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).東北大西洋: 已知只來自地中海了。 這種的有效性在 Compagno 1999 名錄懷疑了。 (參考文獻 35766)

Estimates based on models

Preferred temperature (Ref. 123201): 13.3 - 16.1, mean 14.9 °C (based on 33 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [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).
营养阶层 (Ref. 69278):  4.0   ±0.62 se; based on food items.
回复力 (Ref. 120179):  非常低的, 最小族群倍增时间超过14 年 (Fec=6-9).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (78 of 100).
Nutrients (Ref. 124155):  Calcium = 11.4 [2.2, 51.3] mg/100g; Iron = 0.269 [0.072, 0.742] mg/100g; Protein = 22 [19, 25] %; Omega3 = 0.532 [0.144, 1.564] g/100g; Selenium = 10.9 [3.1, 28.5] μg/100g; VitaminA = 11.5 [3.8, 33.6] μg/100g; Zinc = 0.407 [0.196, 0.714] mg/100g (wet weight);
