Why Do Fish School? The Energy Mystery Unveiled

Ever wondered why fish swim in groups, or schools? Scientists have been exploring this question using models that mimic fish. They've found that when fish swim side by side and move their tails at the same time, they actually save energy. But if one fish moves its tail differently, everyone ends up using more energy. In a line formation, fish at the back benefit from less effort, but only up to a point. After that, the group starts to break apart, and all fish suffer. This study reveals the fascinating link between group dynamics and energy use in fish. It also makes us ponder whether fish cooperate or compete when they're together. Would you believe that understanding fish schooling could even inspire new technologies? Indeed, learning from nature could lead to developments in robotics and ocean engineering that mimic this efficient energy use.
