Краткое описание определительные ключи | морфология | морфометрия

Brownish-grey above, whitish below (Ref. 11228). Underside of pectorals with semicircular black blotch along middle of anterior edge (Ref. 11228).

Found in coastal and oceanic waters (Ref. 30573); solitary of aggregations, sometimes with 50 or more individuals (Ref. 90102). Not known to penetrate the epipelagic zone (Ref. 9911). Feeds on plankton (Ref. 30573). Ovoviviparous (Ref. 50449).

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

Preferred temperature (Ref. 115969): 25.6 - 29.1, mean 28.2 (based on 2136 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.

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 (85 of 100).
