Northwest Nudibranchs

[Jan K]

Great find Janna, I forwarded this link to my Slug friends- they love it !

I was shooting an Opalescent Hermissenda crassicornis last weekend and I totally missed seeing a couple of nudis the size of a pinhead.

Here's another image showing two of them

Any idea what these are? Some kind of doto perhaps?

To all of you who are posting and identifying nudibranchs', THANK YOU!!!!
I just love them, and am totally getting a lot out of this thread. Please keep it up!

One of the most common nudis on the west coast, the Peltodoris nobilis or noble dorid, noble sea lemon, and a host of other names. This guy was actually on a big rock by the pipeline in Monterey Bay. I post him because you don't often catch one of them relieving himself like this guy is doing. I can't imagine having my waste products exit through my lungs, but it seems to work for these guys.

Dan, This one is a good one! I was pretty sure they weren't Dotos but couldn't put a handle on them so I consulted with Dave Behrnes on this one and was a little suprised to hear his opinion as to what they are. He said "I cannot say for certain, but I am pretty damn sure this is the Sacoglossid - Hermaea oliviae. Page 48 bottom"

Isn't fun to find something extra in a photo that you didn't know was there!

[dphershman]

sacoglossid opisthobranch Hermaea oliviae and not a nudibranch? I guess I need to get the 2nd edition of Behren's book!

thanks,
Dan

Naw just a BIG hurkin magnifiying glass! Although the book is highly recommended reading

Agreed on both counts, though I like the section on rhinophores and plumes in Dave's older edition better than the new one. With scanners being so cheap and libraries so handy, that's not a problem though

[spatman]

anybody have an ID for this one? it was tiny - maybe about 1cm. thanks.

[Dusty2]

Yep< It's an opalesent, Hermissenda crassicornis. The orange blase down the center of the head and the shape of the mounth horrns are dead give aways

Catching up a bit late. Bob, these photos are absolutely stunning.

Great shots, Bob! Man, am I sorry not to have been able to make that trip!

Here's a couple of shots of Dorids that I particularly enjoy. Please single click on the image for a larger, clearer view:

Although the dorids are easy for me to get confused on species, because of the black spots and white gills I believe that this is a Noble Dorid, Peltodoris nobilis. If that is not correct, I'd appreciate feedback on the correct species. It feeds on a variety of sponges.

Here's a shot of a Peltodoris lentginosa, or Freckled Dorid, named for obvious reasons! This species also feeds on sponges.

[John Rawlings]

I've been going through some of my old shots taken with film (egad!) Here's a shot taken years ago up in the San Juan Islands of a Flabellina verrucosa, also known as a Warty Aeolid. According to the "Nudibranch Bible", Eastern Pacific Nudibranchs, by David Behrens and Alicia Hermosillo, this species feeds on hydroids. Single-click to expand for a clearer view.

This is a photo of a Janolus fuscus. A species which I consider to be one of the most beautiful nudibranchs in our waters. This shot was taken years ago on one of the pilings at the Edmonds T-Pier, soon to be destroyed, which I guess is "progress".

Another film shot of a White-lined Dirona, Dirona albolineata, taken a long time ago on a dive in the San Juans. The White-lined Dirona feeds on bryozoans, hydroids and ascidians. This particular photo has always reminded me of an old "Clipper Ship" with all of its sails deployed:

Beautyful shots Bob, Sure wish they were here in the sound.

John, Love that freckled, Also one I have never seen.

You are correct on this one. The white gill plume is a good clue. Also if you look close you will see that the black spots do not extend onto the tubricles and the tubricles appear flat on top.

A nice clown nudibranch

A heath's dorid

And two Doto Columbiana the last with it's eggs

Hey Guys, What happened to all those pix?

Here is a pretty Golden from Friday at redondo

[dwashbur]

Where at Redondo? We've been wanting to see one of those for about 2 years now...

[cardiver]

And here's one at Les Davis....

By the time you get back up here it won't matter They are very transient critters. They usually only show up for a week or two and disappear again. Where they are the rest of the time????

I was diving at keystone jetty on Saturday morning and spied this 'Three Lined Nudibranch" Flabellina trilineata


I was happily shooting away when this scalyback sculpin decided to sit on my subject-- wouldn't get off either!
