Erling Svensen These tiny (1 cm long) mussels, may it be the Mytilus edulis - juvenil one?

Steve Wilkinson And looks like Irus irus over on the right (pinky siphons)

Erling Svensen I do think the one over to the right is Hiatella arctica - "stoneboringmussel" in Norwegian.

Erling Svensen There is also one in the centre of the picture.

Paula Lightfoot Mussel 3mm x 2mm - very hairy! Found on mid-intertidal rocky shore near Whitby. We wondered if it could be Modiolus modiolus or Modiolula phaseolina...but I've just read that Mytilus edulis sometimes have hairy spat too. Looking in Paul Chambers and Hayward and Ryland for inspiration but they don't say much about the spat.

Chris Barrett Are the hairs hydroids? Could be M.edulis if so

Bernard Picton There's a great bivalve site on the National Museum of Wales web pages: http://naturalhistory.museumwales.ac.uk/britishbivalves/browserecord.php?-recid=93

Andy Pange Sharkbait Richardson Looks like Modiolus barbatus to me

Steve Wilkinson I think Modiolula phaseolina. You can separate from barbatus by whether the spines as serrated on one side or not (phaseolina is not) and be absolutely sure if you can open it and look for the little pocket of crenulations - as per the link Bernard provided.

Paula Lightfoot Thanks everyone! The actual specimen is in the (i hope) safe hands of Royal Mail on its way to our Conchological Society Recorder right now so I can't open it up. It was found quite high on the shore, attached to a blade of Ulva lactuca. Andreia Salvador, Curator of Marine Mollusca at the NHM also thinks it is Modiolula phaseolina from the photographs.

Could it be a juv Modiolus barbatus

Chris Wood Diving Mussel Beds Horse mussel (Modiolus modiolus) and Blue mussel (Mytilus edulis) beds on sediment are both priority habitats and thus target areas for Seasearch diving. Recent Seasearch dives have targeted both types. In the Isle of Man Seasearch has dived a horse mussel bed off the eastern side of the island, which is currently unprotected but thankfully remains in excellent condition. In addition to a dense covering of horse mussels, the bed also has a variety of branching sponges, especially the yellow Iophon nigricans, hydroids and mobile animals such as hermit crabs, painted topshells, urchins, starfish and young fishes. The picture shows some of the variety of life that the horse mussel bed supports. Blue mussel beds can be quite transient, and a recent Seasearch dive with Sussex Divers on the coastal chalk platform off Rottingdean found the seabed and attached plants covered in a carpet of tiny mussels. Whether they will remain in the long term is questionable, but the starfish population was already responding to the new food source with large numbers of young animals, each only about a centimetre across. A similar mussel fall was also reported from Shoreham, a few miles further west, on Seasearch dives with Brigthon BSAC. In North Norfolk a blue mussel bed has been proposed as a Reference Area (no take zone). It is a tiny area only about 500m square and a couple of kilometres offshore and we covered all of it and more in our dive as there was a current of about 2kts running which made recording callenging. The bed was patchy, with sandy areas between the clumps of mussels, but they were also providing a habitat for dahlia anemones, common starfish, sunstars, crabs and the finger bryozoan.
