Gopher Snake
Pituophis catenifer affinis - Sonoran Gopher Snake

Gopher snakes in the wild often take a defensive stance when threatened; they hiss, rear up, and sometimes even strike at the threat in order to protect themselves from harm. In this video, a newly-hatched juvenile Sonoran Gopher Snake trying to cross a road at night is threatened by the bright light and the video camera stuck in its face so it hisses loudly and strikes at the camera before crawling away.
