Physical descriptions of the creature vary. It is purportedly a heavy creature, the size of a small bear, with a row of spines reaching from the neck to the base of the tail.
Eyewitness sightings have been claimed as early as 1995 in Puerto Rico, and have since been reported as far north as Maine, and as far south as Chile, and even being spotted outside the Americas in countries like Russia and The Philippines, but many of the reports have been disregarded as uncorroborated or lacking evidence. Sightings in northern Mexico and the southern United States have been verified as canids afflicted by mange. Biologists and wildlife management officials view the chupacabra as acontemporary legend.
The first reported Chupacabra attack was in March 1995 in Puerto Rico when a farmer found eight of his sheep dead and completely drained of blood. He found puncture marks on the chest of each victim. 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. 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 stench 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. An even less common eyewitness account has described it to be a heavy creature, the size of a bear.
Two reports during 2010 stated to have found, and killed, chupacabras, one in Kentucky and one in Texas.
On the news, reporters claimed that El Chupacabra was simply an unknown animal.A sort of "coyote-dog" hybrid. In 2000, a Nicaraguan rancher named Jorge Talavera shot and killed a chupacabra.
The half- eaten skeleton was examined, of course, but the scientists may have switched the bones around to prevent panic, because the skeleton that the scientists handed in had a completely different jaw structure, more teeth and it was complete, while Talavera kept it's front leg.
In 2004, a rancher called Devin McAnally noticed a strange animal eating mulberries under a tree in his yard.
Suspecting that this was the very same animal that sucked 15 sheep just the night before, Devin shot the animal. The beast was given the title "Elmendorf Beast", and was identified to be some sort of coyote- dog mutilation.
