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 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 ...

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 ...

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

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 ...

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 ...

To answer how animals made the transition from sea to land, scientists have traditionally looked to the fossil record. But in the past 30 years, scientists have searched for changes in genes that can ...
