The brown ghost knifefish (Apteronotus leptorhynchus) generates a weak electric field that it uses to detect obstacles and to communicate with other knifefish. When confronting a rival knifefish, both ...

Fish that use electric fields to sense their environments dim their signals to save energy during the day when they are resting. Sternopygus macrurus, a South American river fish, is a natural ...

The elephant-nose fish Gnathonemus petersii relies on electricity to find food and navigate through the obstacles riddling its native murky African rivers. On July 11 in the journal Neuron, Columbia ...

Evolution has bequeathed to the glass knifefish some nifty talents. With an elongated ribbon fin that runs nearly the length of its body, the fish hovers, moves forward, and reverses using a subtle ...

Having a set of extra genes gave fish on separate continents the ability to evolve electric organs, report researchers from The University of Texas at Austin. Dr. Harold Zakon and colleagues, in a ...

Despite nearly indistinguishable outward physical appearances, the electric discharge signals of two newly discovered species of closely related fishes are quite different. Both electric fish belong ...

When listening to a well-practiced speaker, like during a lecture, a political event or during a favorite public radio show, you may notice they use pauses for dramatic effect. This type of nuance in ...

The elephant-nose fish Gnathonemus petersii relies on electricity to find food and navigate through the obstacles riddling its native murky African rivers. Researchers have presented evidence that the ...
