Cool Facts About Ants
The world's biggest ant colony was discovered in 2002. This supercolony has billions of ants living in millions of nests. It stretches 3,600 miles, all the way from Italy to northwest Spain.
An ant can lift 50 times its own weight--which is as much of a feat for them as lifting a car would be for you!
Ants don't have lungs. They breathe through tiny holes in their sides called spiracles.
Ants display many behaviors similar to ours. For example, worker ants take care of larvae by feeding and washing them.
No one knows whether ants "sleep" in the way we do. They don't have eyelids, so they can't close their eyes. They do rest, but trying to monitor their brain activity at this time would interfere with it so much that the results wouldn't tell us anything. Ants do look for food only during the day. And in the winter, their breathing and metabolism slows way down.
