Like human beings, ants can be both cooperative and aggressivetowards one another; in fact, certain species of ants survive by raiding
other ant colonies and enslaving the offspring. Scientists believe that
these “slavemaker” ants cannot survive on their own and need other ants
to take care of them. The only way in which they can achieve this is by
raiding other colonies and seizing the larvae and pupae; they then carry
them back to their own colonies and raise them as slaves. Once their
slaves die, they raid new colonies, capture new larvae, and acquire a new
supply of slaves.
