Affinities: P. pellegrini. Generates electric organ discharge (EOD) of short duration that seems to correlate with aggregative behavior of the species (Ref. 14060; 10601). EOD temporal pattern cues have been shown to play a role in species recognition for P. bovei (Ref. 10600). A ratio measure between olfactory and visual receptor areas suggests that this species relies more on visual than olfactory information (Ref. 10839). A fractional spawner (Ref. 10605; 10606).
分类相关: P. pellegrini. 产生发电器放电 (EOD) 持续很短的时间那似乎与此鱼种的集体行为互有关连 (参考文献 14060; 10601)。 EOD 时态信号曾经显示为 P. bovei 在种辨认扮演一个角色。 (参考文献 10600) 在嗅觉与视觉的感觉区之间的一个比例的测量显示出这种较信赖视觉的超过嗅觉的信息.(参考文献 10839) 一个少产的鱼种 (参考文献 10605; 10606)。
