Okenia sp. (undescribed)
The 2016 Slugfest at the Crystal Blue Resort was a smash, producing an amazing list of some 500 species. On that list is a number of newly discovered undescribed species. This new Okenia is one of them.
Members of the dorid nudibranch genus Okenia almost look like aeolids, as they have a series of long projections on the sides of the body, hiding the dorsal gill. The rhinophores are perfoliate. This distinctive species has a yellow body with white lateral and dorsal projections. Okenia's feed on bryozoans.
We don't know much about this species biology but will be looking again for it, to learn more, next May at the Nudibranch Festival back at Crystal Blue.

Three weeks in Anilao this spring at a nudibranch workshop run by Dave Behrens (Mike Miller assisting on half of it) yielded about 300 species for my partner Anthony Holley and me (almost 600 for the group!).
Using a Nikon D7000 with 105mm lens in a Nauticam housing, twin Inon Z240 strobes, and an SMC fixed to the front of the port much of the time we went hunting and every dive turned up more and different nudis - about 80 new to us.
Quite a few of them turned out to be juveniles as identified by Terry Gosliner- interesting how different they can be from their adult versions!
