Hermaea variopicta

(A. Costa, 1869)


Richard Lord A Porcupiner (PMNHS) found this nudibranch on red seaweed at Portelet on Guernsey's south-west coast on 5 April 2012. Is this Hermaea variopicta? The individual was about 35 mm long.

Cynthia D. Trowbridge sacoglossan, not nudibranch

Richard Lord Thank you for the correction, Cynthia.

Bernard Picton OK Cynthia! Look I refuse to call this group NE Atlantic Opisthobranchia as the group description indicates it should be really!

Bernard Picton Richard Lord, sorry I just asked you to repost it here, not realising you already had. Can you add a lat long? Google Earth will give you one easily if you don't already have it. Stunning photograph - how did you do it?

João Pedro Silva You can also use Google Maps to get the coordinates.

Richard Lord I will need to ask Paul Brazier exactly where he collected the red seaweed that contained this sacoglossan - but Portelet on Guernsey's south west coast is at 49° 26 07 05 North and 2° 39 46 42 west.

Cynthia D. Trowbridge Hi Bernard, I just meant (above) that the initial message calling it a nudibranch was incorrect (which would be important for a first record for Guernsey). Some people understand the distinction whereas other people do not and think: sea slug = nudibranch. If you would not call a dog an ungulate or a deer a canine, then you should not call a sacoglossan a nudibranch. Closer to home, if you would not call a coral an anemone or a gorgonian a soft coral, then you should not call a sacoglossan a nudibranch. If the point of science is clarification and understanding, then lumping two distantly related taxa into one is not constructive.

Cynthia D. Trowbridge Richard, the photo is truly stunning and a spectacular find for all! Congrats to all the folks on the collecting trip. With more eyes looking at Griffithsia and Halurus, hopefully we will get more records of this wonderful Hermaea variopicta throughout the British Isles, Atlantic France, and the Channel Islands.

Carissa Shipman this is amazing! I am in love!

Dan Bolt Utterly amazed to see this Mediterranean species in south Devon (UK) today. I think it is Hermaea variopicta? I've seen it once before, just 20m from today's sighting but back in September 2008. Have a good weekend everyone :-)

Ian Smith Great find. It matches the description and illustration in Schmekel & Portmann "Opisthobranchia des Mittelmeeres" closely.

João Pedro Silva Yes, it's Hermaea variopicta. Although hard to see, it's also found along the coast of mainland Portugal.

Dan Bolt Thank you both for the confirmation :)

Sarah Bowen Wow - there certainly seem to be more and more non-natives turning up on the South Coast, don't there. I wonder if we should start to log these unusual sightings more systematically, and if so, where? Conch Soc perhaps? See further down for posts about Cadlina pellucida which turned up on the Manacles in September too!

Dan Bolt I always fill in a SeaSearch form for any weird stuff I see, they are building an awesome database of info for the whole of the UK

Sarah Bowen Yes, me and David Kipling are keen Seasearchers too! These 'weird' ones don't always make it onto Marine Recorder straight away because they're not yet on the UK databases. That's what makes it so exciting.

Ian Smith Hi Sarah Bowen the Conch Soc is very keen to have the southern arrivals on its on-line Encyclopedia so descriptions and images are available for recorders. I'm approaching finders of new species to ask permission for use of their photos when I am ready to tackle the relevant account- I don't want to ask and then keep them waiting. It is not always plain sailing - I've been trying to sort out one sp. for 4 months but seem to have run into the sand. I'm keeping note of relevant postings so I can approach folk. I've had very generous responses from those whom I've asked, and am very grateful, but I realise that some folk may not want their images used, especially if they have their own website. I hope I won't cause embarrassment to anyone by asking. Cheers Ian (editor of sea slug section of Conch soc Encyclopedia, and starting on the Cephalopods - have a look at the Sepia account using Joao's wonderful images, not quite finished yet)

Carissa Shipman Stunning!

Bettina Balnis what a beautiful nudi

Bernard Picton Great photo, Dan. This species has been found on a few occasions in SW England before, and we got it in SE Ireland once.

Paula Lightfoot Beautiful!! This species was recorded during the Porcupine field trip to Guernsey earlier this year too. Unlike Cadlina pellucida, this species IS in Marine Recorder so if you put it on a Seasearch form it'll go on the NBN Gateway.

David Kipling All you need now is for the Channel Islands to be on NBN Gateway Paula ...

Arne Kuilman Cool nudibranch!

Cynthia D. Trowbridge not a nudibranch :-(

Cynthia D. Trowbridge a sacoglossan...

David Kipling Vegan nudibranch ;)

Antonello Nazareno .... It is present here in southern Mediterranean ... but rather rare ...
