Tallest termite mound

Tallest termite mound
Nasutitermes triodiae
Not applicable

The tallest structures constructed by an animal (excluding humans) are the mounds of the eusocial insects termites (order Isoptera). These veritable skyscrapers of the animal kingdom are made from soil, plant matter and the saliva and faeces of the termites, forming a fortress-like structure that is impervious to most weather and predators. Some of the tallest documented examples are built by “cathedral termites" (Nasutitermes triodiae), native to grasslands in Australia's Northern Territory. Their lofty chimneys can reach 8 metres (26 feet) off the ground. Scaling the length of a termite up to the height of a human, the mounds are equivalent to four Burj Khalifa towers (the tallest building in the world at 829.8 metres/2,722 feet) stacked on top of each other. There are unconfirmed reports of a 12.8-m-tall (42-ft) mound in the Republic of Congo built by an African species known as the war-like termite (Macrotermes bellicosus) but evidence to ratify it is scant. Another particularly lofty one-off case, noted in the Guinness World Records archives, is an 8.7-m-tall (28.5-ft) termite mound that was photographed by a W Page south of Horgesia in Somalia in 1968.
