Polycera capensis from Jervis Bay [2]

June 4, 2003
From: Sue Newson

Hi Bill,
To continue my previous message, about Polycera capensis in Jervis Bay [New South Wales, Australia] the third sighting of this nudibranch was in the same general area west of Murrays Beach Boat Ramp (26 April 2003) at a depth of 12m. I have attached 3 photos of this one showing different aspects.

Further information regarding these dives that you might find of interest was the other species that were sighted.

6 January 2000: Armina sp., Doriopsilla carneola, and Hypselodoris obscura.
30 NOvember 2002: Doriopsilla carneola
26 April 2003: Hypselodoris obscura

Thanks Sue,
You mentioned in your previous message that this could be a juvenile, and from the algal filament in the upper photo I guess it is quite small. The main difference is the absence of the pair of yellow papillae flanking the gills [sometime called extrapallial processes]. There is usually some sign of these even in juveniles. I am sure this is P. capensis so I guess we can say that this animal has a slight inperfection.
Best wishes,
Bill Rudman
