This is the hilarious moment a troop of gorillas run for cover when it starts to rain over their enclosure.

The Western lowland gorillas at Oklahoma City Zoo in Oklahoma, USA, show they really are our closest ancestors by making a beeline for shelter when the heavens open.

Senior animal caretaker Stephanie Smith witnessed the primates bound one-behind-the-other when it started to rain and whipped her phone out to record last Wednesday (18.08).

Stephanie, 30, said: "Previously, I have seen the animals make funny facial expressions when it rains so I knew there was a chance they might do it again.

"The best part about working with gorillas is getting to know all of their individual personalities and seeing how they interact with each other as a family troop.

"Gorillas are naturally very stoic so it is really special to witness them being playful or silly.

"Working with animals, especially primates, means that every day is different and I am always amazed by their intelligence and their reactions to different situations.

"Togo is an amazing silverback and leader of his troop.

"We have three juvenile gorillas ranging from three to six years old so a lot of their day is spent playing and Togo and the adult females will often join in."
