Urban Legend: Photograph shows a chupacabra’s head on a fence.

Status: False.
The rather gruesome photograph displayed above has been circulating on the Internet (without explanation of its origins) since 2003, leading many to speculate about just what it depicts. Guesses include the head of a chupacabra (the mythological “goat sucker”), a dessicated canine head, and a Halloween mask.
This image is actually a work produced by video artist Charlie White and entitled Highland Park, one of a series of nine photographs which comprise his “In a Matter of Days” exhibit. The theme of the series was capturing images of monsters (created by Jordu Schell, a designer of film and television characters) in a variety of “accidental” encounters around Los Angeles.
