From laughing donkeys and grimacing lions to a ‘headless’ penguin and a frustrated hippo, these hilarious images capture hapless animals pulling a range of funny faces.
Pictures taken all over the world by a number of photographers show a side of the animal kingdom many of us rarely see.
They include a gorilla picking its nose, a fox jammed head first in a snow drift and a stag blindly charging around with a clump of undergrowth covering its eyes.
There is even a flamingo with its legs in a twist and a hippo running away after being attacked by a small flock of birds.
