Schooling fish, or fish schooling? Hummm
Schooling of fish has very little to do with their education. It does have much to do with their ability to survive and reproduce in sufficient numbers. Schools are composed of many fish of the same species moving in more or less harmonious patterns throughout the oceans.
Aristotle, over 2,400 years ago, observed this behavior in fish. Perhaps he sparked the interest humans have had in this fascinating trait of certain fishes.
