It's not just us humans that are addicted to mobile phones.

Some of our closest living relatives are as obsessed with modern technology as we are, as this gorilla showed when it became engrossed in an iPhone.

The clip, which emerged on YouTube, features a man sitting on the other side of the safety glass from a gorilla named Jelani at Louisville Zoo in Kentucky.

The man presented his phone to the the video maker so that he could see that he was showing the gorilla pictures of apes

The man holds his phone up against the window and scrolls through photographs while the enormous ape watches attentively.

Humorously it bends its head slightly to focus on the phone and then once it has seen the image it looks away and waits for the next picture.

At that moment the video maker asks the man what he is showing the gorilla and he presents his phone, which shows a human posing with an ape, to the camera.

The man then returns to showing the gorilla, who returns to staring at the phone in interest.

The attentive gorilla stared at the phone and even gestured for the man to scroll to the next picture

Later the gorilla leaned up against the glass and rather adorably appeared to read over the man's shoulder

He continues to show the ape a few more images and on every occasion it stares down at the screen of the phone, despite a number of other distracting things happening in front of it.

Later the man leans up against the wall alongside the glass and rather adorably the gorilla does the same from the other side.

The ape almost reads over his shoulder as the man scrolls through even more pictures, occasionally tilting the phone so the gorilla can have a better look.

The video maker later said: 'I stumbled upon the boy sharing pictures with Jelani touring the zoo with my one-year-old daughter.

'The boy was scrolling through gorilla pictures, and Jelani would motion with his hand to move to the next photo. Both seemed to really enjoy sharing the experience.'
