Leech

I have more experience with land leeches than I would have ever imagined or cared for! There is an interesting link in my notes and the comment thread in this spotting. http://www.projectnoah.org/spottings/5747498

This should be in the 'Other' category. I wasn't sure where it should be placed either but just found this 'Leeches have straight digestive tubes, like both annelids and arthropods. But all leeches have a clittelum, a structure never found in arthropods. The clitellum is a modified part of the body wall which secretes a cocoon around newly produced offspring. The presence of the clittelum keeps leeches in the annelid phylum, despite their many arthropod characteristics.
