Scientists estimate that there are more than 20,000 species of ants. The species range in size from 1mm long to 38mm long and live in most environments.

Ants have been able to successfully inhabit so many different environments because their populations have been able to –

hybridize with other species of insects

adapt to a variety of habitats and food sources

fill niches occupied by mammals

occupy habitats that have no other life forms
