Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 0; колючие лучи анального плавника: 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).

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 Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки

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. 115969): 19.2 - 28, mean 26.1 (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.

устойчивость к внешним воздействиям (Ref. 120179): низкий, минимальное время удвоения популяции 4.5-14 лет (tmax=5; Fec=4).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (66 of 100).

Категория цены (Ref. 80766): Low.
