In schools
Species that swim in coordinated groups.
What it means
A school is a group of fish or other aquatic animals moving together, often in synchronised manoeuvres in which each individual adjusts its position to that of its neighbours. Swimming this way reduces the risk of a predator singling out one individual, makes it easier to find food and, in some species, saves energy. Sardines, herring and many reef fish form some of the largest and most striking schools a diver can see.
