Biology     Glossary (e.g. epibenthic)

Found in deepwater on lower parts of continental slopes, on submarine rises and on deep-sea plains adjacent to both (Ref. 3167 ). Feeds mainly on fishes, with a small amount of shrimps (Ref. 3167 ). Oviparous (Ref. 50449 ). Eggs have horn-like projections on the shell (Ref. 205 ). Minimum depth reported taken from Ref. 3167.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous (Ref. 3167 ). Paired eggs are laid. Embryos feed solely on yolk (Ref. 50449 ). Eggs have horn-like projections on the shell (Ref. 205 ).

Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 3.6 - 6.1, mean 4.3 (based on 43 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00490 (0.00244 - 0.00981), 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 ):  4.0   ±0.69 se; Based on food items. Resilience (Ref. 69278 ):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100). Vulnerability (Ref. 59153 ):  Very high vulnerability (86 of 100) .
