An infrared camera recently captured photos of a "smiling" wild Tibetan fox in northwest China's Qinghai Province, Chinanews.com reported Monday.

The trail of a square-faced wild Tibetan sand fox was recorded in a biodiversity monitoring program by Shanshui Conservation Center, an indigenous biodiversity protection group in western China's Qinghai province.

Tibetan fox, a least-concern species restricted to the Tibetan Plateau, is known for its smiling face. Some of these photos look very much like selfies by the fox.
