Verruca stroemia

O.F. Müller, 1776


Erling Svensen Could this be some kind of barnacles? Norway yesterday evening.

Marco Faasse Sure! Verruca stroemia. Here we call it (translated): zipper barnacle. You see why :-)

Erling Svensen Thanks a lot Marco. A new species on the list. Need to buy a botle of red wine......

Jane Pottas I recognise them as V. stroemia but I like the name zipper barnacle!

Marco Faasse Congrats, Erling! Keep searching. Always good to find a reason to open a bottle. If I can help to find new species ...

Erling Svensen You are welcome to Norway to help searching.....

David Kipling Ian ... that flickr set is excellent, the way you use the embedded dynamic annotation of the pictures is great, not seen that before!

Ian Smith Thanks David. There have been big changes to Flickr recently: Free storage for about half a million images per person. All users can now arrange images in "collections" of "sets" for free. Sadly the "collections" button is hard to find; users need to click on the 3 dots at top right to get a drop down menu with it on. My collections (barnacles - set each for the 9 littoral UK spp. and gastropods - set each for 4 small spp. ;more to come) are at http://www.flickr.com/photos/56388191@N08/collections/

David Kipling Erling's zipper photo for Inga Williamson, plus do have a look at Ian's flickr album, it has some cool feature. Oh, and welcome to Seasearch ID ;)

Inga Williamson Thanks David - great picture indeed

David Kipling Ian, Erling ... I've never seen these in the UK but there are loads of records. What sort of depth/habitat do you find them?

Ian Smith Low water, Fucus serratus zone downwards. Often on F. serratus and often UNDER stones - look crushed. On Menai Strait often common but invisible under sponge, except for red gape when open. I found a Lamellaria perspicua with a good imitation of the gape and sponge (pic on Conch Soc site). Verruca stroemia is such a distinctive sp. with its chevron pattern of grooves/ridges that I think records will be ok, but a similar Verruca sp. in Mediterranean needs inspection of underside of opercular valves to differ.

David Kipling I shall have to have a hunt!

Ian Smith Southward says to 500 metres. Moment of self doubt -I THINK it occurs on F. serratus, but my memory might be confusing it with Balanus crenatus. Will check on my next visit. Certainly likes under stones, but not exclusively.

David Kipling 500m deep?!?

Ian Smith Well NBN does have a saltmarsh sp recorded on the Brecon Beacons :-)
