Australia’s carnivorous ants





                   7. How big is a meat ant nest?
                   Most nests are a metre or two wide

                   (between 3.2 and 6.4 feet), but some

                   colonies connect several satellite nests
                   together to make a ‘super-nest’. These

                   can stretch 650 metres (2,100 feet)!

              brave enough to eat
