(Phys.org)—A trio of researchers with the University of California's Department of Evolution and Ecology has found a predictable relationship between the size of predator fish mouths and the shape and spine characteristics ...
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 synchronize the movement ...
