I found this worm-like hitchhiker in my sump. It has been extending and contracting as in the images below. When extended it reveals some sort of appendages -they are hard to make out though as they are quite small. Fully extended it's maybe 1/2" long.
My best guess is peanut worm from images I've found on line. Anyone else have thoughts?
