Part three of three Eubranchus messages [see also #20645, #20646 ]. These animals look kind of halfway between the other two. Markings are more reddish than green but they lack the white specks and don't appear to be transparent.
Locality: Browning Pass, 15 meters, British Columbia, Canada, Pacific, 27 August 2007, Rock Wall. Length: 3-6 mm. Photographer: Clinton Bauder.

Hate to admit it buddy, but I cannot ID this critter. Just can't see enough detail. Does anyone else have any idea?
Thanks, I guess,
Hi Dave, Clinton,
Bernard Picton has long held that species of Doto are very specific about the hydroids they eat. This animal and the two other spotted ones [#20645, #20646] each seem to be on a different species of hydroid. Perhaps it might be an idea to take a good photo of the hydroid colony when photographing species of Doto. It may lead us to an easier way to identify similar looking species.

While at at the oil Rigs off San Pedro, California, USA in April 2004 I found this Hallaxa chani with an Isopod

From the shape of the gills and the opaque colour I don't think this is Hallaxa, but I admit defeat with the California 'sea lemons' so if anyone can identify this I would be grateful

Here is another shot of Diaphorodoris lirulatocauda, this photo showing a slightly different angle for detail on the rhinophores.
Date = June 6, 2003
Location = Whiskey Cove, Indian Arm, British Columbia, Canada
Terrain = wall
Depth = 20 feet
Temp = 50 degrees farenheit
Equipment = Nikonos-V, 1:1

Your photo shows swollen tips to the dorsal papillae, which is not what I would expect to see in Diaphorodoris lirulatocauda. Onchidoris muricata has rounded tips to the tubercles but they seem to be of a rather different nature. I would be grateful for some comments from those of your familar with these animals

Thanks for your help on that Fijian nudibranch. Your the man! Here's one that I photographed last fall. My very knowlegeable friend and mentor Donna Gibbs (you have at least one photo of her husband Charlie under the Ancula Pacifica)has suggested it to be a triopha. Have you seen one of this coloration before?
Location: South Boyer Mooring Buoy, Howe Sound, British Columbia, Canada
Depth: 45 feet
Temp: 51 degrees farenfeit
Date: 1 Nov 2002
Found on top of a pinacle on solid rock
Equipment: Bonica Multi (closeup)

This certainly could be a species of Triopha. Perhaps someone will recognise it for us

I was in Salt Point, California, USA on Feb. 9. It's located on the coast in Northern California. While looking at tide pools during a negative tide I came across a large orange "slug" on the sandy bottom of one of the pools. It measured aprox. 20-25 cm long and was 14-16 cm around. It resembled a common garden slug, but was dark/burnt orange. I can't seem to find them in any of the sea slug web sites. Do you have any ideas as to what this wonderful creature could have been?

It is very difficult to identify things without an illustration. From your dimensions it sounds as though your 'slug' might be a sea cucumber or holothurian. Have a look at the Sea Cucumber page. Another possibility is the large chiton Cryptochiton stelleri. Have a look at Peter Firminger's message for some links to some photos of that species.

In California the Black Turban snail is Tegula funebralis. There is an entire supplement to The Veliger dedicated to the biology this species. As I recall it is comprized of class projects done by Hopkins Marine Lab Students. I don't know of a Black Turban sea slug.

Dear Bill and Tom,
The black turban snail in California is Tegula funebralis>. There is extensive information on this species, its feeding behavior, feeding preferences, population structure, etc. in the scientific literature (Ecology, Veliger, Journal of Exp. Mar. Biology & Ecology). Sorry, I have never heard of the Black Turban sea slug.

I would appreciate any information you could send me regarding Black Turban Sea Slugs that are found in the Carpenteria Area of California.

The name is not familiar to me but perhaps someone from California will know what a 'black turban sea slug' is. There are intertidal snails known as Turban Snails (Family Turbinidae) - but I don't know of slugs with that common name.

Do you have any information on the Cannibal sea slug? I got the name Cannibal sea slug from the Kelp Forest. The Cannibal slug lives in the Kelp Forest,

I'm afraid I am not very good at common names. If you are lucky someone may know which slug has been given the name 'Cannibal Sea Slug'. If it lives in kelp beds it may be a name for Melibe leonina but otherwise I have no idea.
