Who leads a school of fish?

School of fish


In a fish school, all the fish seem to behave alike and each school whether mackerel, herring, tuna, or small shiners resembles other schools in shape and form.

Of the many features schools have in common, the most surprising, perhaps, is the absence of a continual leader.

A school may swerve to the right or to the left, fan out from the center, or change direction entirely.

Each time, a different group of fish heads the school.

As these movements of the school as a whole are made, there is also constant movement within the school as each fish maintains its distance from the other fishes.

The precision of orientation that is shown by the fish as they swim in a school is amazing.
