Incredible images have emerged that shows a monkey appearing to give CPR to a 'wounded' member of its troop.
The vervet monkey looks like it is attentively trying to revive the stricken female by giving mouth to mouth resuscitation.
But he is in fact just taking advantage of an opportunity to groom the monkey while she is lying down.
Wildlife photographer William Steel took the astonishing photographs in the Gaborone Game Reserve in Botswana.
The 28-year-old said: "In what I can only describe as dramatic fashion, the female monkey fell to the floor, with both legs and arms spread out.
"At first, I couldn't figure out what was happening, but as I picked up my camera, another monkey came sauntering in grabbing the monkey on the floor by its mouth and seemingly administering CPR."
Mr Steel, who lives and works in the African nation, added: "On reflection, I think the performance was all a cry for attention from the female.
"There is a clear and important hierarchy in the troop, like humans this social community is largely based around 'if you scratch my back, I'll scratch yours'.
"Bonds are formed largely through grooming.
"I have often seen this extended to help clean wounds, and even nurse injured troop members.
"In my opinion, this compassion can sometimes be manipulated by attention-seeking individuals. It was an amusing moment to capture."
