Tambja verconis on what appears to be a bryozoan.
Tambja verconis (Basedow & Hedley, 1905)
Yes, I know Tambja verconis has been done before as BOW 656 back in 2009, but how could we not revisit Tambja verconis given the great pictures my dive buddy Jim Black took on a joint trip to South Australia recently. T. verconis was probably the second most common nudibranch Jim and I saw on the trip in March. Although it was quite plentiful on the jetties in the Melbourne area, the same cannot be said for the Adelaide area where we did not see a single specimen. To quote Bill Rudman on the distribution of T. verconis
"... this species is found around southern Australia and northern New Zealand. On the east coast of Australia it has been found as far north as Port Stephens, but as it is dependent on Bugula for its food, its is never a permanent resident anywhere, its presence being controlled by the irregular appearance and disappearance of its food..."
T. verconis was named after Sir Joseph Verco (Bill Rudman's Sea Slug Forum).

Diving since 1970...with over 7000 dives logged. Shoots Nikon D-300 in Subal Housing with Ikelite strobes. Macro Mate on 105mm for supermacro.
Jim's photography has been featured in a number of books and publications including Helmut Debelius' Nudibranchs and Sea Snails of Gosliner, Behrens and Williams Coral Reef Animals of the Indo-Pacific. A photo of Jim petting a shark in "Sleeping Shark Caves" off Isla Mujeres Island, Mexico, taken by Amy Foster his significant other, recently appeared in Dave Behrens' Diving Guide to Cozumel, Cancun & The Riviera Maja.
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!
