(CNN) — A park ranger in the Democratic Republic of Congo snapped a picture and posted it to his Instagram page.
The gorillas were apparently copying human behavior with one leaning in to get in the picture and the other standing proudly.
The ranger knows the gorillas well; he helped rescue them as babies.
The park is home to 22 primate species, including three great apes.
It’s estimated that 1,000 mountain gorillas live at the site.
