: 6 - 8. Scales cycloid (Ref.

). 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
).
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.
