Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼
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).東太平洋: 美國的南加州到祕魯。 記錄來自加拉巴哥群島了。 (參考文獻 5530) 在加拿大卑詩省的發生保持可疑。 (參考文獻 6885) 不在 Compagno's 1999 名錄中.(參考文獻 35766)

Estimates based on models
Preferred temperature (Ref.
123201): 12.1 - 21.3, mean 14.9 °C (based on 102 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [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): 3.5 ±0.50 se; based on food items.
回复力 (Ref.
120179): 低的, 最小族群倍增时间4.5 - 14 年 (Assuming fecundity<100).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (90 of 100).
Nutrients (Ref.
124155): Calcium = 17.9 [3.6, 84.2] mg/100g; Iron = 0.711 [0.182, 2.072] mg/100g; Protein = 23.3 [20.5, 25.9] %; Omega3 = 0.279 [0.080, 0.816] g/100g; Selenium = 29.2 [9.0, 83.0] μg/100g; VitaminA = 7.69 [2.88, 20.54] μg/100g; Zinc = 0.566 [0.279, 1.018] mg/100g (wet weight);
