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 ...

Along the murky bottom of the Amazon River, serpentine fish called electric eels scour the gloom for unwary frogs or other small prey. When one swims by, the fish unleash two 600-volt pulses of ...

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 ...

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 ...

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 ...

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 ...

Male fish can amp up their electric fields to woo females and intimidate rivals, research now reveals. A number of fish can generate electric fields. Relatively few such electric fish pack strong ...

Back in 2016, a scientist from Germany's University of Bonn discovered how the African elephantnose fish can switch between its visual and electrical sensory systems. Now, a team led by that same ...

Just as people plug in to computers, smart phones and electric outlets to communicate, electric fish communicate by quickly plugging special channels into their cells to generate electrical impulses, ...

In many, many ways, fish of the species Brienomyrus brachyistius do not speak at all like Barack Obama. For starters, they communicate not through a spoken language but through electrical pulses ...
