A stingray appeared cheerful, looking like it was smiling at aquarium visitors.

Footage shows the marine animal swimming behind the transparent glass with a curved mouth at Cebu Ocean Park in the Philippines on December 30.

It delighted tourists seated on food court tables and taking pictures and videos.

Behind the smiling stingray was a diver hugging a baby shark as they swam together amid a school of fish.

Visitor Jessamin Guarra said: 'We had gun visiting the ocean park. The caretakers were making sure the animals were well-attended to.'

Stingrays cannot smile like humans, but their underside can sometimes appear to have a friendly, smiling face. This is an illusion caused by the placement of their mouth, and gill slits on the underside of their body while their eyes are on top.
