Short description Morphology | Morphometrics

an all-dark longnose skate with an elongated, acutely triangular snout, and a stout tail - shorter than body and with mid-section swollen sausage-shaped; disc with narrowly rounded outer corners and smooth underside except for small denticles on snout; no thorns on nape or along back (Ref. 5578 ). Dark brown with irregular dark blotches dorsally; rear end of disc and pelvic fins blackish; underside dark brown with black pores and scattered lighter blotches on disc, at base of pelvic fins, around vent, and on tail (Ref. 5578 ).

Biology     Glossary (e.g. epibenthic)

Occurs in deeper slope waters (Ref. 4426 ). Feeds on benthic fishes, shrimps and crabs (Ref. 27637 , Ref. 114953 ). Oviparous (Ref. 50449 ). Eggs have horn-like projections on the shell (Ref. 205 ). Males reaches maturity at ca. 101 cm TL (Ref. 114953 ).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 6.3 - 11.8, mean 7.3 °C (based on 17 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.8   ±0.66 se; based on food items. Resilience (Ref. 120179 ):  Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100). Fishing Vulnerability (Ref. 59153 ):  High to very high vulnerability (69 of 100). Price category (Ref. 80766 ):   Medium .
