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 ...

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 ...

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 ...

Many fish species evolved parts of their fins into sharp, spiny, needle-like elements -- called fin spines -- that function to protect the fish against predators. Such spines have evolved ...
