This orangutan really has the bit between its teeth – and is determined to get it out.
Chinta, a 25-year-old Bornean orangutan, appears to be giving her teeth a good flossing as she perches on a wooden platform with a stick.
After running the thorned branch through her mouth, she then examines it closely to see what she has picked out.
Chinta was photographed by Miriam Haas at Paignton Zoo in Devon.
Miriam, 56, said: “It certainly looks a lot like Chinta is flossing.
“However, she could also be stripping the bark off the branch.
“I’m a regular visitor to Paignton Zoo. I go at least twice a month.”
Philip Knowling, spokesperson for Paignton Zoo, said: “Bornean orangutan Chinta is 25.
“She has a daughter Natalia who was born on December 22, 2013 and the others in her group include Mali, 21, her daughter Tatau, four, adult female Gambira, 19, and male Wousan, 10.
“Orangutans are threatened by hunting, the pet trade and habitat destruction.
“The Bornean orangutan is classed as endangered by the IUCN Red List, the world’s most comprehensive inventory of the global conservation status of plant and animals species.
“A species is endangered when the best available evidence indicates that it is facing a very high risk of extinction in the wold.
“A major problem is the destruction of rainforest to grow commercial crops such as palm oil.”
