生物學特性     字彙 (例如 epibenthic)

Lives on the continental shelf, usually in very shallow waters. Feeds on invertebrates and benthic fishes. Ovoviviparous (Ref. 50449). Maturity size of males usually at ca. 40 cm TL (Ref. 114953). The electric organs can produce a discharge of about 45 volts, depending on the size of the animal. The discharge is used to stun prey and as defense against predators.

生活在大陸棚, 通常在很淺的水域。 吃無脊椎動物與底棲的魚。 卵胎生的.(參考文獻 50449) 發電器能生產被依據動物的大小而定的一個大約 45 伏特的放電。 放電被用來打昏獵物與如對抗掠食者的防衛。

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚

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).東太平洋: 哥斯大黎加 (參考文獻 9264) 與智利.(參考文獻 9068)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00659 - 0.03318), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  4.0   ±0.61 se; based on food items.
回復力 (Ref. 120179):  非常低的, 最小族群倍增時間超過14 年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High vulnerability (56 of 100).
Nutrients (Ref. 124155):  Calcium = 18.8 [3.8, 89.1] mg/100g; Iron = 0.691 [0.177, 2.037] mg/100g; Protein = 18.3 [13.9, 21.7] %; Omega3 = 0.428 [0.181, 0.942] g/100g; Selenium = 28.9 [9.4, 83.9] μg/100g; VitaminA = 11 [4, 34] μg/100g; Zinc = 0.562 [0.275, 1.039] mg/100g (wet weight);
