Photographer Dmitry Kokh discovered polar bears living in an abandoned weather station in Kolyuchin, in the Chukotka Autonomous Okrug of the Russian Federation, while on a trip to Wrangel Island, a Unesco-recognised nature reserve that serves as a refuge to the animals

I had dreamed about photographing polar bears for a long time. Some time ago my hobby, wildlife photography, ceased to be just a hobby and turned into a large part of my life. And if you devote so much time to an activity then your goals should be ambitious. Most of all I like to take pictures of large marine animals, whether on land or under water. Not everyone knows, but zoologists classify polar bears as marine mammals since they spend most of their time on ice floes away from land. And their paws even have webbing.

There are only a few places on the planet where polar bears can be found in large numbers. One of them is Russia’s Wrangel Island, a nature reserve under Unesco protection that is often called a polar bear maternity ward. The place is very inaccessible, which may be bad for tourists but is great for the animals.
