Short description

Dorsal spines (total): 0; Anal spines: 0. Upper surface almost smooth in young, but prickly in large specimens, except for bare centers of pectoral fins and hind part of disc, underside nearly smooth; orbital thorns separate, a regular row of 20-50 usually persistent thorns from nape to first dorsal fin; upper surface brownish with numerous small dark spots which do not reach the margins of the disc, frequently a concentration of dark spots forming a ring around a pale centre on hind part of each pectoral fin, underside white (Ref. 3167).

Found in shelf waters to about 100 m (Ref. 3167). Depth range from 20-120 m, and from 318-345 m in the eastern Ionian Sea (Ref. 56504). Feed mainly on crustaceans (Ref. 3167). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 5.3-7.8 cm long and 3.0-5.0 cm wide (Ref. 41250). About 24-60 eggs are laid by an individual in a year (Ref. 41250).
