Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 0; колючие лучи анального плавника: 0. Snout pronounced, rather pointed; disc rhomboid, with angled outer corners upper surface entirely spinulose, underside prickly on large areas; about 8 thorns usually in a complete row around inner margin of eye, small thorns on scapular, generally a row of about 50 thorns on each side of midline from shoulder to first dorsal fin; upper surface plain ashy-grey, underside white (Ref. 3167).

биология     глоссарий (например epibenthic)

Found in relatively cold coastal waters and on upper parts of continental slopes (Ref. 3167). Most common at depths of around 200 m, but deeper in southern areas (Ref. 3167). Feed on all kinds of bottom animals, probably preferring fish (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 7.5-9.9 cm long and 4.5-4.7 cm wide (Ref. 41250). Maximum length for female is 111 cm (Ref. 41333).

Life cycle and mating behavior Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).
