Diagnosis: upper surface almost smooth in young, but prickly in large specimens, except for bare centres of pectoral fins and hind part of disc; underside nearly smooth, except for narrow bands of prickles along front margins of disc and small patches in the gill region and on abdomen. Orbital thorns separate; a regular row of 20-50 usually persistent thorns from nape to first dorsal fin and 1-2 thorns between dorsal fins; thorns on lower edges of tail mainly in young. Colour: upper surface brownish with numerous small darker spots which do not reach the margins of the disc or of the pelvic fins; frequently a concentration of dark spots forming a ring around a pale centre on hind part of each pectoral fin (resembling an eye-spot) and occasionally several pale white blotches, underside white. Size: to about 80 cm TL.

Habitat: benthic, from inshore waters to about 100 m; moderately common, regularly marketed. Food: preference for crustaceans. Reproduction: oviparous; egg-cases laid in summer, embryos developing in 5-6 months, 64-77 by 37-46 mm (excluding horns).

Distribution: Atlantic coasts from Morocco northward to the Shetlands, southern North Sea and Baltic Sea, also western part of Mediterranean (to Tunisia and to western Greece).
