A shot capturing the elusive snow leopard on a snowy night has won this year's Wildlife Photographer of the Year award.
The image, taken with a remote controlled camera high in the Indian Himalayas, scooped the top prize for American photographer Steve Winter.
And British teenager Catriona Parfitt won the Young Wildlife Photographer of the Year prize for her dramatic picture of a lion attempting to attack a giraffe in front of an audience of gemsbok antelope.
The winning images were chosen from a record 32,351 entries from 82 countries, and go on show at the Natural History Museum, London.
Mr Winter, a photographer for National Geographic, endured arduous, freezing conditions to set up his series of remote-controlled cameras to capture shots of the extremely rare snow leopard.
Months of waiting rewarded him with a series of photographs of snow leopards - including the winning shot of the animal among falling snow.
"When I finally saw this shot I was very happy," he said. "I was overjoyed every time we got an image. We got a handful of images and each one was a gift."
He said he was honoured to win the Wildlife Photographer award and added: "It's a way to bring awareness to the situation of the snow leopard which is critically endangered."
Catriona took her winning shot on a family holiday to Namibia, which gave her opportunities to watch and photograph some of the African country's wildlife.
The 15-year-old from near Southampton said winning the award was "amazing" and added: "I'd really like a career in in wildlife photography".
