This photograph flawlessly captures two cheetahs standing ready and vigilant in the rays of another remarkable day in Tanzania. Distinctively the fastest moving land mammal, these incredible cats are capable of achieving speeds in excess of 70 mph (110 kph) in pursuit of prey.

The rhinoceros is critically endangered! Approximately 200 years ago, at the turn of the 19th century, there were an estimated one million rhinos. By 1970, the count was about 70,000. Today, there are fewer than 24,000 remaining in the wild. If there is no change in our appreciation of this magnificent animal – if we do not take action to stop poaching and support the protection of our rhinos – the five surviving species (white rhino, black rhino, Indian rhino, Sumatran rhino and Javan rhino) will become extinct in the wild in our lifetime.
