Biology     Glossary (e.g. epibenthic)

Occur in the sublittoral zone, 30-100 m on sandy mud bottom (Ref. 11230 ). 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 6.5 cm long and 4.0 cm wide (Ref. 41249 ). FB name from Ref. 10932.

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

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449 ). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205 ). Egg capsules are 6.5 cm long and 4.0 cm wide (Ref. 41249 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 9.7 - 21.9, mean 18.4 °C (based on 144 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.8   ±0.6 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 ):  Moderate to high vulnerability (50 of 100).
