Photos of Elysia rufescens

August 15, 1999
From: C. Carlson & P.J. Hoff

Here are some scans of Elysia rufescens you can probably use.  Sorry about the glare on the mouth parts on the full animal.
UPPER: 60mm; Guam, Pago Bay, reef flat; 13 July 1984  on Bryopsis pennata
MIDDLE: dorsal view of body behind the head, normally hidden by parapodia showing pericardial bulb and branching blood vessels. The green reticulate pattern, is the finely ramifying ducts of the digestive gland filled with plant tissue, probably chloroplasts.  Guam, Agat, Ga'an Point, reef flat;  3 April 1989 on Bryopsis pennata   
LOWER: Variety showing red spots on interior of parapodia as described by Pease. About 30mm long;  Guam, Pago Bay, reef flat; 1 April 1971 on Caulerpa racemosa.   
The first time we found E. rufescens it was on on the inner side of a narrow reef flat to the left of the Marine Lab at the University here.  There was a lot of Bryopsis pennata toward the reef margin but that was populated by what we are calling E. grandifolia Kelaart, 1859.
You are going to owe me a couple of litres of martinis if I ever make it to Sydney.

Dear Clay & Patty Jo,
Thanks for the great photos. If you ever make it to this end of the Pacific, I am sure I can arrange an appropriate reward.
Best wishes,
Bill Rudman.
