Biologie     Verklarende woordenlijst (bv. epibenthic)

Found on deeper continental slopes and probably abyssal plains, mainly deeper than 1,400 m (Ref. 3167). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). It is caught as by-catch in low numbers by deep trawl fisheries (Ref. 117245).

Estimates based on models

Preferred temperature (Ref. 123201): 3.4 - 6.6, mean 5.4 °C (based on 13 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.3   ±0.45 se; based on food items.
