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 ...

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).

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 ...

Neuroscientist Nathan Sawtell has spent a lot of time studying the electric elephantnose fish. These fish send and decipher weak electric signals,... The "shocking" tactic electric fish use to ...

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 ...

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 ...

Electric fish exhibit a highly specialised sensory modality that utilises self‐generated electric fields to navigate, forage and communicate in turbid aquatic environments. Their electrosensory ...

Nighttime drops in ocean oxygen raise energy use in small reef fish. Repeated stress could affect reef health as oceans warm.
