Optical illusion?

Sunday 20th August 2017 (1821)

When I got home at lunchtime I knew if I sat down I would fall asleep so I went straight out again for a therapeutic drive around Knowsley Safari Park. 

I wanted to see the new enclosure for the wolves. They weren't happy with their old accommodation next to the busy safari drive so they petitioned for a move. They have gone from the "inner city" to a large country manor on the foot safari and apparently they are much happier. Today, however, they were in hiding.

I liked this shot of the zebra as it is an optical illusion. Which body does the head belong to?

I have been invited out for a meal this evening so that will be nice and relaxing.
