Notaeolidia gigas from King George Island, Antarctica

From: Bill Rudman

In a recent message [#19656],  Michael Schroedl mentioned Dirk Schories' website with nudibranch photos from King George Island, Antarctica. Two animals illustrated in Dirks's website are Notaeolidia gigas, and another aeolid which has been misidentified as that species [see message #19680]. Dirk has kindly allowed me to post his photos of both species on the Forum for comparison.

Notaeolidia gigas has a distinct mantle 'skirt' and the cerata, arranged in irregular rows, are confined inside the 'skirt', which is thrown into sinuous folds. There is also a clear space, free of cerata in the middle of the back, and the rhinophores are shorter and wrinkled.

Locality:  Admiralty Bay, King George Island, Antarctica.  06 February 2003. Photos: Dirk Schories. [ http://www.guiamarina.com/antarctica/ ]

This is a very useful set of photos.

Best wishes
Bill Rudman
