LYING back in the snow, these two polar bears share a cuddle as they call time out on playtime. The brother and sister embrace with a friendly hug, as they catch their breath after a busy afternoon. These adorable photographs were captured by Russian photographer Alexey Tishchenko, 43, after his love of wildlife and nature led him into photography. Pictured in Churchill, Canada, these images capture the cute relationship between these two bears perfectly. 'These young polar bears are brother and sister,' explains Alexey.
