The chupacabra or chupacabras (Spanish pronunciation: [tʃupaˈkaβɾas], literally 'goat-sucker'; from Spanish: chupar, 'to suck', and cabras, 'goats') is a legendary creature in the folklore of parts of the Americas, with its first purported sightings reported in Puerto Rico in 1995.
The name Chupacabra comes from the animal's reported vampirism—the chupacabra is said to attack and drink the blood of livestock, including goats.
Physical descriptions of the creature vary, with some describing it as more dog-like (particularly in Southwestern United States) while most others describe it as reptilian and alien-like (in Puerto Rico and Latin America). Some report it as being a heavy creature the size of a small bear, with a row of spines reaching from the neck to the base of the tail.
