The ghostly image of the Saharan cheetah has excited conservationists, as perhaps fewer than 10 of the cats survive in the deserts of Termit, Niger, where the photograph was taken.
Almost nothing is known of the Saharan cheetah, except that it endures extremely high temperatures and appears to survive without a permanent source of water.
Saharan cheetahs are thought to range in six countries: Algeria, Togo, Niger, Mali, Benin, and Burkina Faso.
But the total population may be fewer than 250 mature individuals.
The first ever camera trap photograph of one was only taken last year in Algeria.Follow the link to a pretty goulish photo
More than 50 cheetahs are thought to live there, compared to 10 or fewer in Niger.
