Gary Cobb This is Hypselodoris tryoni (Garrett, 1873) The genus was changed recently.

Gary Cobb Please try to converse in english so we all can read the message thank you.

João Pedro Silva Although that will prevent the use of automatic translations which will drastically reduce the number of "comic reliefs" we need on our daily lives.

Giorgetta Massimo Max ok thanks Gary Cobb

Gero Rinaldo nudibranch: Risbecia tryoni - Lembeh strait (North Sulawesi) Sony DSC WX1, f/2,4, 1/100 sec., ISO 1/160

Fadhel Ashka Risbecia tryoni nudibranchs [No Post Processing] Marine life fans would opt for seeing dolphins, sharks, turtles, and the big fishes, but these extremely colorful species that go by the name, nudibranches, fail to be in any fan's list. These creatures are so slow in the water, you can leave them and seek your buddies and bring them back to the nudibranches location without worrying about these creatures going anywhere. The front antenna are believed to work as taste buds and the back ones are gulls, just like the fish gulls. Believe it or not, some of these nudibraches are intoxicating.

Sonja Ooms A well fed tryon's risbecia. Puerto Galera, Philippines

João Pedro Silva Hypselodoris tryoni. Risbecia tryoni is no longer a valid name: http://www.marinespecies.org/aphia.php?p=taxdetails&id=558642

Sonja Ooms Yeah well as if it isn't complicated enough as it is. Makes it only more difficult for amateurs like me to identify an object. The identification for me as photographer is important in the sense that I can do some limited research on the object to get to know it better and to find it more easily. It also helps other photographers to find it and add it to their photo collection. But thanks anyway for remark, I will keep it in mind. Maybe you can give me a tip where to find a kind of list where they mention changes of names. I am specifically interested in nudibrancs.

Lisa Kelly Great shot!

João Pedro Silva With the Sea Slug Forum closed and lack of regular updates on Nudi Pixel, the best way to keep updated is through WoRMS (world register of marine species). There are also some groups on Facebook like Nudibase - sharing Nudibranch knowledge, but it depends a bit on which part of the world you're interested in.

Scubashooters Dot Net Welcome Sonja!!!! :)

João Pedro Silva My advice is to use whichever tools (guides, websites) you're used to for identification and then check for the validity of the names on WoRMS. There's an important aspect of correct identification which is often underestimated, especially important in good photos such as this one: other photographers and even amateur naturalists may find these photos on web searches as examples of the species and that may propagate on the web reinforcing the misconception. There are some more "scientifically oriented" nudibranch groups on Facebook but are also focused on some geographic region so it depends a lot on where you usually dive. For instance, the most active group is dedicated to NE Atlantic species (extending into the Mediterranean).

João Pedro Silva Medslugs may not be exhaustive for every region (it's not as the name suggests limited to the Mediterranean) but has many species and the nomenclature is updated: http://www.medslugs.de/

Gary Cobb Resbecia tryoni this species like to trail each other! Nice photo.

Ashley Missen Agree with Gary. Where did you find this guy as I have only seen them at Byron bay. Can you send the pic and sighting data to data@nudibase.com so I can add to the database cheers ash

Ashley Missen Hey Gary isn't that spelt Risbecia tyroni

Gary Cobb Nice try...Risbecia tryoni (Garrett, 1873)

Carole Patterson Hi Ashley, Can you please take me off this list? Cant keep up with what I get now. :) Thanks, Carole

Mike Bartick shot it in the PI, does that count?

Ashley Missen PI ?? Nudibase is global would love more from overseas

James Padfield I have a couple of pictures of Resbecia tryoni (not as good as this one mind!) from Vietnam a few weeks ago. What is this nudibase of which you speak?

Ashley Missen A website that tracks and Ids Nudibranchs www.nudibase.com you can send data into data@nudibase.com cheers Ash

Blogie Robillo Wait... I thought this had already been reclassified as Hypselodoris tryoni?

Ashley Missen Yes It has Blogie this is just an old post that's all that has be commented on recently

Massimo Corea chromodoris kuniei

Edoardo Spacca grazie!!!!

