Nemertean worm egg masses

Please note any species that has a question mark after its name (?) is either 'likely' to be that species, or cannot be determined exactly, because of a recent or current DNA revision. Photography is a good tool for identifying some species but many other species need either dissection or DNA analysis to determine to species level.
