Title: Why do fish move in shoals?
Post by: joedeluco 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?
