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 ...

Fish fins are touch sensors, and they work in a way that’s similar to our fingertips. According to new findings published in Proceedings of the Royal Society B, the pectoral fins located behind the ...

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 ...

It's no big news that hands and feet evolved from aquatic fins. But when you look at a modern fish, it's hard to imagine just how how fins like theirs evolved into the hands, wrists and fingers that ...

A few hundred million years ago, fish fins morphed into the arms and legs of terrestrial animals, according to evolutionary theory. So, you’d think science would know just about everything about them ...

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 ...

Fish fins aren’t just for swimming. They’re feelers, too. The fins of round gobies can detect textures with a sensitivity similar to that of the pads on monkeys’ fingers, researchers report November 3 ...

Scientists believe that many millions of years ago, our aquatic ancestors made the leap from inhabiting the oceans to living on dry land, marking the evolution of the first four-limbed vertebrates ...

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 ...
