Okenia sp (undescribed)|
2004 and 2007 were big years for the description of new species of Okenia. Ten new species were named, between Terry Gosliner and Bill Rudman. When Indo-Pacific Nudibranchs was published in 2008 we were only aware of three additional undescribed species. Now the "new' Nudibranchs and Sea Slugs Identification contains 12 more undescribed species. This species is listed as Okenia sp. 12 in this new reference.
This beautiful little critter is bright orange with purple at the tips of the rhinophores and dorsal appendages. The appendages are longest along the outer edge and there are two mid-dorsally between the rhinophores and gill. The gill is opaque white. You cannot confuse this species with any other.
One of the larger Okenia's, reaching 20 mm in length; its current geographic distribution includes Papua New Guinea and Indonesia. We will certainly be trying to add the Philippines to this during our March Nudibranch Workshops in Anilao, Philippines, March 2016.
The Indo-Pacific book is now available at New World Publications for $60 + shipping!

Webmaster's Notes: John Greenamyer probably doesn't need an introduction to most sluggers. John has been contributing videos to the site for some time! In fact, the Thecacera video above will be John's 65th presentation on the Slug Site! Pretty incredible when you think about it, to give up taking video of big guys to video our little friends which I believe is up to the challenge of taking video of the larger animals if you are fortunate to find any nowadays! John has been an inspiration along with Alan Grant for prompting my own entry into the world of High Definition Video back in 2006. I am very thankful for the guidance given by both and have never looked back! As the ol' saying goes, it just gets better and better (especially when you are looking at John's videos!).
