Environment: milieu / climate zone / depth range / distribution range
Écologie
marin récifal; profondeur 5 - 350 m (Ref. 86942). Tropical
Indo-Pacific: Red Sea, Indonesia, Fiji, Samoa, and Tonga. Recently recorded from Reunion (Ref. 53568).
Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 45.0 cm TL mâle / non sexé; (Ref. 48636)
Épines dorsales (Total) : 4; Rayons mous dorsaux (Total) : 12 - 13; Épines anales: 13. Recognized by the black first dorsal fin (Ref. 48636). Body with distinctive black spots. Respiratory valve inside lower jaw with a thread-like brownish appendage and several long filaments around is base. Upper edge of opercle ascending backward. Posterior nostril a slit-like pore or with a very low tubular valve. First dorsal fin with V spines (last one rudimentary). Only 1 basipterygial process. No cirrus on eye (Ref 42788).
Inhabits reef flats and coastal bottoms (Ref. 9710) but is rarely seen because it lies buried in sand or mud most of the time, with only the eyes showing. When buried, the cirri on the edge of the mouth serve to keep out the sand during respiration. The oral lure is used to attract the prey within striking range of the mouth. The shoulder has a venomous cleithral spine; wounds can be serious.
