Originally spelt without the 's', but now days is sometimes spelt with it, the Chupacabras was unheard of before the mid-1990s. The term "Chupacabras" was coined by Puerto Rican comedian and entrepreneur Silverio Pérez in 1995 in refernce to reports of attacks on livestock. The word means "Goatsucker" in Spanish. The Chupacabra became a cryptozoological phenomenon with international fame due largely to extensive internet coverage and interest [Chambers Dictionary of the Unexplained].

The Chupacabra varies widely in appearance and there are many images that claim to depict it. Often any grotesque looking animal or alien image is described as a Chupacabra.
