If ants' vast array of abilities gives you pause, consider this: In many ways, they're the one animal outside the primate family that acts an awful lot like humans. And, like us, they've conquered nearly the entire planet.
Ants are native to every continent except Antarctica, but Argentine ants weren't content to live out their lives in South America. By hitching rides on planes, trucks, and ships, this group has spread across the world; they're seen here ripping a larger ant to bits.
Some scientists consider Argentine ants to be one giant super-colony spread across the globe. They will tear other species to shreds, but when ants from a colony in Argentina meet their brethren in Japan, the long-lost cousins get along swimmingly.
