生物学特性     字汇 (例如 epibenthic)

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). Found schooling with other species having identical electric organ discharge (EOD) waveforms (Ref. 10460). A fractional spawner (Ref. 10605, 10606). Entomophagous (Ref. 51193).

具有电感受体布满整个头与在身体的腹而背部区域上, 但是发电器官所在的体侧与尾梗没有出现.(参考文献 10011) 被发现与有同一的发电器放电 (EOD) 波形的其他的种聚集成群。 (参考文献 10460) 一个少产的鱼种 (参考文献 10605; 10606)。
