Attached is a picture of a nudibranch my wife and I observed off the south coast of New Britain, Papua New Guinea in Lindenhaven Bay. The animal was observed at approximately 7 meters depth just off shore a mangrove coast. No one on the boat had seen this species and we can't find it in the books available to us and hope you can help.

We saw it during the last week of January, 2004.

Dear John,
This is one of the many strange, cryptic, species of the aeolid genus Phyllodesmium which are found in the Indo-West Pacific. This one is on the Forum as Phyllodesmium sp. 2.
Best wishes
