Can you help me with an ID. I photographed this ?Polycera under St Leonards Pier in about 3 m.
Have never seen this one here before.
Locality: St Leonards Pier, 3 m, Victoria, Port Phillip, 14 October 2007, Sandy silty. Length: 5 mm. Photographer: Andrew Newton.

This is not a polycerid, but a goniodorid called Goniodoris meracula. It's usually found near, or on, the ascidian it is eating. Often it lives in the hole it excavates in the ascidian's tissue, so it certainly looks a bit awkward crawling over this branching red sea weed. Have a look at the Fact Sheet and the other messages attached to it for more background information on this species
