This red coated Orangutan climbed the net of which the walls of his cage are made. The photo was taken in the zoo of Gelsenkirchen (ger.: Zoom Erlebniswelt Gelsenkirchen).
I usually try to photograph zoo animals in a way so that it is not apparent that the photos show animals in captivity. In the case of this ape however, the white net as well as the metal structures in the background underline the unnatural character of being imprisoned and match the general theme of the picture.
