Fish

A:

According to North Carolina Aquariums, fish swim in schools because schooling protects them from predators, encourages reproduction and makes it easier to find food. Schooling also conserves energy, as each fish drafts in the wake of the fish ahead of him. This makes it easier for fish to swim long distances without exhaustion.
