The devil fish (Choridactylinae) are a subfamily of the stone fish (Synanceiidae). They live in the Red Sea , in the tropical Indian Ocean and in the western Pacific on sandy and scree bottoms to depths of 90 meters. Often they bury themselves up to their raised eyes on bones. If they change their location, they move very slowly so as not to be recognized by predators. They feed carnivor of crustaceans , fish and cephalopods .

features

Devil fish are twelve to 29 centimeters long and are more gracefully built and usually smaller than the actual stonefish of the subfamily Synanceiinae . Your body is covered with frayed growths. The poisonous rays of the dorsal fin are higher than that of the actual stone fish. The soft rays of the fins are divided. The freestanding lower rays of the ventral fins are used to move slowly across the sea floor. In dangerous situations, the caudal fin and the pectoral fins are spread and the inside of the pectoral fins, which are marked with striking warning colors, are shown.

Fin formula : dorsal XII – XVIII / 5–10, anal II / 8–13, ventral I / 5
