AN ORANGUTAN has sent the internet wild after trying on a pair of sunglasses when they were dropped into its enclosure.
The fascinating moment was captured on film by a visitor at the Taman Safari in Bogor, Indonesia, and the footage was shared all over social media.
After picking the glasses up, the giant ape appears to immediately understand how to wear them, and adorably rests the temples over its ears, as a little one looks on beside it.
The orangutan even seems to strike a pose or two... if only someone had a mirror.
The video has shared thousands of times and has been viewed by tens of millions of people since it emerged online this week.
Olita Tetsu, who accidentally dropped the glasses, says she was amazed by what she saw unfold.
"I was leaning over to look at some orangutans on the bottom of the enclosure when my sunglasses fell off my head," she told Newsflare.
"After a couple of minutes one of the mama orangutans came over and picked up the glasses and the rest is on camera!"

Orangutans are native to Indonesia in south-east Asia and are mainly found on the islands of Borneo and Sumatra.
They're considered to be one of the most intelligent animals on the planet, capable of understanding complex concepts and solving detailed problems.
A 2008 study of two orangutans at the Leipzig Zoo showed that they can use "calculated reciprocity", which involves weighing the costs and benefits of gift exchanges and keeping track of these over time - becoming the first nonhuman species documented to do so.
Like so many of the world's largest and most interesting animals, orangutans are a critically endangered species, and it's thought that only around 120,000 of them are left in the wild.
Deforestation, poaching and the illegal pet trade are seriously threatening numbers all over Indonesia, and some experts predict that by 2025 there may only be around 45,000 left.
