... by the distortions they cause in the electric field. The electrical properties of objects, their form and their distance,can be analysed and distinguished. Here we focus on Gnathonemus petersii (Günther 1862), an African fish of the family Mormyridae with a characteristic chin appendix, the Schnauzenorgan...

Terleph; Peter Moller SUMMARY African weakly discharging electric fish (Mormyridae) use their self-generated electric signals and electroreceptive abilities for orientation and communication in the context of courtship and territorial interactions. This paper documents socially mediated...

... Mormyridae individual recognition Pollimyrus isidori signature The mormyrid fishes of Africa produce weak electric discharges (EODs) with an electric organ in the tail. EODs are detected with a distributed array of electroreceptors on the body surface, and EODs function in communication arid...

...James H. Schluger; Carl D. Hopkins ABSTRACT African electric fish of a pulse species, Brienomyrus brachyistius (Mormyridae), housed singly in a large, circular arena, were presented with electrical stimuli which mimicked a conspecific intruder. Stimuli were produced with either dipolar or bipolar...
