Notodoris citrina? from the Marshall Ids
February 7, 2000
From: Scott Johnson
Hi Bill
Here is what appears to be a tiny (around 15mm) specimen of Notodoris citrina. The photo does not show it as it was found. It was on sandy rubble at the base of a vertical wall in fairly deep water on the seaward reef here at Kwajalein. The wall was encrusted with numerous colonies of this yellow calcareous sponge, and I moved it onto one of those colonies for the picture. I assumed that perhaps my bubbles had dislodged it, causing it to fall to the rubble below. So far, this is the first and only Notodoris we've found in the Marshalls, although I've seen the three other species - Notodoris minor, Notodoris gardineri, and N. serenae - at Pohnpei, about 500 miles to the west in the eastern Carolines.

Johnson, S., 2000 (Feb 7) Notodoris citrina? from the Marshall Ids. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/1869Thanks Scott,
I've included an enlarged view of your photo to show how the pattern on the skin matches the spicular skeleton of the sponge both in size and arrangement. Being on the sponge, your photo shows this even more clearly than my photo did.
