A group of squirrelfish (Holocentrus ascensionis) that are shoaling, not schooling: though swimming as a group, their speed and direction are not synchronised. This is a typical example of a marine population. [1]
Notes
The area that is used to define the population is such that inter-breeding is possible between any pair within the area and more probable than cross-breeding with individuals from other areas. Normally breeding is substantially more common within the area than across the border.
