Some subterranean ant species are blind. Others have eyesight ranging from poor to excellent. The Australian bulldog ant is able to gauge the size and distance of objects up to almost a meter away.
Many tiny lenses make up the compound eyes of ants. Ant heads also have three small simple eyes to detect polarization and light levels.
Ant antennae act as feelers, detecting currants, vibrations and chemicals, and they can also act as signal transmitters. An ant uses its strong jaw to carry food, build nests and manipulate objects. Some species are equipped with a small mouth pocket that they use to transfer food to other ants and larvae.
