2010 may go down as the year in which we finally solve the mystery of the chupacabra. Could this truly be the fabled "goat sucker?" First spotted in the 1990s and allegedly native to Mexico and Latin America, the chupacabra is said to feed by sucking the blood out of livestock. A few others have been shot and examined, including some in Texas earlier this year. Upon examination, biologists think the chupacabra may be a coyote or coyote-dog cross with severe mange.
