Certain ants in South and Central American rainforests will lie down in the potholes that stand between their army and food. Their bodies form a makeshift bridge, allowing other ants—sometimes numbering over 200,000—to make better time in getting to the source of nourishment.

This pattern in the life of ants was discovered through research done at England's University of Bristol. Researchers took a wooden plank and drilled different sized holes in it, simulating a narrow trail. Ants would find holes equal to their size and lay down inside, letting others walk safely over them. When the raiding party accomplished its mission and was returning to its nest, the faithful few climbed out of their holes and followed the raiders home.
