Tylodina corticalis from New South Wales

April 4, 2001
From: Erik Schloegl


Dear Bill,
Here are two photos of Tylodina corticalis. In both you can see the animal's gills quite nicely.
The UPPER photo was taken at "The Gap", just south of the entrance to Sydney Harbour, New South Wales, on 14 March, 1998. The depth was 20m, the water temperature 20 C.
The LOWER photo was taken at the northern end of Montague Island, southern New South Wales, on 24 January, 2000. The depth was 25m, the water temperature not recorded.

Best wishes,
Erik

Thanks Erik,
These photos show their external characteristics very well. The order name Notaspidea means 'back shield' which is a reference to the large external shell on it back. And the common name Side-Gilled Slug is a reference to the position of the gill on the right side of the body (see arrow I have added to Erik's lower photo).
Best wishes,
Bill Rudman
