While it is common for pet betta fish to lose fins, according to the experts, it is not normal. Either fin rot (which is caused by an infection) or fin loss (caused by external factors) could be the ...

The sensory system in fish fins evolves in parallel to fin shape and mechanics, and is specifically tuned to work with the fish's swimming behavior, according to new research. The researchers found ...

(CBS Detroit) --If you've caught a trout or salmon in Michigan with its adipose fin clipped, the state Department of Natural Resources (DNR) says it may have a tag with important information. Lake ...

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 ...

The cells that make fin rays in fish play a central role in forming the fingers and toes of four-legged creatures, one of the great transformations required for the descendants of fish to become ...

It's no big news that hands and feet evolved from aquatic fins. But when you look at a modern fish, it's hard to imagine just how how fins like theirs evolved into the hands, wrists and fingers that ...

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. Much of the ...
