Short description Morphology | Morphometrics

A striking two-toned longnose skate, medium brown above and abruptly dark grey below, with a large, conspicuous, dark brown blotch on the upper base of each pectoral fin (Ref. 5578 ). Snout moderately elongated and bluntly triangular, and tail stout, not conspicuously swollen and about equal to body length; pectoral disc with broadly rounded corners and smooth underside without denticles; thorns at nape and along midline of back and tail to 1st dorsal fin, nape spine enormous in young (Ref. 5578 ). Hatchlings and juveniles with wide-spaced black spots on upper disc, inconspicuous or lost in adolescents and adults; adults sometimes with numerous small white spots (Ref. 5578 ). Underside with numerous black pores (Ref. 5578 ).

Biology     Glossary (e.g. epibenthic)

Found on soft bottoms of the outer shelf and upper slope (Ref. 5578 ). Feeds on bony fish, crabs, shrimp, mysids, mantis shrimp, euphausiids, bivalves and cuttlefish (Ref. 5578 ). Oviparous (Ref. 50449 ). Eggs have horn-like projections on the shell (Ref. 205 ). Males reaches maturity at 88-96 cm TL, females possibly slightly larger off Western than Southern coast of South Africa; hatching size at ca. 19 cm TL (Ref. 114953 ). Commonly taken by hake trawlers (Ref. 5578 ). Extremely slippery when caught (Ref. 5578 ).

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

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449 ). Eggs have horn-like projections on the shell (Ref. 205 ).

Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 9.2 - 16.7, mean 11 (based on 41 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00282 (0.00128 - 0.00621), b=3.24 (3.06 - 3.42), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  4.1   ±0.69 se; Based on food items. Resilience (Ref. 69278 ):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100). Vulnerability (Ref. 59153 ):  Very high vulnerability (75 of 100) .
