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 ...

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 fish exhibit a unique evolutionary adaptation that enables them to generate and perceive electric fields, providing a compelling model for exploring sensory ecology, neurobiology, and ...

A new study published in Science Advances explores the unique evolutionary processes among certain genes in certain fish species that allowed them to develop electric organs (think: the electric eel).

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 ...

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 ...

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 ...

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, ...

The electric eel is the closest thing nature’s got to a living, breathing battery. Running up to eight feet in length, these serpentine swimmers (which actually aren’t true eels, but a type of ...

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 ...
