Pretty Girls, Ugly Faces is a photo fad in which girls take pictures of themselves while posing in an unflattering manner, making a silly face or performing a physically strenuous activity.

Vitaly Gorshkov, a wildlife photographer, captured these animals in their natural habitat. He says that these animals are so hairy that it is difficult to distinguish the front from the back. The oxen aren’t really afraid of humans that is why it is easy to approach them and take pictures.
