The most common description of chupacabras is a reptile
-like being, appearing to have leathery or scaly greenish-gray skin and sharp spines or quills running down its back.
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 was reported to hop 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 behind a sulfuric
When it screeches, some reports assert that the chupacabras' eyes glow an unusual red which gives the witnesses nausea.
Another description of chupacabras, although not as common, describes a strange breed of wild dog.
This form is mostly hairless and 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 chupacabras is said to drain all of the animal's blood (and sometimes organs) usually through three holes in the shape of an upside-down triangle or through one or two holes.
