Thuridilla splendens

Gary Cobb Here is Thuridilla splendens (Baba, 1949) laying its egg mass on the Halimeda leaf. It was very careful not to go over the edge!! Nature is perfect!

Ashley Missen Freaky - cool photo Gary Cobb

Gary Cobb Perfect! And without eyes!

Gary Cobb This species is one of our most common.

Ashley Missen nature amazes me all the time

Roxanne Fea That's like installation art...

Gary Cobb I was lucky to be there!

Christopher Thorn Thuridilla splendens? Green Island, Taiwan. 20 mm, 3 m.

Cynthia D. Trowbridge Elysia marginata (species complex) based on our molecular evidence from Okinawa and elsewhere

Christopher Thorn interesting , thank you.

Andy Gray Well it looks like a Plakobranchidae but not sure its what you think it is. Maybe a Rough Elysia or an Ornate Elysia. Hard to say from the pic.

Christopher Thorn if i understood Cynthia correctly Elysia ornata is considered part of the species complex. Do you have a latin name for the 'rough elysia' Andy?

Andy Gray No they just call it an Elysia sp. There is an awful lot of them too. A lot of different looking Elysia ornata also. http://seaslugsofhawaii.com/species/Elysia-ornata-a.html

Gary Cobb We are calling this Elysia ornata

Cynthia D. Trowbridge Gary, we have a paper in the final stages...there are no ornata in the Pacific and there are many in the marginata complex. This is one of them. So, what people are calling ornata in the Indo Pacific are marginata sensu lato and need to be redescribed and renamed....

Amruta Prasade We have also found these type of Elysia sp from Gulf of kutch, Gujarat which we used to call Elysia ornata. I have shared its photo in my older posts.

Gary Cobb Nice work please send me the paper please please please:)

Gary Cobb Correction: Halgerda sp. 2 is correct.

Gary Cobb We had a surgy couple of dives at Flinders Reef Moreton Island yesterday and found 26 species. Here is David Mullins, me and Jo posing at the surface interval in our new H1 Hybrid Waterproof drysuits, very warm aboard Mischief.

Gary Cobb Here the list of species we found: Berthellina citrina Chromodoris aspersa Chromodoris elisabethina Chromodoris lochi Cratena lineata Cratena simba Chromodoris burni Costasiella kuroshimae Doriprismatica atromarginata Elysia sp. 1 Goniobranchus collingwoodi Goniobranchus cf. verrieri Goniodoridella sp. 2 Hypselodoris whitei Plocamopherus imperialis Phyllidiopsis burni Phyllidiella pustulosa Phyllidiella lizae Risbecia godeffroyana Roboastra gracilis Thuridilla livida Thuridilla neona Thuridilla carlsoni Thuridilla gracilis Thuridilla splendens Trinchesia sp. 8

Patrik Good Congrats, good work. The variety of Thuridilla is exciting. With a few of the species I was not sure if they have just changed their names or if I just haven't come across them yet (eg. had to look Dori-S-prismatica atromarginata up).

Gary Cobb Sorry these suits are D1 species not H1!

Gary Cobb Patrik where did you find the spelling with an 's'? I had a re-look at the paper and it is spelled Doriprismatica, -> no 's'. Thanks! Yes we find quite a few Thuridilla at Flinders Reef.

Jim Anderson Your new suits are the business - I've been diving in one for 10 months, even down to 6 deg C. Not a problem your likely to have.

Gary Cobb Patrik the spelling of Doriprismatica is correct according to the paper.

Gary Cobb Hey Jim so you have a Di Hybrid?? Nice work. I love the suit!

Patrik Good Sorry Gary Cobb. Here the link I got it from: http://clade.ansp.org/obis/search.php/3587

Gary Cobb Patrik I think this site is old. It is saying Dorisprismatica is a synonym.

Gary Cobb I have written to Richard to get verification.

Ashley Missen Is there an email version coming out

Gary Cobb See thread above!

Gary Cobb 27 species actually!

Blogie Robillo Having a hard time determining its species: is it Thuridilla splendens or Thuridilla gracilis? Length abt 3cm; depth 23m @ San Juan Reef

Gary Cobb This is a colour form of Thuridilla gracilis. The Forum has photos of this colour form. T. gracilis usually has lines on the sides of the body where as T. splendens has spots and sometimes those spots inter twine with a reticulate pattern with larger blue spots. These guide lines are a general way to guess the difference between the two species. Having a look inside will determine species. How this helps! :)

Blogie Robillo Thanks for the helpful info, Gary, as always! :)

Gary Cobb You're very welcome Blogie! Nice hunting.

Timothy Nguyen Thuridilla splendens? Flinders Reef, Moreton Island @13m, 30-40mm https://www.facebook.com/photo.php?fbid=10150596096851334&set=a.10150596089821334.377975.562001333&type=3&theater

Gary Cobb Can't see the photo!:(

Timothy Nguyen Changed the privacy setting on the album Gary Cobb, can you see it now?

Patrik Good Yep and yep from me.

Gary Cobb Yes I can see the most common Species of Sacoglossan here. Thuridilla splendida (Baba, 1949)

Patrik Good Even if you spot 50 of them on a dive, still check them out as one of them might turn out to be a Thuridilla gracilis which I would like to see again soon.

Blogie Robillo Help with ID, pls? This is a species of Thuridilla, yeah? Length abt 2cm; depth 28m @ Marissa 1 dive site

Ashley Missen Thuridilla ??

Blogie Robillo Yeah? It looks somewhat like Thuridilla lineolata, but not really... http://www.nudipixel.net/species/thuridilla_lineolata/

Gary Cobb This looks like a colour form of Thuridilla splendens

Gary Cobb This species is very variable!

Blogie Robillo I see. Thanks, Gary!
