A pair of mischievous gorillas were caught sharing a sexual embrace by an unexpected photographer.
Shirley Kroos, 30, was visiting Rotterdam Zoo in the Netherlands when she caught a pair of young gorillas up to no good.
The male gorillas who were caught in the act are Aybo, three-and-a-half, and Thabo, three, and are residents at the zoo.
The shocked gorillas, who appear to know they’ve been caught, can be seen embracing in multiple ways much to the photographer’s shock.
However, despite their awkward eye contact, the gorillas don’t seem to mind their audience, as a selection of photographs show their continued endeavours.
Shirley said: “They were doing some adult things with each other playfully.
“Before and after they were running around with some toys they were given by the zookeepers.
“So they were just in a playful mood and enjoyed each other’s company.
“It was great watching these two boys having fun together – they made me laugh and it was very unique capturing them on camera.”
