Fans of wildlife photography around the world can choose their favourite from 25 images, pre-selected from over 48,000 image entries from 100 countries.
The shortlisted pictures are currently on display at the Natural History Museum's exhibition, until the voting ends on 4 February. The winner will then be showcased until the exhibition closes on 31 May.
Tim Littlewood, executive director of science at the Natural History Museum, and member of the judging panel, said: "The Lumix People’s Choice images capture the essence of the competition.
"They all ignite a reaction about the natural world and make you see it differently. Showcasing breathtaking beauty, compassion and cruelty, it is impossible not to be moved by them."
Photographers of all ages and abilities can enter the 2020 Wildlife Photographer of the Year competition until 11.30pm on 12 December.
Wildlife Photographer of the Year is developed and produced by the Natural History Museum, London. Vote here
