A Flatworm that was attached to an old submerged can. Not totally positive of the ID on this one, but seemed to be the best fit according to the Peterson Guide. It has four eye patches, the two obvious ones and two very slightly forward in between the other two that are quite faint (seen better with loupe). It also has eyes along the front margin. About 1.25 cm. Discocelides ellipsoids might also be a possibility (diagram better for D.e in Gosner, but C.m diagram in Pollock seems like good fit, doesn't show D.e).
