A close-up of meerkat in the Kalahari Desert shows its sturdy, rakelike claws, an important adaptation for their tunneling lifestyle. Meerkats are master excavators, frequently digging themselves entirely out of sight in pursuit of potential meals, which include beetles, scorpions, insect larvae, and small reptiles.
