Nembrotha guttata Yonow, 1993

As a Webmaster, I am always on the lookout for images of slugs that are not only first rate in photography, but also add to the body of knowledge we have are building on our sea slug friends. Jim Black's fills the bill on both counts. It seems that in the past week, a flurry of Nembrotha images have filled the my mailbox. I am going to start addressing these images, one by one starting out with Jim's Nembrotha guttata which incidentally came in already identified! Consulting with Bill Rudman's Sea Slug Forum , I am in total agreement with Jim's identification (for whatever that's worth!) But why is it no where to be found in the Indo-Pacific Nudibranchs and Sea Slugs ? N. guttata evidently enjoys a wide distribution in the Indo-Pacific. One of the first sightings of N. guttata in the Philippines was by Erwin Kohler in the Cebu area. Jim's image adds to the number of encounters in the northern Sulawesi region of Indonesia! I certainly would like to get some high definition video of it! Hey, what's wrong with dreaming! I never thought Kalinga ornata would be part of my life time experience either!

WEBMASTER'S NOTES: The authors of Indo-Pacific Nudibranchs and Sea Slugs heave responded (07/13/10! The long and short of the discussion has what I have called Nembrotha guttata as Nembrotha sp. 3 in their book! A second exmination of the information at hand has convinced me of the error of my ways! The image to the left was taken on a recent Philippines trip and is almost certainly Jim's animal!

Jim has been a solid supporter of the Slug Site since day one. His countless contributions put him near the top of the list of photographers who have greatly expanded our knowledge of sea slugs. There are a lot of kids in the formative stage of their education who are getting their first introduction to our sea slug friends via the great photographs Jim and other contributors have made to the site. My hat is off to Jim for making this presentation possible!
