Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino associati a barriera corallina; distribuzione batimetrica 2 - 55 m (Ref. 30874). Tropical; 22°C - 28°C; 43°N - 40°S, 95°E - 130°W (Ref. 55292)
Pacific Ocean: Cocos-Keeling Islands and Western Australia (Ref. 27362) in the eastern Indian Ocean to the Marquesas and Oeno (Pitcairn group), north to southern Japan and southern Korea, south to Lord Howe Island, northern New Zealand, and the Austral Islands. Replaced by the very similar Pterois miles from the Red Sea to Sumatra.
Lunghezza alla prima maturità / Dimensione / Peso / Età
Maturità: Lm ?, range 16 - ? cm
Max length : 45.7 cm TL maschio/sesso non determinato; (Ref. 118189); peso massimo pubblicato: 1.4 kg (Ref. 118189); Età massima riportata: 10 anni (Ref. 72479)
Spine dorsali (totale) : 13; Raggi dorsali molli (totale) : 9 - 12; Spine anali: 3; Raggi anali molli: 6 - 8. Scales cycloid (Ref. 37816). Variable in color, usually in relation to habitat. Coastal species generally darker, sometimes almost black in estuaries. Often with large tentacles above eyes (Ref. 48635).
Body shape (shape guide): fusiform / normal.
Inhabit lagoon and seaward reefs from turbid inshore areas to depths of 50 m. Often solitary, they hide in unexposed places at daytime often with head down and practically immobile. Pelagic juveniles expatriate over great distances and the reason for their broad geographical range (Ref. 48635). Hunt small fishes, shrimps, and crabs at night, using its widespread pectorals trapping prey into a corner, stunning it and then swallowing it in one sweep. Dorsal spines are venomous; the sting can be treated by heating the afflicted part and application of corticoids (Ref. 5503). A popular table fish.
