Don't worry - your eyes are not deceiving you.These pictures are sheer animal magic as photographers around the world captured a series of optical illusions from the natural world.
In one of the pictures a giraffe appears to sprout a second head. The incredible image - that is actually of two giraffes sizing each other up before a fight - was captured by Scottish GP Steve Garvie while on safari in Kenya.In another shot from the UK some cows seem to be grazing on a bungalow roof. The bizarre photograph was taken in Newton Abbot, Devon, by snapper Ian Wilson.
