This has baffled me and my wife. We are finding these in only our bathroom and at least 1 a day...they are always alone. They are about the length of your pinky finger nail. The little head pops out, and drags the whole "pod". I have opened one and did not find eggs, dung, or anything except space...
The head is about 3-4 segments and after that the body is completely transparent.
We live in the San Diego, CA area...
