It is a cryptid 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 latter's Latin American communities
The name comes from the animal's reported habit of attacking and drinking the blood of livestock, especially goats.
The most common description of Chupacabra is a reptile-like being, appearing to have leathery or scaly greenish-gray skin and sharp spines or quills running down its back.[15] This form stands approximately 3 to 4 feet (1 to 1.2 m) high, and stands and hops in a similar fashion to a kangaroo. In at least one sighting, the creature hopped 20 feet (6 m). This variety is said to have a dog or panther-like nose and face, a forked tongue and large fangs. It is said to hiss and screech when alarmed, as well as leave a sulfuric stench behind. When it screeches, some reports note that the chupacabra's eyes glow an unusual red, that gives the witnesses nausea. Some witnesses have reported seeing bat-like wings.
Another description of Chupacabra, although not as common, is described as a strange breed of wild dog.This form is mostly hairless, has a pronounced spinal ridge, unusually pronounced eye sockets, fangs, and claws. It is claimed that this breed might be an example of a dog-like reptile. Unlike conventional predators, the chupacabra is said to drain all of the animal's blood (and sometimes organs) through a single hole or two holes.
