Sidnyum turbinatum

Penny Martin ???

David Kipling We saw some that looked like they might be the same sort of squirt as this, but above-water. See album I've just posted.

David Kipling Sidnyum turbinatum? "Typically a member of the exposed sublittoral fringe/shallow infralittoral communities." Has been recorded in Orkney. http://www.habitas.org.uk/marinelife/species.asp?item=ZD520

Penny Martin hey yes ...... they are very pretty little squirts !!

David Kipling Aren't they just ;)

Penny Martin better than Paula's ciona !!! :-)

Erling Svensen This one must be the Sidnyum turbinatum (yesterdays dive). But the next one?

David Kipling Nice to see the stalks of these - I'm used to them emerging from silt-covered rock faces. But yes, Aplidium turbinatum (it's changed from Sidnyum).

Erling Svensen WHY do the names change all the time. Frustrating, and not nice to all my pictures.... I HATE also this. Nice the weather is so nice and warm outside and that my holiday starts in 2 days....

David Kipling http://data.nbn.org.uk/gridMap/gridMap.jsp?allDs=1&srchSpKey=NHMSYS0020752559

David Kipling And it's also Aplidium elegans (not Sidnyum) and NBN has it as Aplidium elegans too.

David Kipling I dare say it is set up so that it recognises accepted synonyms and corrects it for you. Paula Lightfoot?

Jon Chamberlain White squirt being photo bombed by what? Prizes for naming either... http://www.flickr.com/photos/underwaterinferno/8072334201/in/set-72157631733973528/ Beadnell Point, Northumberland 7m rock wall

David Kipling I think it's starting to regress for the winter so looks a tad weird. For a white polyclinid how about Aplidium turbinatum as a starting point?

David Kipling (I assume 7m refers to the depth recorded?)

Jon Chamberlain Yep

Bernard Picton I think Aplidium nordmanni. Sidnyum turbinatum always forms small separate lobes.

Bernd Lipsius

David Kipling At least three species of sea squirt there I think ...

Bernd Lipsius amazing what you can see in this hazy and unfocused picture

David Kipling I'm guessing the peach-coloured lumps in the middle are Sidnyum elegans, and then down in the extreme LHS there are a couple of small patches of what I think is Sidnyum turbinatum. And then middle LHS there is a red siphon, which could be just about anything!

Liz Morris Thanks for the ID tips guys - good spotting Bernd.

David Kipling Am I right in thinking that I should be referring to Sidnyum (eg elegans, turbinatum etc) more properly as Aplidium? http://www.marbef.org/data/aphia.php?p=taxdetails&id=103441

David Kipling Actually it's Aplidium on NBN: http://www.searchnbn.net/gridMap/gridMap.jsp?allDs=1&srchSpKey=NBNSYS0000177968

David Kipling Same is true for Aplidium elegans as well ...

David Kipling This probably explains why there are no records for these species in Norfolk ;)

David Kipling We have every intention - roll on Aug!

David Kipling Kate Lock and my carer are certainly coming. Does Becky Hitchin know about this as well?

David Kipling A week of squirts should temp Becky out of Kent ;)

Kate Lock Lalalalalalalalalalala I am with Dawn Watson on this one......

David Kipling So Kate and Dawn ... doesn't marine recorder beep an error at you when you try and enter Sidnyum (since it's out of date)?

Kate Lock I hate databases....and MR does not like Macs and I like Macs so I kindly pass on all the forms to that nice Jennifer Jones to do the MR entry and earn some extra winter holiday money!!

Jennifer Jones No David, it accepts Sidnyum but not Aplidium

David Kipling Aplidium nor Sidnyum on NBN and WoRMS... argh!!!

David Kipling But which is correct?

Paula Lightfoot According to WoRMS Aplidium is accepted and Sidnyum is unaccepted. MR will get there! http://www.marinespecies.org/msbias/aphia.php?p=taxdetails&id=103683

David Kipling Dawn's going to go all punk and rebellious on me and stick with Sidnyium now!

Becky Hitchin I'm sure I've managed to enter Aplidium into MR!

Paula Lightfoot Aplidium elegans is in the MR look-up table (since Nov 07) but Aplidium turbinatum is not, only Sidnyum turbinatum.

Becky Hitchin and Aplidium punctum is in there I think?

David Kipling And hopefully Aplidium glabrum, nordmanni and pallidum?

Paula Lightfoot yes yes yes and yes! but I don't think punctum ever was a Sidnyum, whereas elegans and turbinatum were...I think...I'm getting confused by all these squirts!

David Kipling For those of us who use Habitas, it's really only these two Sidnyum/Aplidium species that are different between Habitas and NBN. Phew!

Jennifer Jones I wasn't saying Aplidium spp weren't recognised in MR, I was talking specifically about the species mentioned!

David Kipling I know, we just got paranoid Jen ;) Having spent way too long today going through every ascidian entry on NBN I am now a little spooked by just how many Didemnum species have been recorded in the UK. Those are going to end up in a "flat sheet with holes" category at this rate (alongside "thin orange crust", a phrase that covers a multitude of sins...).

Jennifer Jones Now maybe you understand why I won't name a lot of sponge crusts without thorough investigation!

Becky Hitchin At least D. vex is included in MR now :)

David Kipling But no map data on NBN, correct?
