In my previous article I wrote about the possibility that at least some sightings of “monsters” may have been caused by normal animals exposed to dangerous pollution. I quoted Jon Downes – the Director of the U.K.-based Center for Fortean Zoology – who said of all this in relation to sightings of giant eels: “One theory suggests that these rare, naturally occurring, mutations may now be on the increase due to pollution. PCBs [polychlorinated biphenyls] have long been implicated in causing sterility in fish. Could they be causing the birth of much larger eunuch eels in the deep lakes of Scotland?” The inference being that the Loch Ness Monsters just might be huge, pollution-soaked eels. I’m going to expand on the matter of all this for one good reason: where there is dangerous pollution, there may be strange creatures. Or, people and animals affected by the likes of PCBs. All of this brings me to a specific part of today’s story – something that has a connection to none other than the Chupacabra of Puerto Rico.
