You beat me to the punch——I was about to contribute that the chupacabras only exists where the majority of the population speaks Spanish.
It was actually “discovered” in Puerto Rico about 20-25 years ago and the tale spread all over the Spanish-speaking world.
Most of the US “chupacabras” roadkill have turned out to be coyotes. Mangy, maybe, but still coyotes.
Make no mistake about it Chupabara’s are real. Just last week I seen one drinking a Tecate at Don Carlo’s restaurant, his hair was perfect!
