Mounds of the cathedral termites on the dry plains of the Northwest Territory dominate the landscape and often tower more than 15 feet in height.

[2][3] Constructed from mud, plant parts, and termite saliva and feces, the columns of the mound are extraordinarily tough and able to withstand the rigors of wind, rain, heat, and hungry predators.

Construction of the hollow columns allows for internal circulation of air from the cooler soil at the base of the mound to the warmer top.

This clever ventilation provides a central air-conditioning system that enables the colony to remain relatively cool even when the external temperatures are very hot.

[4] Termite soldier castes can be distinguished by their dark brown head and elongated, tubular snout called a nasus.
