Peccaries (javelinas) live in herds of up to 100 (possibly over 100 for white-lipped peccaries) individuals. Living in herds brings security in that predators will not charge into a group of prey; they must separate one from the group. Also, if a predator gets too close, a peccary may rub its tusks together in warning. If the predator does not go away, it may even hit it with its tusks.
