I was skinning some beavers today and noticed some small whiteish <sp> bug / worm looking things. I noticed the first one because I was skinning on a black surface. I noticed a few more after that so I started brushing the fur around by the back legs and tail and a couple would pop up and then burrow right back down into the under coat. They were tiny not quite as big as this - dash mark I just put in there, but real close. But the shape was the same as this - the dash mark. They wiggled like a worm. White to kind of clear in color. Not bright white, but against the black background they stood out. Beaver has been dead 3 days and kept cold but never froze. The other 3 had been dead about 2 weeks and frozen solid. No evidence of bugs on them. The beaver with the bugs and one of the frozen ones with no bugs came from the same hut? Any ideas what type of bug it is? Sorry I forgot take a picture. Wanted to clean up quick after that one so I might keep them from spreading to my dogs or clothes and into the house. Since I didn't know what they were, I didn't want to chance it. Hopefully I got 'em all cleaned up. but if they hit the floor I'd never see them and then they'd cling to the dogs or me and into the house. Going to let the new ones freeze for a while and see if that gets rid of them.
