Legs and feet: Front legs and feet are flat and shovel like which helps them dig their burrows, back legs and feet are elephantine.

No webbing is present between toes.

Three key requirements:
1. Dry upland habitat with sandy, well drained soils for ideal burrowing and nesting.

2. Open tree canopy so that plenty of sunlight reaches the ground.

Many share the burrow with the tortoise or use abandoned burrows.

Used to regulate body temperature and as shelter from predators and wildfires.

Up to 50ft (15 m) long and 15ft (5 m) deep, depending on water table. Width is about the length of the tortoise.

Aron (or Mound) in front of the burrow is often used as nesting site.
