Now, I'm just brainstorming here with "alternate evolution" ideas, a big ol' "what if" thing.
Could the chupacabra actually be a terrestrial / semiterrestrial bat species? A critter like the giant vampire bat from the pleistocene that, once on
an island, simply lost its need to fly? The wings returned to being walking / gripping limbs, it maintained its hemovorous diet, but remained totally
nocturnal.

Who knows
