Limapontia depressa from Orkney Islands, UK

November 5, 2009
From: Ian F. Smith

Dear Bill
You may like to use the attached picture of Limapontia depressa from the Ouse, Finstown, Orkney islands, U.K. The Ouse can be seen in my habitat photo.

In the picture it is nearing high tide, so the mud with filamentous algae is covered. The sea comes in under the road causeway on the left. Salinity is reduced by a burn [small stream] flowing in.

Locality: The Ouse, Finstown, intertidal, Orkney, Scotland, North Atlantic, 24 April 1975, Intertidal mud in brackish enclosed arm of a bay . Length: 4 mm. Habitat photo at http://www.geograph.org.uk/photo/235398 Photographer: Ian F. Smith.

Best wishes

Dear Ian,

Thanks for this. We didn't have a photo of Limapontia depressa so this is a welcome addition. I must say I sometimes wonder if it is possible to distinguish this species from L. capitata just from photos. The difference in head morphology is not that easy to see and unless we have very high magnification the difference in placing of the anus and renal openings [close together in L. capitata and far apart in L. depressa] can't be seen.

Best wishes,
Bill Rudman
