Elysia subornata

A. E. Verrill, 1901


Marlon Delgado Elysia ??? Natal RN

Carlo M. Cunha yeap ;)

Marlon Delgado I'm sure that It's an Elysia, but Elysia what? :)

O Gajo Dos Olivais Could it be Placida cf dendritica? It looks like it has a group of cerata...

Hilton Galvão Filho Its seems To be Elysia subornata! It has the same external features of the specimens from the type locality! However I need to see others characters to confirm this.

Vinicius Padula MahLeco, I agree with Hilton Galvão Filho. In the link below you can download a paper on this species, based on one specimen from Cabo Frio https://www.dropbox.com/s/amysg1zyjqk1bj1/Padula%202008%20Sacoglossa.pdf

Cynthia D. Trowbridge Many distinct species (based on molecular evidence) of Elysia look similar to this externally. I would urge caution rushing to an identification based on external characters.

Hilton Galvão Filho Absolutely. We can't forget to analysis all the anatomic data too. Similar specimens can be deeply distinc when we compare their organs and systems. Elysia spp. are known to have a common external pattern and a high anatomyc variation.

Ashley Missen A new Elysia sp. ?? for me under Blairgowrie Pier Victoria Australia 2 found 4m depth 25mm long 13 deg temp - any ideas people

Lindz Warren Possibly Elysia flava Verrill, 1901?

Chandy de Wit Elysia virdis? Have found them in Perth WA waters, 14 degrees from 3mm- 2.5 cm?? @ Around 4m depth in algal bloom.. That was the closest ID I could find ??

Lindz Warren I don't think so. E. viridis is supposed to be an Atlantic & Mediterranean species although it could have been spread. But the appearance of Ashley Missen's specimen does not seem to fit the description. See http://www.seaslugforum.net/showall/elysviri

Lindz Warren But I could be wrong ;-)

Chandy de Wit I just went with the first one that came up on nudipixel? My ID may be wrong but these look like the same Nudi???

Chandy de Wit This particular one was also 25mm, the largest we found here in the coolest months, they seem to have gone dormant with the rising water temperature?

Lindz Warren Sorry I meant to refer to Ashley's specimen and have corrected my earlier comment. Does Ashley Missen have another shot of the same specimen?

João Pedro Silva I think you're right, Lindz Warren.

Gary Cobb Elysia flava is a west Atlantic species I don't think this is that.

Gary Cobb The closest I could see is Elysia obtusa. The black margin does not fit this species. I would say Elysia cf. obtusa

Gary Cobb Strangely Ashs animal looks just like Elysia subornata from the west Atlantic!

Ashley Missen Thanks guys for the suggestion my dive buddy Danny will post some other angles

Kirstie Knowles Seeing Bob Burn next weekend Ash. Will show him the pics too if ok n add his suggestions to the mix.

Ashley Missen you might want to grab Danny's shot too

Gary Cobb After seeing the new photo this is Elysia expansa.

Ashley Missen Thanks Gary

Kirstie Knowles Hi Gary - for those of us learning can you explain why you think it's E. expansa? I didn't think they held their parapodia together like this? Thanks.

Gary Cobb Simple...when the animal is at rest the parapodia margins tend to "curl up". This has been my observation.

Gary Cobb The opaque white "frosting" on the rhinophores is characteristic. And the white frosting and black margin.

Kirstie Knowles Thank-you :)

Gary Cobb You're quite welcome!
