"Silent Swimmers: The Stealthy Advantage of Fish Schools"

Researchers from Johns Hopkins University have discovered that fish swimming in schools not only provides protection from predators but also reduces their noise, making them more stealthy. Using a 3D model based on the common mackerel, the team found that synchronized tail flapping among fish cancels out each other's sound, effectively reducing the acoustic signature of a school of fish. This noise reduction also enhances their swimming performance, allowing them to swim faster while using less energy. The findings shed light on the evolutionary brilliance of fish schooling as a defense mechanism.
