Two gorillas have been caught "posing" for a selfie, apparently imitating human behaviour, with the rangers who rescued them as babies.
The image was taken by ranger Mathieu Shamavu at a gorilla orphanage in Virunga National Park in Democratic Republic of the Congo, where the animals were raised after poachers killed their parents.
It went viral after being shared 20,000 times on Facebook.
"We want to emphasise that these gorillas are in an enclosed sanctuary for orphans to which they have lived since infancy," the post said.
"The caretakers at Senkwekwe take great care to not put the health of the gorillas in danger. These are exceptional circumstances in which the photo was taken. It is never permitted to approach a gorilla in the wild
According to the park's website, a third of the world's population of the critically endangered mountain gorillas live in the region.
Virunga National Park is an UNESCO World Heritage site and claims to be the continent's most biologically diverse protected area.
The park says it is in an area that has been affected by war for more than 20 years.
