Top 10 nature photos of all time
What do a dancing polar bear, a thresher shark and a group of elephants have in common? They're just a few of the breathtaking images that have been selected as the Top 40 Nature Photographs to celebrate the naugural 'Earth Day Green Auction.'
The collection, which represents a wide range of styles and genres that span over 100 years of history, was chosen by members of the International League of Conservation Photographers (ILCP). You can bid on selected prints here.
We've got some of our favorites on display. To see the rest of the photographs, visit the full ILCP gallery.
