Ants are social animals and live in colonies, sometimes these colonies may contain only 50 or so individuals but one supercolony of Formica yessensis on the coast of Japan is reported to have had 1,080,000 queens and 306,000,000 workers in 45,000 interconnected nests.

Some Scientist think that 30% of the animal biomass of the Amazon Basin is made up of ants, and that 10% of the animal biomass of the world is ants. and that a further 10% is Termites.
This means that 'social insects' could make up an incredible 20% of the total animal biomass of this planet.
