Latest Electroreception Stories
It sounds shocking, but the Tennessee Aquarium's Electric Eel uses his unique abilities to trigger his own Tweets.
Sharks are highly-evolved killing machines and a new study published in the open-access journal PLOS ONE has compiled a comprehensive picture of how these marine predators hunt – from start to finish.
In search of a better shark repellant, a marine biologist stumbled upon a behavior by embryonic sharks designed to evade predators sniffing around for lunch.
In 1997, scientists at the Center for Neurodynamics at the University of Missouri - St. Louis demonstrated that special sensors covering the elongated snout of paddlefish are electroreceptors that help the fish detect prey by responding to the weak voltage gradients that swimming zooplankton create in the surrounding water.
A new study finds that sharks, paddlefishes and certain other aquatic vertebrates have a sixth sense: the ability to detect weak electrical fields in the water, and to use this information to detect prey, communicate and orient themselves.
Bruce Carlson stands next to a fish tank in his lab, holding a putty colored Radio Shack amplifier connected to two wires whose insulation has been stripped.
Sharks are known for their almost uncanny ability to detect electrical signals while hunting and navigating. Now researchers have traced the origin of those electrosensory powers to the same type of embryonic cells that gives rise to many head and facial features in humans.
The Electric eel, Electrophorus electricus, is a species of fish. It is capable of generating powerful electric shocks, which it uses for both hunting and self-defense. It is a top predator in its South American range. Despite its name it is not an eel at all but rather a knifefish. Taxonomy The species is so unusual that it has been reclassified several times. Originally it was given its own family Electrophoridae, and then placed to a genus of Gymnotidae alongside Gymnotus....
The platypus is a semi-aquatic endemic to eastern Australia and Tasmania. Together with the four species of echidna, it is one of the five species of monotremes, the only mammals that lay eggs instead of giving birth to live young. It is the sole living representative of its family and genus, though a number of related species have been found in the fossil record. The unique appearance of this egg-laying, duck-billed mammal baffled naturalists when it was first discovered, with some...
