Many types of animals combine the advantages of family association with
those conferred by membership in
still larger groups. Bees congregate in
hives; some fish move in schools; ants gather in mounds;
wolves live in packs; deer
associate in herds. The main advantage
of membership in a mass community is the safety that it provides. A large group
of prey may be easier for a predator to find at any given point than is a
small one, and a predator may think twice before taking on such a group; if a
predator does decide to challenge a large group, it may merely encounter a
confusing mass of moving bodies and possibly may not succeed in its primary
goal.
