Orphaned gorillas pose with their carer in the Democratic Republic of Congo
And these pictures appear to prove that, much like modern humans, apes enjoy posing for a selfie.
The snaps were taken by Patrick Sadiki Karabaranga, 39, who is the guardian of orphaned gorillas in Virunga national park in Rumangabo, Democratic Republic of Congo.
The kind-hearted warden has been looking after the animals for more than a decade and said he cares for them as if they are his children.
Among the hilarious photos illustrating his close bond, one cheeky gorilla is seen striking a serious pose as it stares into Mr Karabaranga's camera while sitting closely alongside him.
In another, a younger gorilla clutches a tennis ball as it enjoys a piggy-back ride with Mr Karabaranga.
A third gorilla doesn't appear to mind being caught picking its nose as its friend appears to pose with its thumb in the air.
Mr Karabaranga said: 'I think it's the curiosity to see themselves on the phone that entices them to take selfies with me.
