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 ...

The skeletal structure of a fish's gill arches and paired fins are quite similar – enough so that it was once believed the fins evolved from the arches. Although that theory has since been discounted, ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Research on fossilized fish details the evolution of fins as they began to transition into limbs fit for walking on land. Research on fossilized fish from the late Devonian period, roughly 375 million ...
