“It’s very unusual to see a bear and a wolf getting on like this” says Finnish photographer Lassi Rautiainen, 56, who took these surprising photos. The female grey wolf and male brown were spotted every night for ten days straight, spending several hours together between 8pm and 4am. They would even share food with each other.

“No-one can know exactly why or how the young wolf and bear became friends,” Lassi told the Daily Mail. “I think that perhaps they were both alone and they were young and a bit unsure of how to survive alone…It is nice to share rare events in the wild that you would never expect to see.”
