The bodies of some honey ants are used for liquid storage via their expandable abdomen.


"In Australia, the honeypot ants collect nectar and force-feed it to workers of a special caste until their abdomens are distended to the size of peas and their skins stretched so thin that they are quite transparent. The workers then hang them up by their forelegs in underground galleries, like living storage jars." (Attenborough 1979:104)
