(Fish move these structures by twitching sets of muscles located at the base of the fins). "If you look at a fin, you'll see that it's made of many stiff 'rays,'" said Barthelat, professor in the Paul ...

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, ...

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 ...

Researchers at Auburn University used wild-caught bluegills (Lepomis macro-chirus) in long-term behavioral studies. Bluegills (Fig. 1) are also commonly known as bream, blue bream, sun perch, blue ...

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 ...
