A superorganism is an organism consisting of many organisms. The term is used most often to describe a social unit of eusocial animals, where division of labour is highly specialised and where individuals are not able to survive by themselves for extended periods.  Ants are the best-known example of such a superorganism, while the naked mole-rat is a famous example of the eusocial mammal. The technical definition of a superorganism is "a collection of agents which can act in concert to produce phenomena governed by the collective," phenomena being any activity "the hive wants" such as ants collecting food or bees choosing a new nest site. Superorganisms tend to exhibit the behaviours of homeostasis, power law scaling, persistent disequilibrium and emergent behaviours.
