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 ...

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 ...

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 ...

Neuroscientist Nathan Sawtell has spent a lot of time studying a funky looking electric fish characterized by its long nose. The Gnathonemus petersii, or elephantnose fish, can send and decipher weak ...

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 ...

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 ...

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 ...
