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

Found on continental slopes and deepwater rises (Ref. 3167). Oviparous. 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 5.3 cm long and 3.0 cm wide (Ref. 41249).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 3.3 - 5.2, mean 3.9 (based on 389 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00271 - 0.01168), b=3.13 (2.95 - 3.31), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.5 se; Based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 69278):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).
Verwundbarkeit (Ref. 59153):  Moderate to high vulnerability (46 of 100) .
