The ability to move one's body rapidly through water is a key to existence for many species on this blue planet of ours. The Persian carpet flatworm, the cuttlefish and the black ghost knifefish look nothing like each other ...
Most animals use touch, smell, hearing, taste and sight to identify and attract a mate (that goes for humans too). But some species have additional and unusual weapons in their sexual armoury – the ability to sense vibrations ...
Scientists at the University of Massachusetts Amherst and the Instituto Nacional de Pesquisas da Amazônia (INPA), Brazil, this week report that they have discovered a new genus and species of electric knifefish in several ...
The weakly electric black ghost knifefish of the Amazon basin has inspired Northwestern University's Malcolm MacIver and an interdisciplinary team of researchers to develop agile fish robots that could lead to a vast improvement ...
As fish go, the lamprey has to be one of the most repulsive. Its eel-like body culminates in a tooth-encrusted sucker mouth straight out of a sci-fi horror film. Yet it turns out the lamprey, the most primitive of vertebrates, ...
The U.S. Naval Research Laboratory's (NRL) Acoustics Division, with Bluefin Robotics, executed a record setting 507 kilometer (315 mile), long-endurance autonomy research mission using its heavyweight-class mine countermeasures ...
A quirk of nature has long baffled biologists: Why do animals push in directions that don't point toward their goal, like the side-to-side sashaying of a running lizard or cockroach? An engineer building a robot would likely ...
Two very similar species of Amazonian electric fish share a key difference: One uses direct current (DC) and the other alternating current (AC), according to research that formally describes the two species for the first ...
A previously unknown genus of electric fish has been identified in a remote region of South America by a team of international researchers including University of Toronto Scarborough professor Nathan Lovejoy.
Much as human siblings can have vastly different personalities despite their similar resemblance and genetics, two closely related species of electric fish from the Amazon produce very different electric signals. These species, ...
