CHUPACABRA

Physical descriptions of the creature vary, some describe it as reptilian and alien-like , generally as a heavy creature the size of a small bear with a row of spines reaching from the neck to the base of the tail. Others depict it as more dog-like.
Sightings have been reported in Puerto Rico since the 1970s, and this creature has since been reported as far north as Maine, as far south as Chile, and even outside the Americas in countries like Russia and Philippines. All of the reports are anecdotal and 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. According to biologists and wildlife management officials, the chupacabra is an urban legend.
