Argentine ants

If you thought that humans had principal jurisdiction over the Earth, you may want to think again. It turns out that ants may have a more credible claim to world domination. In fact, scientists have recently discovered a single mega-colony of Argentine ants with a home range that nearly spans the globe, occupying lands as far reaching as Europe, the Americas and Japan.

The largest unbroken collective of this elephantine megacolony stretches over 3,700 miles along the Mediterranean coast.
