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 ...

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, ...

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 ...

WASHINGTON (Reuters) - Inside the stout fins of a fish that prowled the shallow waters of an estuary in what is now eastern Canada about 380 million years ago, scientists have found what they call 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 ...

Dec. 31 (UPI) --Before early marine species could make the transition to land, they had to develop tools for getting around out of the water. They needed limbs. Now, thanks to the discovery and study ...

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, ...

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 ...

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 ...
