Finnish photographer Lassi Rautiainen witnessed a rare friendship between a female grey wolf and male brown bear that spent nights together enjoying dinner. Rautiainen took photos of the pair for ten nights.

According to the 56-year-old photographer, the two spent hours together from 8 p.m. to 4 a.m.

"It's very unusual to see a bear and a wolf getting on like this," Rautiainen said, according to Daily Mail. "No one can know exactly why or how the young wolf and bear became friends. I think that perhaps they were both alone and they were young and a bit unsure of how to survive alone."
