Two gorillas have been snapped apparently mimicking human behavior, in a remarkable selfie with a park ranger who helped rescue them as babies. The photo, taken by a worker at Virunga National Park in the Democratic Republic of Congo, swiftly went viral after being shared on Facebook. 

“Another day at the office...” Mathieu Shamavu wrote alongside the image, which has been shared more than 20,000 times. Female gorillas Ndakazi and Ndeze appear to be naturals in front of the camera; one stands proudly in a power pose with her feet wide apart, while the other leans forward to make it into the shot.

More than 600 rangers work to safeguard wildlife at Virunga National Park, a 3,000-square-mile site. About 1,000 mountain gorillas live here. The gorillas think of the rangers as their parents.
