Elysia viridis from Scotland
April 8, 2008
From: Jim Anderson
Dear Bill,
I've never had much luck finding this common species until late last year (28 Oct) when we found hundreds in the shallows of the sea loch we were diving. They were abundant on kelp and rocky substrates with many 'flattened' out into the leaf shape they adopt. It was not a particularly sunny day but bright.
Locality: Jenny's Reef, Loch Long, 6 m, Scotland, Atlantic Ocean, 28 October 2007, Sea loch. Length: 25 mm. Photographer: Jim Anderson.

Anderson, J, 2008 (Apr 8) Elysia viridis from Scotland. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/21032Dear Jim,
It's good to get photos of some of these 'common' animals. It's surprising how often they are the worst represented in collections both in terms of specimens and photos. I have added a couple of close-ups to show some features of this species. In the upper photo we can see the vessels which branch out over the parapodia. Some researchers consider the branching pattern differs characteristically in each species.
In the lower photo I have included an inset showing the accumulation of living green algal chloroplasts which are nutured in some species [see Solar-powered sea slugsPage]
Best wishes,
Bill Rudman
