Halymenia latifolia

P.L.Crouan & H.M.Crouan ex Kützing, 1866


Paula Lightfoot Hi, does anyone have photos of the anemone Peachia cylindrica, the parasitic barnacle Sacculina carcini or the red seaweed Halymenia latifolia that they would be happy to share for use in the 'Name a Species' competition run by Natural England and The Guardian?

Peter Glanvill I have one that probably would be acceptable. Taken a year or two ago at Babbacombe. Where would you like me to send it?

Darryl Mayer Peachia cylindrica, the one with the W or M on each tentacle? I have some from a while ago too.

Paula Lightfoot That would be lovely thanks - I'll send a message with my email address!

Darryl Mayer Picture sent.

George Brown Hi Paula, got a couple of photos showing Sacculina carcini on a shore crab. Still need them?

Paula Lightfoot Hi George Brown, that would be great thanks - I've got a couple of lovely Peachias now but no Sacculina.

Andy Horton If you get really stuck for Sacculina, I am sure I have some in my slide collection. The quality might be naff though.

Paula Lightfoot Desperate last minute addition to this request!! Does anyone have a photo of Brissopsis lyrifera pleeease! (heart urchin found in mud/sand...possibly not so likely to be seen by divers?)

Darryl Mayer I'll have a look P. I think I do.

Darryl Mayer I have one, a dead one but nearly complete?

Peter Glanvill I have one I use in talks but the urchin is mostly covered in sand although on the surface - you can just see a few bristles.

Christine Howson I'm sure there's a Brissopsis picture int he MNCR sealochs collection
