Μέγεθος / Βάρος / Age

Maturity: Lm ?  range ? - ? cm
Max length : 80.0 cm WD αρσενικό/απροσδιόριστο; (Ref. 3169); common length : 65.0 cm WD αρσενικό/απροσδιόριστο; (Ref. 3169)

Βιολογία     Γλωσσάρι (π.χ. epibenthic)

Found over sandy and muddy bottoms. Feeds on bottom-living invertebrates and fishes. Ovoviviparous, gestation about 4 months and about 6 to 9 young are produced.

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

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 13.3 - 16.1, mean 14.9 °C (based on 33 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00265 - 0.01571), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Τροφικό Επίπεδο (Ref. 69278):  4.0   ±0.62 se; based on food items.
Ελαστικότητα (Ref. 120179):  Πολύ χαμηλό, ελάχιστος χρόνος για διπλασιασμό πληθυσμού > 14 έτη (Fec=6-9).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (78 of 100).
