وصف مختصر الوصف الخارجي | قياسات المظهر الخارجي

الأشواك الظهرية (المجموع): 0; شوكة شرجية 0; أشعه شرجية لينه: 0. Sub-rhomboid in shape with a short rostrum and rounded wing-tips. 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; with 1-2 thorns between dorsal fins; 2 equal-sized dorsal fins at end of tail. Brownish dorsally with numerous small dark spots which do not reach the margin of the disc, frequently with a concentration of dark spots forming a ring around a pale centre on hind part of each pectoral fin, underside white (Ref. 3167).

أحياء     المصطلحات (على سبيل المثال epibenthic)

Found mainly along the continental shelf (Ref. 3167). Depth range from 8-283 m in the northeast Atlantic (Ref. 82399), in the southern part of its range it occurs down to 530 m (Ref. 78469, 89037), but most common between 20-120 m (Ref. 88187). Prefers habitats with sand or mud bottoms (Ref. 78469). Juveniles usually found in shallow sandy inshore areas, adults utilize more offshore sand or sand-gravel habitats (Ref. 82399, 89038). Species buries itself to avoid predation and ambush potential prey. Feeds mainly on crustaceans (Ref. 3167) with prey size increasing as it grows (Ref. 88171), also preys on benthic worms, cephalopods and small fishes (Ref. 41849, 58137). Most individuals attain a length of 40-60 cm (Ref. 3261). Oviparous. Young may tend to follow large objects, such as their mother (Ref. 205). Detects weak electric fields generated by other organisms and generate its own weak electric fields (Ref. 10311).

Life cycle and mating behavior النضج | التكاثر | وضع البيض | بيض | الخصوبة | Larvae

Oviparous. Distinct pairing with embrace. Paired eggs are laid during summer (Ref. 3167). 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). Fully formed pups hatch after about 5-6 months and are about 11-12 cm in length (Ref. 78469, 88187).
