5 Wood Ants
Numerous animals live in colonies or groups, working for the benefit of one another. This is often true in insects, a well-known example of which is the hive of the honeybee. Ants are known for building mounds and living together, and they also exhibit behaviors that provide medicinal benefits to the entire colony.
Living in close-knit communities can increase the spread of diseases. Because wood ants are prone to pathogens, they use conifer resin in their nests to fight off parasites and other harmful microorganisms. This increases the health of the entire colony, like a human town agreeing to vaccinate their children to prevent the spread of disease. All the ants who use the resin-coated nests are less prone to infection.
