Concerning message #3277:

Dear Bill
I send you photos of Armina sp. 1 eating a sea pen. I was amazed how fast it was eating - in perhaps one minute half of the sea pen was striped and no polyps were left. When the nudibranch crawled away only the hard stem of that sea pen was left.

I found this nudibranch in an area where there are a lot of colonial sea pens and since visibilty is always a bit low, they are out also during the day.

Locality: Maumere, 15m, Flores, Indonesia, Pacific, August 07, muddy with very fine sand mixed with volcanic ash. Length: 5-6cm. Photographer: Teresa (Zubi) Zuberbühler.

Dear Zubi,

Thanks for the photos. I am not sure if this is Armina sp. 1, but at present we don't know enough about these species to make decisions about colour variability etc. Whatever its name is, like all members of the genus, it certainly enjoys eating sea pens.

Best wishes,
Bill Rudman

Hi,

If it can help for geographical identification, I found this couple of Armina sp. 1 during a night dive in Kalabahi Bay - Pulau Alor - East Indonesia. It was in November 1999.

Sincerely,
Bertrand

Dear Bertrand,
Thanks for the photo. Apart from being a useful record of the species it is an interesting head shot of the animal giving us a good view of the colour and anatomy of the head.

Armina sp. 1. from Philippines

From: Erwin Koehler

Dear Bill,
I found two species of Armina, one with black foot and red-orange border (see photos here), the other with a pale blue foot and yellow border. There were lots of both species at this place, nightdive (my dive no.1000), Philippines, Negros Is., El Dorado housereef, March 1999, 8 - 14m
depth.

Dear Erwin,
Thanks for the pics of this species and the other similarly coloured species which I have labelled Armina sp. 2. The arminids are an interesting group which still need a lot of work. There seem to be 10 - 15 species with black and white longitudinal lines down the body. They have other slight colour differences and major radular differences. We don't know yet whether each 'species' has a restricted distribution or whether all species have a wide Indo-West Pacific distribution. Perhaps each species feeds on a different food?

Best wishes,
Bill Rudman.
