Army ant

Army ant
Genus: Eciton

Unlike most ants, which make long-term nests, army ants are migratory. They build temporary camps, or bivouacs, out of their own bodies. Using hooks at the end of their legs, worker ants link their legs together and create ant chains. These chains layered upon each other create a huge mass of ants, with the queen and larvae safely in the center. Army ants exhibit group predation and go on leaderless raids, swarming anything in their path. Not much stands a chance against these ants, unless it can move out of the way—the swarm averages a foot per minute. Even large mammals can fall prey to it if they are injured, tied up, or otherwise immobile.
