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 ...

It would be a game-changer if all members of a basketball team could see out of each other's eyes in addition to their own. Biologists have found evidence that this kind of collective sensing occurs ...

Bats and dolphins emit sound waves to sense their surroundings; like a battery, electric fish generate electricity to help them detect motion while burrowed in their refuges; and humans use tiny ...

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 ...

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 ...

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 ...

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 ...

Electrophorus voltai, a newly discovered species of electric eel, pictured swimming in the Xingu River, a southern tributary of the Amazon. L. Sousa Electric eels are hard to miss. They’re eight feet ...

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.
