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 ...
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 ...
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 ...

Pretend for a moment, Barthelat explained, that fish fins are made up entirely of collagen. They could bend easily, but wouldn't give fish much traction in the water because hydrodynamic forces would ...

In the deep ocean, where sunlight never reaches, and food drifts down like confetti, survival is less about speed and more ...
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 ...
