Etymology: Parmaturus: parma (L.), from parme (Gr.), small shield; oura (Gr.), tail, presumably referring to upper edge of caudal fin “armed with modified” scales (per Garman 1913). (See ETYFish);  xaniurus: xanion (Gr.), comb for carding wool; oura (Gr.), tail, referring to crest-like row of tooth-like projections along upper edge of caudal fin. (See ETYFish).

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

Found on the outer continental shelf and upper slope. Feeds on a variety of small fish (e.g. lanternfish) and invertebrates. Oviparous. Possesses an enlarged gill region which is an adaptation to areas with low dissolved oxygen levels. Has a high concentration of squalene in its liver which affords it neutral buoyancy. Regularly caught by bottom trawlers but not utilized at all.

Estimates based on models

Preferred temperature (Ref. 123201): 6 - 14.9, mean 7.9 °C (based on 29 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00160 - 0.00498), b=3.08 (2.92 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.0 se; based on diet studies.
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (42 of 100).
