Monterey, California, USA. Subtidal, Photographer: Steve Lonhart

Typical doris shape with an ovate mantle with a broad overlap or 'skirt' which hides the body and foot. The mantle is translucent white with a single row of large, rounded, milky yellow mantle glands running around the mantle skirt some distance from the edge. It is usualy described without a yellow border to the mantle but the specimen illustrated here, and another in Behrens (1991) have  adistinct yellow border. The rhinophores clubs are black and the gills are translucent white.

It is reported to feed on the sponge Aplysilla glacialis (Dybowski, 1880) (see McDonald and Nybakken, 1978).

Concerning message #17032:

Hi Bill,
I don't remember ever seeing one in situ without the yellow border (I saw pictures). I have only a bad picture (the rHinophores aren't visible) of one maybe feeding, but it is not on Aplysilla. Theye were several other Cadlina flavomaculata a few yards around this one.

Locality: Anchor Farm, Shale beds, Monterey, 80', California, USA, Pacific, 01 May 2004, Shale bed, silty. Length: 2cm. Photographer: Marcos Perreau Guimaraes.

Cheers,

Thanks Marcos,
I guess this is why it is such a slow process building up good feeding information on these species. Some species make it very easy, always being found near or on their food sponge, but for most it is much more difficult, either because the sponges are very cryptic or the nudibranchs apparently move a lot between meals.
Best wishes,

More on Cadlina flavomaculata

Hi Bill,
Sorting my pics on slugs I saw Steve Lonhart post on Cadlina flavomaculata and your consequent fact sheet. This nudibranch is common to abundant in some diving sites in the Monterey/Carmel/Big Sur area. Late winter to summer I have seen them in great numbers, one every few yards, at a shale bed site called Anchor Farm very near Monterey harbor (about half a mile from the breakwater). But I have seen them in various sites from Schmieder bank (4nm offshore of Pt Sur) to Moss Landing, at depths ranging from 50' to over 200', either on rocky bottom (Fig 1 at Point Lobos and Fig 2 at outer pinnacles) or silty shale bed bottom (Fig 3 at Anchor Farm).

Locality: Monterey/Carmel/Big Sur, 50ft - 200ft+, California, Pacific, Often, rocky, silty. Length: 1cm - 5cm. Photographer: Marcos Perreau Guimaraes.

Dear Marcos,
Thanks for the additional information. From your observations, is the yellow border to the mantle a common feature? None of the written descriptions I have seem mentions it, but it is present in most photos I have seen. You wouldn't by chance have a photo of this species feeding would you?  It is reported to feed on a species of Aplysilla.

Best wishes,
Bill Rudman

The names Cadlina flavomaculata and C. limbaughi did not show up in a search of the website. What have they been changed to?

Dear Steve,
I am afraid that not every species is on the Forum, so an absence just means that I haven't a photo, or haven't had the time to add the missing species. In this case I don't have photos of either of those species of Cadlina. If you have photos you care to share I will be glad to include them on the Forum.

I am pretty sure your animal is Cadlina flavomaculata. With your photo I have prepared a Fact Sheet for the species. Your photo has all the characteristics of Cadlina flavomaculata but it has a yellow border to the mantle which is not mentioned or illustrated in most descriptions of that species. Dave Behrens (1991) has a photo of an animal with a yellow border, so I assume this is variable in the species.
Best wishes,
Bill Rudman
