Краткое описание определительные ключи | морфология | морфометрия
A giant skate with a broad-based, abruptly narrow-tipped snout covered with small, sharp thorns; pectoral disc angular, and no thorns on nape or back, but three rows of large thorns on tail (Ref. 5578). Larger immature and adult individuals grey with numerous small white spots above, underside white with no black pores; hatchlings plain reddish-brown above, often with blue spots, and white below with broad dusky grey margins on disc (Ref. 5578).
Inhabit shelf and slope waters (Ref. 4426). Found on sand and rock-sand bottom (Ref. 6808). A bottom-predator of bony fishes, other elasmobranchs, fish offal, crabs, shrimps, mysids, octopi, and cuttlefish (Ref. 5578). Minimum depth reported taken from Ref. 4426. Maximum length for female is 202 cm (Ref. 41333). 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 12.5-18.3 cm long and 10.0-13.9 cm wide (Ref. 41250). About 55-156 eggs are produced per individual annually (Ref. 41250).
Life cycle and mating behavior половая зрелость | размножение | нерест | икра | Fecundity | личинки
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Eggs are laid in huge cases and take up to 18 months to hatch (Ref. 5578). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).

Estimates based on models
Preferred temperature (Ref. 115969): 8.8 - 17.5, mean 13.5 (based on 474 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00269 (0.00231 - 0.00314), b=3.22 (3.18 - 3.26), in cm Total Length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278): 4.4 ±0.83 se; based on food items.
устойчивость к внешним воздействиям (Ref. 120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Fec=55).
Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
