(See ETYFish); crepidater: crepida (L.), low shoe (e.g., slipper); ater (L.), black, transliteration of Portuguese vernacular sapata preta, black shoe, allusion not explained, possibly referring to superficial resemblance to a black velvet slipper [see also Deania calceus, Centrophoridae]. (See ETYFish).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Anal spines: 0. Black or blackish brown in color, dorsal fins with very small fin spines, very long snout, greatly elongated labial furrows that nearly encircle mouth, lanceolate upper teeth and bladelike lower teeth with moderately long, oblique cusps, fairly slender body that does not taper abruptly from pectoral region, moderately large lateral trunk denticles with partly smooth, oval, cuspidate crowns in adults and subadults (Ref. 247).

A fairly common species found on continental and insular slopes (Ref. 6871), on or near the bottom (Ref. 5578). Feeds mainly on fish and cephalopods (Ref. 6871). Ovoviviparous (Ref. 205), with 4-8 young in a litter (Ref. 6871), born at 28-35 cm (Ref. 26346). The flesh is high in mercury; utilized as fishmeal and source of squalene (Ref. 6871).

Estimates based on models

Preferred temperature (Ref. 115969): 2.6 - 10.8, mean 7.8 (based on 659 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5313 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00181 - 0.00503), b=3.12 (2.98 - 3.26), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.4 se; based on diet studies.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Fec=4-8, tmax=54, tm=9-15).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (78 of 100).

Climate Vulnerability (Ref. 125649): Moderate vulnerability (38 of 100).

Price category (Ref. 80766): High.
