Researchers from Tohoku University have developed a model that simulates the motion of fish tail fins. The model uncovers the underlying mechanisms behind a commonly observed phenomenon in fish: how ...

They say two heads are better than one. But in the world of fish, it appears two fins are better than one. Researchers have produced a theoretical model that demonstrates the underlying mechanisms ...

Swimming in schools makes fish surprisingly stealthy underwater, with a group able to sound like a single fish. The new findings by Johns Hopkins University engineers working with a high-tech ...

Water flow around the fins of a fish intertwines in a pattern that maximizes swimming efficiency. As fish wriggle, they create a complex push–pull pattern in the water that propels them forward. Many ...
