- A school of fish moves in the direction of food.
While swimming, the fish eat and breed.
- The number of children produced in each generation, and their strength
depend largely on the amount of food that is found.
- The school may split up into parts, when food is found in different
directions.
- Fish (individual or parts of the school) that go of into a direction with
little or no food will die of starvation.
- Fish that enter polluted waters also die.
A school of fish also tends to move forward, and not go in small
circles. This is like a depth-first search foor food.
