The scorpionfish are Perciforms with a squat and spiny body, covered with rough scales. The head is cuirassed with plates and bony ridges and armed with strong horns. The dorsal is unique, it has an elongated spiny part and a smaller soft part; the anal is provided with 3 spines. The caudal in is rounded at Scorpaena scrofa. They are coastal or deep benthic fish. Widely distributed in all the world’s seas, they are particularly diversified in the Indo-Pacific. They are confined preferably on the rocky bottom to which they integrate thanks to their mimicry. Thus hidden, they hunt on the lookout for small fish and crustaceans passing within their reach. The spines of the scorpionfish have, at their base, a venom gland making their bites dangerous but not fatal, at least among the Atlantic species. Their flesh is edible and very popular for the preparation of fish soups. Scorpaena scrofa is a fish that can each 40 cm long. His body is stocky; his massive head is covered with many rags of skin. His eyes are surmounted by a short tentacle and his mouth is very wide. Its dorsal fin is indented, going from head to tail. The anterior part of this fin has hard spiny rays containing a virulent venom that can inflict extremely painful stings.
