Marine Science / Why do fish move in shoals?
« on: 08/06/2010 12:12:57 »
Whenever I see footage of schools of fish they move in such complete unison. What prompts them to move as a group? When a predator approaches they all seem to dart in the same direction moving as one. Do they take their cue from a single fish or do they all respond individually and how is this communicated so instantly to the whole school?
