Kurzbeschreibung Morphologie | Morphometrie

Diagnosis: Distinguished by the following characters (vs. Galeus antillensis): shorter prepectoral length 16.1%-18.6% (vs. 19.4-21.8%); smaller pectoral anterior margin (8.9-10.1% (vs. 10.2-12.7%); smaller pectoral posterior margin 7.4-8.5% (vs. 8.8-11.6%); and fewer number of diplospondylous vertebrae 35-36, n=3 (vs. 39-78, n=4) (Ref. 56495).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

The species inhabits deep-reefs in the shelf break and on the continental slope, and is often found in depths greater than 400 meters, with gorgonians, hard corals, tube sponges, crinoids, ophiuroids, and a great number of the sympatric scyliorhinid shark Scyliorhinus haeckelii (Ref. 56495). Minimum depth from Ref. 58018.

Estimates based on models

Preferred temperature (Ref. 115969): 11.6 - 15.8, mean 14.6 °C (based on 15 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00148 - 0.00675), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.9   ±0.2 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Fec= 1).
Verwundbarkeit (Ref. 59153):  Low to moderate vulnerability (33 of 100) .
