Segmented hinges in the long, thin bones of fish fins are critical to the incredible mechanical properties of fins, and this design could inspire improved underwater propulsion systems, new robotic ...

Newswise — The human fingertip is a finely tuned sensory machine, and even slight touches convey a great deal of information about our physical environment. It turns out, some fish use their pectoral ...

Peer into any fishbowl, and you’ll see that pet goldfish and guppies have nimble fins. With a few flicks of these appendages, aquarium swimmers can turn in circles, dive deep down or even bob to the ...

When designing a large underwater robot that could swim silently to avoid startling sea creatures, roboticist Rob Shepherd considered the unusual swimming system of oarfish, the meters-long fish whose ...

Limbs can be incredibly useful. Whether it’s the wing of a bat, the elongated leg of a hopping frog or our own grasping arms, limbs have been adapted to all sorts of ecosystems and functions through ...

New research finds some fishes' fins are as sensitive as the primates' fingertips, reports Carolyn Wilke of Science News. “We think about primates as kind of special in the sense that we have really ...

Pizza enthusiasts know well that a simple u-shaped curvature at the crust can keep a thin slice from drooping over when lifted from a plate. A team of engineers from Brown University has shown that ...

In the same way we might curve a piece of pizza at the crust to keep a thin slice from drooping, fish curve their fins slightly to stiffen them for swimming and control their movement underwater.

The human fingertip is a finely tuned sensory machine, and even slight touches convey a great deal of information about our physical environment. It turns out, some fish use their pectoral fins in ...
