The Pacific Gophersnake mimics the Rattlesnake is many regards.  The triangular head and colors make it hard to distinguish.  The only difference is the lack of the rattle on the end of the snack.  They are common in very rocky areas.  These photographs were taken in Sunol Regional Park.

    The San Francisco Alligator Lizard can typically be found in rocky areas or anywhere that provides shelter.  They move rather quickly unless in cold weather.  These photographs were taken on the UC Santa Cruz campus.
