Compare: ...with the monster itself:
A bald racoon has been seen running around the Toronto neighborhood of Parkdale. The home-owners there have taken a few pictures, as well as the video below. "Baldy" (or "The Toronto Terror", according to some) appears healthy and well hydrated, but none of the local scientists have seen a totally bald raccoon before. The youtube clip also shows a couple of normal raccoon companions, so the ID is not really in doubt.
Most writers who IDd the Montauk monster as a dead raccoon assumed that the hairlessness was a matter of taphonomy--the fur was lost after death. Maybe not. Mange/Alopecia seems to make them look pretty weird as well.
