Biologi     Daftar kata (contoh epibenthic)

This species lives in deep waters, on the upper continental slope and often over fine sediment; reported to have a preference for colder temperatures than its congeners. The size at maturity for males is from 109 to 120 cm TL, for females 145 cm TL; size at birth uncertain, with the smallest free-swimming specimen measured 19 cm TL. Feeds on annelids, cephalopods, crabs, shrimps, and bony fishes, the smaller individuals consume more invertebrates (Ref. 126515). 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). The light golden brown egg cases are large (10.8-11.1 cm TL), with coarse surface due to the rasp-like denticles; with a distinct groove between the lateral keel and the case (absent in all other ENP skate egg cases) and with horns at the corners, the anterior horns more robust than posteriors, with both sets becoming flat and thread-like at tips (Ref. 126515).
