We have a small critter that leaves mussel shells, snail shells and acorn shells on the steps of our dock. I saw him this afternoon up close and have no idea what he is.  He was small with a long thin tail. After a quick google, I think it might be a nutria. From what I read that’s not good. Any ideas on what it might be and what to do about it?  If it’s an otter I would welcome it but I’m not sure about the other two.
