Southeast Pacific: Chile (Ref. 27540). Southern Ocean: around South Georgia Island and on the ridge westward towards Black Rocks. Occasionally seen on the Scotia Ridge.

Biology     Glossary (e.g. epibenthic)

Utilized as fishmeal and possibly not utilized for human consumption due to extreme roughness of its squamation (Ref. 5159). 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 capsule measures 116.5 mm long and 80.0 mm wide (Ref. 41249).

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

Oviparous, 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). Eggs have horn-like projections on the shell (Ref. 205).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00135 - 0.00677), b=3.21 (3.03 - 3.39), based on LWR estimates for this (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Assuming tm>5).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (54 of 100) .
Price category (Ref. 80766):   High.
