Flabellina bicolor from Bare Island, Sydney

November 23, 2006
From: Nicholas Missenden

Hello again Bill,

Hope you had a great holiday.. Anyway, I was diving yesterday on the South of Bare Island, Laperouse and came across this nudibranch.

Locality: Bare Island, South Wall, 15 m, NSW, Australia, Botany Bay, 20 November 2006, Broken reef, sandy bottom. Length: 2 cm. Photographer: Nicholas Missenden.

 I thought that it was some form of Flabellina but I can't seem to find it in any of my reference books or on your forum. Could you help me identify it please?

Regards
Nick

Dear Nick,
It is indeed a Flabellina - Flabellina bicolor. This is a rare tropical visitor to Sydney. It is apparently feasting on the colony of small hydroids it is crawling on - each of the white blobs is a small hydroid polyp.

Best wishes,
Bill Rudman
