Cylindrobulla sp. e434

This appears by the shell morphology to be a species of Cylindrobulla or Ascobulla. Our animals appear most similar to one figured in Gosliner et al (2008) as Cylindrobulla sp. 2 from the Indian Ocean. There are still some questions about where the group belongs (see the Sea Slug Forum). This species is known from the Marshalls from several specimens found at Kwajalein. The first four photos below show a specimen found on 5 September 2009 at a depth of about 5m under a rock on a Kwajalein Atoll lagoon reef. When disturbed, they will release a white slimy substance, seen here stuck to the tip of the spire on the left side of the photo.

I suppose those must be the rhinophores.

The specimen below was found on a Kwajalein Atoll seaward reef on 25 December 1998.

It is a bit tough to be sure if all these are the same species.
