Kim Foss-Pedersen Hello evryone! I need help to find out the name on this one. Found it in the oslofjord (Norway) on 4m the size is around 3-5mm.

Klas Malmberg Aquatilis Placida dendritica

Guillem Mas Looks like Placida dendritica.

Kim Foss-Pedersen Thanks :D

Yara Tibirica More one to ID pls, 9mm Zavora, Mozambique

Lucas CerCur It seems like a Placida...

Brendan Oonk I agree: it looks like Placida dendritica

Cynthia D. Trowbridge "Placida dendritica" is a collection of a large number of described and undescribed species... I have said this for a long time (at conferences and in print) and now molecular evidence has supported it (published work in Asia and unpublished work elsewhere). This issue was also acknowledged in the Indo-Pacific book by Gosliner et al. So tred carefully with the species name unless you are near the type locality in England :-)

Brendan Oonk Thnx for the info Cynthia, didn't know this about Placida dendritica. Must not have been paying atention ;) By the way, i didn't mean to say that this nudibranch IS Placida dendritica, just that it looks like it, so Yara has a starting point, for finding the species name. I will be more carefull the next time, in using species names :)

Yara Tibirica Thank you all, sorry I left all the trick spp to post here :) I also think is a Placida, I will leave it as Placida sp. for now. Cheers.

Cynthia D. Trowbridge In Japanese sea slug books, the name Placida dendritica has been used for photos of at least 2-3 genera and many, many species. Shape of cerata, rhinophores, and pericardium are important differences as well as branching of tubles in the cerata, shape of radular teeth, morphology of reproductive system, size of ova, capsules, and larvae. DNA is much easier...

Ajiex Dharma Stilliger??? Found in 15m deep,adult size. Tulamben Bali

Kati Burg Looks very interesting!

Ajiex Dharma Thanks Kathrin,do you know the ID name about this nudi??

Kati Burg No, I don't know. I haven't seen this one before. Great photo. Cool how you can see thru the filaments.

João Pedro Silva Hermaea sp.

João Pedro Silva Technically, not a nudibranch but a sacoglossan... which some researchers now think may be closer to pulmonate gastropods than to opistobranchs.

Blogie Robillo Wonderful!!

Ajiex Dharma Thanks Blogie Robillo :)

Orietta Rivolta Wondrful nudi,great find!

Ajiex Dharma Thanka Orietta Rivolta, when would you like to come to Bali?

Orietta Rivolta Maybe next year :-))))))

Floor Driessen Isn't this a Placida dendritica?

João Pedro Silva I don't think this is P. dendritica, Floor. This has black tips of the cerata (clear in P. dendritica) and it's outside the distribution range.

Mark Farrer Blairgowrie 28/1/12 5mtrs approx 30mm long

Ashley Missen what an interesting critter

Mark Farrer Any ideas as to what this critters name is

Ashley Missen I working on it

Carolyn Thomson Cute

Ashley Missen I am going to call mr greenandgoldsquiggly

Mark Farrer So that means no luck with the offical name so we will now refer to the unofficial name of greenandgoldsquiggly.

Gary Cobb I think this could be Placida dendritica

Mark Jones So where was I when you got this one?

Mark Farrer I think I have another angle of this critter Garry i will try and dig it out and post later to see if that makes you more positive for the ID.

Mark Farrer Unsure as to where you were buddy I did post in here at the time but trying to get names for my Nudibranchs.

Mark Farrer Blairgowrie 28/1/12 in 5mtrs

Ken Thongpila Another nice found Mark Farrer.... Love it... Ashley Missen another list please :-)

Mark Farrer Thanks Ken it was a fantastic dive for me personally theseare some of the first images with my new set up and these Nudi's made it very special only thing missing was my full time dive buddy's who missed out.

Mark Farrer Do we have an ID for this little Nudi was only about 40mm

Antoni López-Arenas Cama Maybe Placida dendritica?

Ajiex Dharma Stilliger sp?? This is adult size found at 15m deep.Tulamben Bali. Special thanks to Indra Swari W.

João Pedro Silva Except for the black spots on the cerata I'd say Placida dendritica. It's most probably one of the Hermaea sp. Richard Willan identified on Nudipixel: http://www.nudipixel.net/photo/00034944/

Ajiex Dharma Thanks Pedro...

Paula Lightfoot Are these Placida dendritica? Taken yesterday at Grandes Rocques on the west coast of Guernsey.

Paula Lightfoot Actually this was taken on today's dive - I'm getting my days mixed up!

Kate Lock wow that is what I call serious camouflage!

Cynthia D. Trowbridge Yes, these are specimens of Placida dendritica :-)

Cynthia D. Trowbridge Beautiful photograph as well

Rudolf Svensen Lucky you. I have been searching for those but with no luck so far. Nice photo.

Pippa Swannell Great pic. Is the algae Codium fragile? I see Elysia viridis all the time on Codium in Devon but could I find this beauty if I look harder?

Erling Svensen They are quite common in Stavanger where Rudolf live.... ;-)

Rudolf Svensen Never seen them and I have been looking for a long time, but one day I'll find them.

Geoffrey Van Damme Blairgowrie 15mm thecacera pennigera ,and i think the small green one is placida dendritica 5mm.

Patrik Good Missed your posts Geoffrey. Glad you are back with a bang.

Lucas CerCur Another good project: Is the same species all that is named Thecacera pennigera around the World?

João Pedro Silva Only found it once here in Portugal but apart from the size of the spots I cannot see any differences. It's most likely to have some internal differences (thinking about the radula here) as its diet will probably vary according to local availability. Further studies would confirm (or not) if its the same species and also confirm (or not) the theory regarding their spread around the world. http://www.flickr.com/photos/jpsilva1971/6911346679/

Geoffrey Van Damme Thanks Patrik Good ,nudis have been scarce here at Blairgowrie for a few months ,seems to happen when the water warms over summer .Temp is getting down again now and nudis are starting to show again so hopefully will start to find some new ones again.

René Weterings OLYMPUS DIGITAL CAMERA Rene Weterings

Cynthia D. Trowbridge On red algae or green? Looks like red in the photo... this species eats algae from at least 7 genera, native and introduced, green and red.

René Weterings I think both. But what we do see here is that a lot of specimen are almost yellow and don't have that distinctive green color from which we know them. What causes that?

Cynthia D. Trowbridge When I raised them through their life cycle (in Scotland), the new juveniles were yellowish (with some blackish pigmentation) until they fed. Therefore, I presume that your animals are starving (no more fresh food and retained chloroplasts breaking down). Although the species eats many algal species and genera, individual slugs do not readily switch....so perhaps like Placida dendritica in Oregon, individuals of E. viridis could starve to death with food that sympatric conspecifics consume.

Floris Bennema It's funny they were there in big masses at the start of November, a prolonged explosion? All of them were green and some of them seemed to be too sluggish to be healty. From what we saw feeding on Codium fragile, their staple food.
