Shoal
collective noun /ʃəʊl/ — What you call a group of fish — thousands of individual decisions moving as one.
Definition
A large group of fish swimming together. A shoal refers to fish gathered socially; a school refers specifically to fish moving in coordinated formation. Both terms are widely used interchangeably.
Beyond the definition
Watching a shoal of fish move in an aquarium or coral reef is one of nature's quiet hypnotic experiences. Thousands of individual decisions producing a single fluid organism. Shoal captures the shallow-water, sunlit image of this — light on scales, movement like thought.
Origin & history
From Old English scolu — a multitude, a troop. Related to 'school' (Dutch school — a crowd). The word also means a shallow area of water — fish shoals were often observed in the shallows near shore.
