The antennae of desert ants help them navigate by detecting odors stereoscopically.

Edit Hook


"Desert ants in Tunisia smell in stereo, sensing odours from two different directions at the same time.

"By sniffing the air with each antenna, the ants form a mental 'odour map' of their surroundings.

"They then use this map to find their way home, say scientists who report the discovery in the journal Animal Behaviour.

"Pigeons, rats and even people may also smell in stereo, but ants are the first animal known to use it for navigation." (Walker 2010)
