An amusing video has emerged of a sea lion appearing to be having a bad dream at a zoo in the UK.
The footage, captured at Dudley Zoo on July 31, shows the Patagonian sea lion performing an array of strained facial expressions as it sleeps.
"It just makes you wonder what kind of dream the sea lion is having. Maybe a growl at something? Look closely at the end, is that a little smile? Like it achieved what it set out to do in the dream?" the filmer wrote online.
