Short description Morfologia | Morfometria

Spine dorsali (totale): 0; Spine anali 0; Raggi anali molli: 0. Rostral ridges widely separated over their entire length; anterior nasal lobe reaching to level of inner corner of nostril, posterior nasal flap wide; spiracle with two moderately developed folds, the outer one more prominent; thorns relatively small, present around inner margin of orbits, between spiracles, on shoulders, and along midline of disc and tail; Upper surface khaki-brown, underside white (Ref. 6675).

Biologia     Glossario (es. epibenthic)

Inhabits sandy and muddy bottoms, from the intertidal zone to about 100 m. Sometimes near rocky reefs (Ref. 12951). Slow swimming over bottom or partially buried. Feeds on benthic invertebrates, mainly crustaceans and small fishes. Males mature at ca. 56 cm TL, females at ca. 64 cm TL; born at ca. 25 cm TL (Ref. 114953). Ovoviviparous, one or two litters per year with 4-10 embryos.

Life cycle and mating behavior Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve

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). One or two litters per year, of 4-10 embryos (Ref. 6675)

Estimates based on models

Preferred temperature (Ref. 123201): 19.2 - 28, mean 26.1 °C (based on 104 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00204 (0.00164 - 0.00255), b=3.08 (3.01 - 3.15), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  4.1   ±0.5 se; based on diet studies.
Generation time: 8.2 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
