I see nutria a lot. There's one who lives in the falling down shed in my side-neighbor's back yard. It ho-hums around even when the dog is barking at it through the fence, but when I walk close he scampers off. There's a section of Sager Creek in my town where I can always see one hanging out. They are supposed to be nocturnal, but I see them often in the daytime.

They are also a pest, destroying wetland (although I don't know exactly how). They look like a cross between a beaver and a possum.
