Ecología
marino demersal; rango de profundidad 0 - 700 m (Ref. 106604). Subtropical; 10°N - 40°S, 95°W - 70°W (Ref. 114953)
Eastern Pacific: From Costa Rica to Chile, and Galapagos Is. (Ref. 130539).
Tamaño / Peso / Age
Maturity: Lm ?  range ? - ? cm
Max length : 90.0 cm TL macho / no sexado; (Ref. 114953)
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.
Life cycle and mating behavior
Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
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): PD
50 = 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).
Nivel trófico (Ref.
69278): 4.0 ±0.61 se; based on food items.
Resiliencia (Ref.
120179): Muy bajo, población duplicada en un tiempo mínimo superior a 14 años (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): High vulnerability (56 of 100).
Nutrients (Ref.
