Elephants pose for thermal pictures at Whipsnade Zoo
Elephants at Whipsnade Zoo have been photographed by a thermal camera as part of a project hoping to help the conservation of elephants in the wild.
Thirty-thousand pictures were taken over two years as part of Zoological Society of London's research to develop technology to address human-wildlife conflict.
Human-Elephant Alert Technologies (HEAT) uses thermal cameras to spot elephants using their heat signature.
