Μέγεθος / Βάρος / Age

Maturity: L_m ? range ? - ? cm
Max length : 70.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 555); 62.3 cm TL (female)

Holotype taken from a depth between 405-420 m (Ref. 26282). 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 6.7 cm long and 4.7 cm wide (Ref. 41249).

Life cycle and mating behavior Maturities | Αναπαραγωγή | Spawnings | Egg(s) | Fecundities | Προνύμφες

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. 115969): 1.2 - 3.8, mean 1.7 (based on 95 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00231 - 0.00625), b=3.08 (2.94 - 3.22), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Τροφικό Επίπεδο (Ref. 69278): 3.9 ±0.7 se; based on size and trophs of closest relatives

Ελαστικότητα (Ref. 120179): Χαμηλό, ελάχιστος χρόνος για διπλασιασμό πληθυσμού 4,5 - 14 έτη (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100).
