Schools of forage fish often accompany large predator fish. Here a school of jacks accompany a great barracuda.

In biology, any group of fish that stay together for social reasons are shoaling (pronounced /ˈʃoʊlɪŋ/), and if the group is swimming in the same direction in a coordinated manner, they are schooling (pronounced /ˈskuːlɪŋ/). In common usage, the terms are sometimes used rather loosely. About one quarter of fish species shoal all their lives, and about one half shoal for part of their lives.
