Why Do Fish School?

The video explores the fascinating behavior of schooling fish, highlighting how they coordinate movements without a leader. It distinguishes between schools and shoals, explaining their benefits beyond predator avoidance, such as reduced metabolic rates and increased growth. The video delves into the role of psychology, physics, and fluid dynamics in schooling, showing how fish save energy. A 2020 study using robotic fish reveals how fish adjust tail beats to optimize energy use, demonstrating the advantages of schooling even without predators.
