Discodoris ylva Marcus, 1965 ?

This species is somewhat similar to what we are calling Discodoris coerulescens. This one differs in in its smaller size, more snow white coloration, narrower body, and lack of any kind of a marginal band. It differs a bit from the original description of Discodoris ylva, which was yellowish in color. The first specimen (two photos) was found under dead coral on the seaward reef of Kwajalein Atoll, and it measured 10mm in length.

The next two shots show a specimen found 1 September 2008 that had undergone severe autotomization. It is missing most of its mantle margin and including its right rhinophore. The missing portions enable us to see the reproductive opening and fairly long oral tentacles.
