Fish schooling

Fish schooling is the behavior in which a group of fish swims together in the same direction in a highly coordinated way, each fish precisely spaced from its neighbors, distinct from the looser social grouping called shoaling. A school can perform complex, unified maneuvers that make it look almost as though the group shares a single mind. Schooling gives fish several advantages, including greater hydrodynamic efficiency that lets them swim faster while using less energy, better predator detection and a diluted individual risk of being caught, improved foraging success, and greater mating opportunity.
