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 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 ...

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 ...

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 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, ...

Flying fish, for example, deploy their fins to glide above the water, while mudskippers use their fins like legs to walk on land. "We like to pick up where the biologists and zoologists have left off, ...

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 ...
