Every year, photographers from around the world submit their best work for consideration for the World Nature Photography Awards. Images ranging across all flora and fauna are considered and the winners are always spectacular.“We’ve been thrilled with the quality of work that was entered into the awards,” Adrian Dinsdale, co-founder of the awards, said in a statement. “It was such a privilege to see the competition’s philosophy come to life – our photographers really are shining a spotlight on the wonders of the natural world in a way that reminds us to do everything we can to protect the future of our planet.”The awards are broken down into separate categories. Here are some of the select winners:Animals in their habitatGold: Thomas Vijayan had to wait several hours to catch this best-in-show shot of a critically endangered orangutan in Tanjung Puting National Park, Borneo. “I had this frame in my mind so… I firstly selected a tree that was in the water so that I [could] get a good reflection of the sky which can make the image look upside down, [and] then I climbed up on the tree and waited for hours,” Vijayan revealed.Silver: Vladimir Cech spotted a red fox walking along a felled tree in the Bohemian Forest of the Czech Republic.Bronze: Arlette Magiera captured this shot of a male kongoni trotting in Murchison Falls National Park, Uganda.Behavior: BirdsGold: Dale Paul, Canada. This Great Horned Owl has just jumped from its perch in the trees to begin flight. She has thrust her wings forward to gain momentum. As the wings connect in front of her it appears as though she has formed a perfect flying saucer. The image was taken near High River, Canada.Silver: Andy Pollard.

Dragonfly and damselfly sex is a very conspicuous event, easily recognized by the heart-shaped “wheel” formation of mating pairs. Dr. Tan was lucky to encounter several pairs during a morning walk at Gardens by the Bay, Singapore. He approached quietly to avoid scaring the pair away; and positioned his equipment carefully to get both damselflies in the same plane.Silver: Melissa Robertson, United StatesBronze: Janus Olajuan Boediman, IndonesiaBehavior: MammalsGold: Patrick Nowotny.

A white Rhino is dehorned to prevent being killed by poachers. It’s a highly effective strategy as well as a conservation measure of last resort. All rhino species are, or have been, on the brink of extinction due to the popularity of their horn in Asia. But to clarify: rhino horn is composed of keratin, the very same substance that forms our fingernails. Nowadays, even in Asia, it’s widely known that rhino horn has no medicinal value or any other beneficial effect. However, the fewer rhinos there are, the higher the price of their horns, which unfortunately has made rhino horn consumption a status symbol.
