Cartoons that illustrate evolution depict early vertebrates generating primordial limbs as they move onto land for the first time. But new findings indicate that some of these first ambulatory ...

Fish that are bred to be bolder or more shy show corresponding changes to their body shape and locomotion, suggesting that personality changes affect other seemingly unrelated traits. The findings ...

A bio-inspired robot has been used to illustrate the mechanism by which some species of fish are able to walk on land, as reported in a Nature Communications paper. This demonstration may provide ...

Waves and eddies : effects on fish behavior and habitat distribution / Paul W. Webb, Aline Cotel and Lorelle A. Meadows -- Biomechanics of rheotactic behavior in fishes / R.W. Blake and K.H.S. Chan -- ...

Researchers have introduced an innovative underwater vest equipped with an antioxidant MXene hydrogel for the sensitive recognition of fish locomotion. This novel device aims to deepen our ...

There are about 28,000 species of bony fishes — the largest taxonomic group of vertebrates — and they have been around for a very long time (over 400 million years). So it’s no surprise that they have ...

A quirk of nature has long baffled biologists: Why do animals push in directions that don’t point toward their goal, such as the side-to-side sashaying of a running lizard or cockroach? An engineer ...
