The teeth are all pointed and conical and there are 4 to 6 canines in front of each jaw. The first two spines of the dorsal are very short, the third, fourth and fifth are long and slender, at least in the young; in the elderly, these thorns become dull, but there is a strong hump on the forehead, hence the name of Gibbosus. The body is pinkish, more or less reddish, without stain at the base of the last rays of the soft ridge, or very much reduced; on the other hand, there is a dark spot at the origin of the lateral line and the caudal fin is bordered by a fine black border. It is a coastal species of sandymuddy or gravelly bottom, between 30 and 200 m deep. Individuals of current size (30-50 cm) are taken on the bottoms of 30 to 50 m. Large individuals catch on the line and long-line from 80 m depth. The species can reach 100 cm and 15 kg. It is known in the Mediterranean and on the Atlantic coast, from Portugal to Angola.
