Researchers have discovered the vast underground colonies where up to seven million of the insects live have their very own in-built ventilation shafts. Research has shown that the insects make specially-constructed turrets which ventilate the nests for optimum growth.
The ants carefully create the turrets with highly porous walls which allows air to flow through the chambers.
Leading the study, Dr Marcela Cosarinksy, from Buenos Aires’ Agentinian Museum of Natural Science told the BBC: ‘When [the ants] finished a turret, we analysed the arrangement of the building materials [under] the microscope.’
The ants construct the turrets by stacking sand grains and little balls of clay that they mould with their [jaws].’
