An image of two mice fighting over crumbs on the London Underground has been crowned the winner of a prestigious wildlife photography award.
Station Squabble, taken by Sam Rowley, was voted the best image from a 25-picture shortlist selected from 48,000 images submitted to the Wildlife Photographer of the Year: Lumix People's Choice award.
The photographer spent five nights lying on a "tube" platform to capture the low-angle shot.
"I hope it shows people the unexpected drama found in the most familiar of urban environments," Rowley said.
The 25 images shortlisted for the prize, which is voted for by the public, will be displayed at the Natural History Museum in South Kensington until May 31.

The Surrogate Mother, by Martin Buzora, shows a ranger in a park in Kenya looking after an orphaned black rhino. The infant rhinos are cared for at the sanctuary either because of poachers or because their mothers are blind and cannot look after them in the wild.

Losing The Fight, by Aaron Gekoski, captures an orangutan dressed in boxing attire at Safari World in Bangkok.
The shows in the Thai capital were temporarily stopped in 2004 due to international pressure, but they continue with hundreds of people paying to watch the creatures box, dance, and play the drums, the Natural History Museum said.

"Sam's image provides a fascinating glimpse into how wildlife functions in a human-dominated environment. The mice's behavior is sculpted by our daily routine, the transport we use and the food we discard," Museum director Sir Michael Dixon said of the winning picture.
The internet had a lot of thoughts.
"This image reminds us that, while we may wander past it every day, humans are inherently intertwined with the nature that is on our doorstep."
