school of fish
Synchronized underwater group
A school of fish is a group of fish swimming together in coordinated movement, often numbering in the hundreds or thousands.
The term emphasizes synchronized behavior—the fish turn, accelerate, and change direction as a unit: A school of fish darted beneath the boat.
School applies to fish specifically, while the broader term for animal groups is shoal.
