A video has emerged showing the unique moment a gorilla appears to ballet dancing in its enclosure.
Filmed at Twycross Zoo, Leicestershire, UK, tourist Helen Fairhead saw the gorilla pirouetting and refused to miss the opportunity to film it on her phone.
The zoo's director of life sciences Dr Charlotte Macdonald said Lope's "dance" is evidence of him playing - an important aspect of young apes' behaviour.
