Asiatic lion, “Heidi” stretches on her hind legs for meat in their enclosure during a photocall at London Zoo on August 24, 2017, to promote the zoo's annual weigh-in event. During the weigh-in, animals across the zoo have their vital statistics recorded including their height and weight and the information is then shared with zoos across the world to help zookeepers compare important information on thousands of endangered species.
