Some of the finalists for this year’s Wildlife Photographer of the Year have been announced by the Natural History Museum in London.

This year’s contest attracted entrants from 92 countries; contestants who are both professional and amateur submitted almost 50,000 images to the 2017 competition.

This year’s winners will be announced on October 17, 2017, at a ceremony held in the Museum’s Hintze Hall. After the ceremony, an exhibition of this year’s photos will run from October 20, through sometime in spring 2018.

This year’s competition has produced some stunning images by some famous wildlife photographers, and includes images of seals, anemonefish, and the tragic image of a seahorse anchoring itself to a plastic cotton bud.

If you want to take part in next year’s competition, it opens for entries on October 23, 2017.
