The brain cells you see in the above image help an African fish decode electric signals to spot prey, scan its murky ...

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 ...

Electric organs help electric fish, such as the electric eel, do all sorts of amazing things: They send and receive signals that are akin to bird songs, helping them to recognize other electric fish ...

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 ...

When you hear the term ‘electric fish,’ the first thing that probably comes to mind is the infamous electric eel. It’s an aquatic animal capable of stunning nearby threats with a powerful electric ...

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 ...

Writing June 27, 2014 in the journal Science, a team of researchers led by Michael Sussman of the University of Wisconsin-Madison, Harold Zakon of the University of Texas at Austin and Manoj Samanta ...

To find buried prey, the elephantnose fish senses tiny electric fields while firing its own pulses. A brain map shows how neurons filter them out.

Electric fish pause before sharing something particularly meaningful. Pauses also prime the sensory systems to receive new and important information. The study reveals an underlying mechanism for how ...

The electric eel is one of the most startling animals in fresh water, able to deliver a jolt powerful enough to stun a horse ...

Electric eels generate up to 600 volts for hunting, defense, and navigation. Found in South American rivers, electric eels use electrocytes to produce shocks. Despite their name, electric eels are ...

A new study explains how small genetic changes enabled electric fish to evolve electric organs. The finding might also help scientists pinpoint the genetic mutations behind some human diseases.
