Краткое описание определительные ключи | морфология | морфометрия

Snout white. Mouth nearly straight. Rostral ridges confluent, very narrow, with a small and short groove at base and with spines. Entire upper surface rough (Ref. 6902).

биология     глоссарий (например epibenthic)

Ovoviviparous (Ref. 50449). Size is based on original stuffed specimen, now in British Museum (Ref. 6902).

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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00145 - 0.00950), b=3.09 (2.87 - 3.31), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref. 120179):  низкий, минимальное время удвоения популяции 4.5-14 лет (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
