Yawning Cheetah, Okavango Delta, Botswana, 1999

The world's fastest land animal takes a moment to relax with a yawn on Botswana's Okavango Delta. The teeth of these fleet-footed predators are too small to use as daggers for large kill, but the cats have strong jaws that lock around the throat of prey until the victim stops breathing.

A trio of young African wild dog pups plays near a den in Botswana's Okavango Delta. Thought to be domesticated dogs gone feral, wild dogs have borne the brunt of extensive extermination programs. Today there are fewer than 5,000 wild dogs alive, which make them Africa's most endangered large carnivore.
