Tamaño / Peso / Age

Maturity: L_m ? range ? - ? cm
Max length : 50.0 cm TL macho / no sexado; (Ref. 41299)

Deep sea species. 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 3.6-3.8 cm long and 2.2-2.5 cm wide (Ref. 41249, 41253). Males at 31 cm TL still immature. Life history poorly known (Ref. 114953).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

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).

Estimates based on models

Preferred temperature (Ref. 123201): 7.3 - 13.5, mean 9.1 °C (based on 41 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00562 (0.00288 - 0.01097), b=3.11 (2.94 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.8 ±0.7 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
