sexé; (Ref. 37816)
Épines dorsales (Total) : 12; Rayons mous dorsaux (Total) : 9; Épines anales: 3; Rayons mous anaux: 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).
