Μέγεθος / Βάρος / Age
Maturity: Lm ?  range ? - ? cm
Max length : 90.0 cm TL αρσενικό/απροσδιόριστο; (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
Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Αβγά | Γονιμότητα | Προνύμφες
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).
