After a big rainstorm in the Kalahari (which softens up the earth), a colony of mole-rats can dig nearly a kilometre of new tunnels and shift nearly three tonnes of soil onto the surface above.
Bigger mole rats take on the soldier’s role of defence, while the smaller individuals act as workers and spend their days digging for edible tubers by sweeping the tunnels, tending to babies or cleaning the toilet chamber. Ninety-nine per cent of the colony will never reproduce. They can’t.
Typical individuals are 8 to 10 cm (3 to 4 in) long and weigh 30 to 35 grams (1.1 to 1.2 oz). Queens are larger and may weigh well over 50 grams (1.8 oz), the largest reaching 80 grams (2.8 oz). They are well adapted to their underground existence. Their eyes are quite small, and their visual acuity is poor.
