The Satanic Leaf-Tailed Gecko has the greatest camouflage trick

To the less discerning eye, it could be a leaf shrivelling up on a tree fighting the onset of the first autumn chill

But this amazing form is in fact a lizard which can camouflage itself so well that it actually looks like a leaf

Perched on a branch, this Satanic leaf-tailed gecko has blended itself into its surroundings so expertly that even making out its coil-shaped body among the foliage is no mean feat

Its curvy body - at the top of the image - is only a slightly lighter hue of brown than the dark leaf it has tangled itself around

As your eyes move across to the right of the picture, you can just about see its torso making a single corkscrew movement as its darker brown tail tapers off to the right

To the left of the picture, the gecko's head can be seen as well as its left arm and left leg which squats under its body

Finally, Usain Bolt got competition!

Jamaican athlete Usain Bolt may think he's speedy afte

r breaking his own 100m world record last month. But he has nothing on Sarah the cheetah, who managed the feat in 6.13 seconds, compared to Bolt's 9.58 seconds at the World Championships in Berlin.

Like Bolt, the eight-year-old mammal managed to break her own record, after eclipsing her first time of 6.16 seconds on her second attempt. The spotted creature took to a specially designed 100m race course at at Cincinnati Zoo's Regional Cheetah Breeding Facility in America yesterday to take part in the run.

Her amazing time means she is now officially the fastest land animal.

She was so quick that she even caught up with the lure that was encouraging her to run. Sarah ran three times yesterday to claim the world record.

Her first run broke the record of 6.19 seconds with 6.16 seconds and her second run was even faster at 6.13 seconds. She ran the 100 meters in 6.33 seconds on her third run.
