Exploring the Mystery of the Chupacabra Sightings

Mamerto Adan is an engineer by profession, but a writer by night. He loves toys and knives. He also has a martial arts background.


There are stuffs out there that can’t be explained. No matter how advanced our way of thinking is, or how deep we could do our studies, our capabilities as humans are limited. Science, our best tools to explore our world, not to mention the whole universe is equally limited, and so far, we only scratched the very surface on what we could learn. That’s why scientist never really abandoned the notion of alien life somewhere in the universe. The odds are simply there, that in the vast universe with countless stars, with possible star systems in them, there might be life out there.

But the problem here is that the claims about alien life by Average Joes are simply too outrageous.

Most people often get too excited with meeting outside visitors, so much so that they ended up fabricating stories of close encounters. This ruined the educated notion of alien life and turning it into cartoonish guest works. It did contribute to humanity’s pop culture, or even in local folklores as in the case of a creature somewhere in South America. The said creature has reptilian body, though descriptions might vary. Remember the legendary Chupacabra? I must admit that it is fun to say, but the problem here is that it’s too shady to believe.

General Description

Again, the general description of the creature may vary, but the most common is the reptilian type. It’s a scaly beast, green in color and sports spikes, or quills on its back. This will bring in mind a prehistoric creature coming out from the Triassic. It’s size however is not that monumental, as it is said to be 5.5 feet tall. It never ran on all four but stands like a kangaroo and hops like one. In addition, it got oval head, large glowing eyes, and a foul stench of sulfur.

Other description of the creature gave it a canine feature. People claim that it resembles a breed of strange wild dog, and if that’s the case it lacks shaggy fur, as Chupacabras are said to be hairless. The spinal ridge on its bare back is more pronounce, and the same can be said on eye sockets, claws, and fangs.

And now, for the feeding habit. It’s classy name is Spanish for “goat -sucker,” and as the name suggests, it kill its prey not by biting, but by sucking. It drinks the blood of its unfortunate victim, leaving holes in the shape of triangle on the carcass, much like a vampire.

And as what all reports indicated, all Chupacabra victims are livestock.

Connections With Aliens

From the eyewitness descriptions, it won’t come as surprise that the creature will be connected with anything extraterrestrial. And indeed, some people reckoned that the Chupacabras are some sort of pets by alien visitors that got loose or left behind. Or the creature might be the alien visitors themselves, as they resemble extraterrestrial beings called “Greys” (or Grays). Alien fans out there will fondly remember the Greys, being the stereotypical extraterrestrial species of pop culture and movies. That humanoid creature from outer space, with a bulging oblate head, large blazing eyes, small bodies, and grey skin (hence their names) greatly shaped our mental images of alien beings. And like them, the Chupacabra has large blazing eyes and oblong head, though this is where the resemblance ends, as I never heard of any Greys sporting green skin and raiding our uncle’s farm.

And if that sounds outrageous, there are speculations that the Chupacabras are escapees from NASA experiments.

Resemblance to a Film Creature

As people make claims on the authenticity of the creature, others aren’t willing to buy it. Benjamin Radford is a skeptic and a writer, and he spent five years investigating the Chupacabra legend, and he documented his findings in his book Tracking the Chupacabra. And based on the descriptions made by eyewitnesses, Radford reached a conclusion that the cryptid was nothing more than a film creature.

The first sighting of the Chupacabra was reported by a woman in Puerto Rico, going by the name Madelyn Tolentino. The date was March 1995, and she claimed that she saw the creature in the town of Canovanan, where it killed farm animals and pets.

As it turns out, Tolentino had seen the movie Species before making the report. And her description of the creature bears a resemblance to Sil, the film’s lead monster. This theatrical alien has all the Chupacabra features, from the reptilian skin, the head shape, eyes, and even the spines on her back. It might be possible that the eyewitness thought that the events in the Species movie was really happening in real life, hence the birth of the Chupacabra legend according to Radford.

But how about the dead animals it left? One cannot rule out the possibility of a more natural occurrence, like animal attacks on livestock.

The Mangy Mammalian Predator

Though people claimed that the carcasses left by the Chupacabra attacks were drained of blood, the necropsy has different says. In fact, it was never confirmed by necropsy that the animals were left bloodless. And the holes left on the animal victims are consistent with the canines of real-life predators that always come in conflict with ranchers and farmers.

Coyotes and other mammalian carnivores.

Anyone familiar with how wild animals kill their prey will easily recognize the signature wound on the prey. When they seize their unfortunate victim, they will go for the neck, hence the vampiric bitemark on the carcass. But should these predators consume their prey afterwards and not just left them in the open? But they would if the predators are inexperienced or injured. And the prey could survive for a given time before dying due to shock or internal bleeding.

And lastly, the alternate description of a Chupacabra as a hairless dog-like creature with ridges on its back could be explained by sightings of wild animals infested with Sarcoptes Scabiei, the mite that caused mange. Animals hit by mange will experience loss of fur, their skin thickening and appearing leathery, and ending up smelly. And if you think that a mange infected coyote is just a hairless dog, a wild animal lurking in the dark could appear unusual or unrecognizable and might induce shock to the observer. I mean, just look at photos of a bald black bear on the internet.

And did I mentioned that stray Mexican Hairless Dogs also suffered from misidentifications.
