Max length : 41.8 cm WD hane/ej könsbestämd; (Ref. 34976)

Occurs in shallow coastal waters (Ref. 7445). Almost with certainty to occur deeper than 20 m (Ref. 114953). Ovoviviparous (Ref. 50449).

Life cycle and mating behavior Maturities | Reproduktion | Spawnings | Egg(s) | Fecundities | Larver

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): 17.2 - 24.8, mean 21.3 °C (based on 62 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [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).

Trofisk nivå (Ref. 69278): 3.7 ±0.5 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
