Its a spider crab

This is certainly a spider crab but my feeling is that its more likely to be one of the Hyas species rather than Macropodia which are much more slender in their body form.

The UK has a number of spider crabs and they are often difficult to tell apart and to do that you need to see the eyestalks, the rostrum the antennae and details of the walking legs. I can't see that detail on the image unfortunately

Hi Coloursofmemory, could

Hi Coloursofmemory,

could you edit this ob into invertebrates please? I think this is one of the much larger spider crabs like Maja brachydactyla, the Hyas species are quite small in comparison and not red coloured or spiny.

Definite

Definitely spiny spider, I'm with nightfly on both counts. Where are the Hyas species with spiny shells

Hi Chris, I think the Maja ID

Hi Chris,

I think the Maja ID was posted prior to various discussions which determined that all UK Spiny Spider Crabs were M. brachydactyla?

UKSI is still sticking to squinado

I thought the squinado preferable Cathal to link it to the other 'observations in the species' though I see there are now 5 brachydactylas on Ispot.

I noticed in google images 1 from woRMS page on araneus, at http://www.marinespecies.org/aphia.php?p=taxdetails&id=107322 , a bright pink photo clearly of a spiny spider,as shown by the rostrum (araneus is "2 tapered close-set horns" but maja "2 thick, forwardly directed horns").