Roy Arthur David Lontoh I would say both are Risbecia tryoni ;)

Edoardo Spacca well, funny enough it seems there is little ambiguity as on some pics on the web it is also classified as chromodoris leopard.....

Orietta Rivolta Chromodoris leopardus has the black spots are quite large and several of them are hollow. By contrast, Risbecia tryoni would have more numerous smaller black spots with no white centres.

Ken Thongpila I would say Risbecia tryoni as well... I saw them in Tulamben too. Nice shot with 2 together :-)

Ashley Missen They are Risbecia tryoni - Chromodoris leopardus has dark circles not spots - nice double front shot - Cheers Ash

Gary Cobb HEY EVERYONE! When posting photos of Nudibranchs with names always use the whole name i.e.. Risbecia tryoni not R. tryoni. You only use the abbreviated name after you have used the whole name in any particular list or article.

Nadia Chiesi Info, this is Risbecia tryoni or Chromodori tryoni .... or ??? Thanks ! Photo in Dumaguete - Philippines

Mactan Cebu Scuba Chromodoris leopardus (Rudman, 1987) Depth: 10m Mactan, Cebu, Philippines

Ashley Missen This is a Risbecia tyroni as Chromodoris leopardus has small rings not dots - Great shot -Cheers Ash

Patrik Good Risbecia tryoni not tyroni (if it's not C. leopardus which is a hard call in the first place)

Mactan Cebu Scuba Thanks, guys.

Ashley Missen And thank you Patrik for the spell check

Gary Cobb Sorry guys you both are wrong! This is Hypselodoris tryoni (Garrett, 1873) according to the new research done. And to the person who thought this was Chromodoris leopardus Rudman, 1987, the author does not have (brackets)! The genus was never changed!

Gary Cobb C. leopardus has rings and H. Tryoni has solid spots.

Ashley Missen Has that paper been published yet as I didn't think it was a finish document yet - too many inconsistencies

Blogie Robillo I'm confused... Has Risbecia tryoni been renamed to Hypselodoris tryoni, or is H. tryoni an altogether different species?

Ashley Missen Same species, there is a paper out that is talking about resorting and grouping the Chromodoridae family

Blogie Robillo Oh right. I did download that document. However, since you and Gary were saying that it wasn't final yet, I didn't finish reading it...

Gary Cobb Richard Willan has said we have to abide by these latest finding. The technique is new and very conclusive. Bill Rudman said for a long time this would happen and it has. Yes some of it is incomplete but most of it proven by DNA not the traditional "comparing" of morphology and internal parts. I have made 62 changes to the New nudibranch ID Australia/NewZealand App and will upload the update this week. Its a pain in the ass but... (the paper has been accepted by the scientific community including Richard Willan.

Nerida Wilson Hi, just like to add that just because a paper is published does NOT mean that its accepted by the wider scientific community. It has been accepted by one or more reviewers (in PLOS one journal). I think that many of the groups presented by Johnson & Gosliner are correct, and a better reflection of the evolution of the group, but the tree is not particularly well-supported. So there is definitely a need for more data. And more discussion. That's how science should work.... cheers

Blogie Robillo In view of all this, which online resource do you think can be the most trusted in terms of nudibranch nomenclature?

Nerida Wilson To be honest, its a bit of a mess right now. Sites like the World Register of Marine Species have only made part of the changes suggested by this recent paper. Not sure if they don't like some of the results, or they just haven't finished yet.... Everyone needs to be patient, and remember...a rose by any other name!

Mactan Cebu Scuba I just love to take pictures. ;)

Blogie Robillo Are these Chromodoris kuniei? Spotted this pair at about 50ft at San Juan Reef, off the western coast of Samal Is., Davao, Philippines; 29 Jan 2012.

Alicia Mirabilis Surely not chromodoris kuniei... maybe risbecia tryoni

Alicia Mirabilis btw kuniei is the one in my profile pic ;)

Gary Cobb No these are Risbecia tryoni Garrett, 1873
