Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 140 cm TL male/unsexed; (Ref. 26346)

Short description Identification keys | Morphology | Morphometrics

Dark brown to grey in color (Ref. 26346). Juveniles covered with small prickles dorsally; adults smooth, thin-bodied and with a greatly elongated snout (Ref. 26346).

Biology     Glossary (e.g. epibenthic)

Adults inhabit the continental slope (Ref. 26346). 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 8.8 cm long and 4.7 cm wide (Ref. 41249).

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

Oviparous (Ref. 26346). 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 based on models

Preferred temperature (Ref. 123201): 5 - 9.5, mean 7.1 °C (based on 197 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00291 - 0.01038), b=3.13 (2.97 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.1   ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (84 of 100).
