Trapania sp. 7 undescribed

This is Trapania sp. 7 in Indo-Pacific Nudibranchs and sea Slugs. It was inadvertently reported as known only from the Great Barrier Reef in Australia. The photo in the book, however, was actually taken by Christiane Waldrich, in Sumbawa, Indonesia. We have since found it there again. The species is quite characteristic, and Gerd's sighting adds nicely to the species geographic range. The rhinophore and gill color along with the body stripping separate it from all other Trapania. Keep up the good work guys.

After my wife learned diving in 1965 (diver license no. 761 of Germany) and since 1992 we have been diving together after stopping our other hobbys sailing and winter sports.

In the last 20 years we traveled to South East Asia: Manado, Tioman, Phuket, Sipadan, with live board to Andaman sea and the last 10 years to the Philippines (Moaboal, Negros Dumageti and Sabang Beach.

We have specialized in the macro world, special nudibranchs and all other critters

In the meantime we came in contact with Helmut Debelius. He lives only 6 kilometers away from our home. I was able to attend the birth of the book Nudibranchs of the world of Helmut and Rudi Kuiter at Helmut's house.

Helmut published for the book Seahorses and their relatives of Rudi a DVD. I was one of the four underwater videographer for this DVD, sequencies with the pigmy seahorses Severnsi and Pontohi were taken at Bunaken, Manado.

This Year I bought a new underwater video equipment:

Camera: Canon XA10 with HD
Housing: Blue fin from light&motion
Light: SOLA 2000

My wife Helga is specialist for finding small things, mostly with the magnifying glass. She found this nudibranch at our favorite dive site "The Hill" during the afternoon dive, 25th Feb.2012. The nudibranch is only about 6-8 mm large. The color is more intensive blue as the picture shows

This dive site is a sandy area, depth between 13 and 18 meters and a area for critters. We found as well this year some days before Rudi's Dactylopus kuiteri after 2008 and 2006.
