El Chupacabra

The Chupacabra, or β€œgoat sucker,” is a cryptid creature said to stalk and kill livestock.  Between the months of March and August in 1995, more than 150 farm animals were left dead in Puerto Rico.  The unfortunate animals were left drained of blood, with two puncture wounds in their neck.  The situation became dire enough that Mayor Jose Soto recruited volunteers to help hunt the creature responsible, but they ultimately came up empty.  While tales of the Chupacabra may have originated in Puerto Rico, they quickly spread throughout the Americas.

The Chupacabra is most often described as a small, reptilian humanoid with a row of spines that run from its neck to the base of its tail; although some witnesses claim that it looks like a strange breed of hairless wild dog with a pronounced spinal ridge, unusually pronounced eye sockets, fangs, and claws.  Regardless of appearance, the Chupacabra literally sucks the blood of its prey, exsanguinating the unfortunate animals on which it feeds.  

Theories on the creature's nature and origin vary from mangy coyotes to extraterrestrial genetic experiments gone wrong.
