Yellow perch are poor swimmers. As a result, these creatures swim in schools of 50–200 fish to protect themselves from predators. Fish very well may have schooled before the Fall of man, but not for defensive reasons. The sheer beauty of a school of fish is reason enough for God to have created this way.
