Electric communication fish
Electroreception and electrogenesis are the closely-related biological abilities to perceive electrical stimuli and to generate electric fields. Both are used to locate prey; stronger electric discharges are used in a few groups of fishes to stun prey. The capabilities are found almost exclusively in aquatic or amphibious animals, since water is a much better conductor of electricity than air. In passiv… WebApr 11, 2024 · Steroid hormones remodel neural networks to induce developmental or seasonal changes in animal behavior, but little is known about hormonal modulation of sensorimotor integration. Here, we investigate hormonal effects on a predictive motor signal, termed corollary discharge, that modulates sensory processing in weakly electric …

We hypothesized that the EOD also facilitates assortative mating and ultimately promotes prezygotic reproductive isolation in African weakly electric fishes.
WebAn electric fish is any fish that can generate electric fields. Most electric fish are also electroreceptive, meaning that they can sense electric fields. ... Many electric fishes also use EODs for communication, while … WebAlthough predation is commonly considered a force that simplifies communication signals, electric fish provide an example for which predation likely enhanced signal complexity. In wave-type gymnotiforms, EOD frequency appears to have increased during evolution. The evolutionary relationships among electric fish are still the subject of debate ...
WebAn important consideration, however, is the total duration of signaling in a 24-h period. In electric fish, communication signals are coupled to an active sensory system and are therefore emitted 24 h per day, unlike other expensive acoustic or mechanical signals that are emitted only for brief periods.
