Ant Brains (IMAGE) University of Arizona Caption In these scanning electron microscope images, the brain inside the head of a leaf-cutting ant is shown on the left. Its eyes are relatively small compared to those of the Australian bull ant (right). Known as an extremely aggressive species, bull ants possess extremely keen eyesight, which allows them to hunt prey over distances up to 3 feet.
