Kurzbeschreibung Morphologie | Morphometrie

Disk without spines, except near edge of pectoral fins in males. Ventral mucous pores not blackish. Tail with middorsal row of large spines. Snout pointed (Ref. 7251). Upper surface pale brown or bluish gray without dark markings. Lower surface white with small sooty blotches irregularly distributed around margins of pectorals, pelvic fins white below. Lower surface of tail white but pale brown rearward (Ref. 6902).

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

An inhabitant of deep, cold water (Ref. 7251). Benthic (Ref. 58426). Feed on all kinds of bottom animals (Ref. 3167). Oviparous (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 13.4-16.5 cm long and 8.0-10.2 cm wide (Ref. 41251, 41301).

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

Oviparous (Ref. 3167). Paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 0.3 - 7.6, mean 2.5 (based on 411 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00240 - 0.00999), b=3.13 (2.96 - 3.30), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.4   ±0.6 se; Based on diet studies.
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).
Verwundbarkeit (Ref. 59153):  Very high vulnerability (86 of 100) .
