生物学特性     字汇 (例如 epibenthic)

Inhabits both still and flowing waters; breeds in the flood season; feeds on mollusks (Ref. 28714). Possesses electroreceptors over the entire head and on the ventral and dorsal regions of the body, but absent from the side and the caudal peduncle where the electric organ is located (Ref. 10011). Its electric organ discharge (EOD) is steroid-sensitive (Ref. 10763; 10764). Fecundity value of 18,924 eggs has been reported for this species (Ref. 10607).

栖息于静止的或流动的水域, 在洪水季节中繁殖。 吃软件动物。 (参考文献 28714) 具有电感受体布满整个头与在身体的腹与背部区域上, 但是发电器官所在的体侧与尾梗没有出现.(参考文献 10011) 它的发电器放电 (EOD) 是类固醇-敏感的 (参考文献 10763; 10764)。 产卵数目为 18,924个卵已经是这个种的报告。 (参考文献 10607)
