Tambja morosa from Indonesia

September 27, 2002
From: Sabine Noack

Dear Bill,
We found these 4 differently colored Tambja morosa at the same dive site (Pulau Pisan, Horseshoe Bay, Rinca , Indonesia).
The date/time was 29 September 2001 around 15:00

• Number 1 was found in ~25m, it was ~5cm long, black with bright blue markings. The color around the gills was bright green. It was crawling on the sandy bottom.
• Number 2 was found in ~20m, it also was ~5cm long, black with blue-green markings (gills, spots and line around the mantle had the same color). It was crawling across a sandy patch on the reef.
• Number 3 was found in ~15m, it was ~4cm long. Its lower sides were dark green, the back was black and the markings were all in the same blue-green color. It was crawling across a hard coral.
• Number 4 was found in ~7m, it was ~5cm long and very very slowly crawling across a big tunicate (Polycarpa aurata). It was black with bright blue dots, a bright green ring at the bottom of the gills. The color on the inside of the gills was green, the outside was blue.

Thanks Sabine,
I have often wondered about the small discrepancies in color you find in this 'species' but have been unable to find any consistent differences.
Best wishes,
Bill Rudman
