There are approximately 20 quadrillion ants in the world, which is about 20,000,000,000,000,000 individual ants. This estimate comes from a comprehensive global study analyzing ant populations across continents and habitats. The mass of all these ants combined exceeds that of all wild birds and mammals on Earth, representing about one-fifth of the total human biomass. This estimate is considered conservative since it does not fully account for ants living underground or in less-studied regions like Northern Asia and Central Africa.
