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 ...

Amphibious fish have evolved a remarkable suite of locomotory strategies that enable them to navigate both aquatic and terrestrial environments. These species exhibit a range of adaptations—from ...

Researchers at Northwestern University have identified a single mechanical ratio that dozens of unrelated sea creatures, from ...

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 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 ...

How can fish hover in the water, slowly swimming in place, but turn on a dime and dart away from predator? Aerospace engineer Michael Philen and his team at Virginia Tech are studying how a fish’s ...

‘A European academic consortium is to build a robot fish that can swim predictably in moving and turbulent water. Lead institute Tallinn University of Technology in Estonia, together with Riga ...

An EU-funded project has developed robot fish with lateral line sensing, a sensing organ common to fish with no technological counterpart in man-made underwater vehicles. In an article published in ...
