The Chupacabra (IPA-est?upa?ka??a, from chupar "to suck" and cabra "goat", literally "goat sucker"), is a legendary cryptid (a creature whose existence has been suggested but is regarded as highly unlikely) rumored to inhabit parts of the Americas. It is associated more recently with sightings of an allegedly unknown animal in Puerto Rico (where these sightings were first reported), Mexico, and the United States, especially in the latters Latin American communities. The name comes from the animals reported habit of attacking and drinking the blood of livestock, especially goats. Physical descriptions of the creature vary. Eyewitness sightings have been claimed as early as 1990 in Puerto Rico, and have since been reported as far north as Maine, and as far south as Chile. It is supposedly a heavy creature, the size of a small bear, with a row of spines reaching from the neck to the base of the tail. Biologists and wildlife management officials view the Chupacabra as a contemporary legend (urban legend).
