Small but mighty insects, ants live on all continents except Antarctica, though they favour moist tropical regions. There are around 2.5 million ants for every human on earth and over 12,000 known species with thousands more yet to discover. They are eusocial insects that live in complex societies and communicate using pheromones. They work together to get jobs done.
Eusocial animals live in large groups in which only one female but several males produce offspring. Non-reproductive individuals look after the young.
In a eusocial society, individuals are divided into groups called castes, with each caste performing a different role within the colony.
