For my skeleton preparation I was told I was doing a Winter Least Weasel, and since mine had a black tipped tail, Prof Hinshaw told me it was specifically then an Ermine, which is adorable. Here I included a picture of a least weasel, so you can see what I was dealing with, and how cool and cute they are. My specific specimen was winter, so the coat is a gorgeous white. I will upload a picture once I find a suitable picture.
