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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

The Euphanerops sported bizarre fins below its anus, revealing some of the odd turns evolution took on the path to vertebrate evolution A 370-milion-year-old, primitive fish sported a weird pair of ...
