Description:

Amazing creatures! Shells are a Light blue/grey in colour. The soft, tubular body is attached to a washed up tree stump on a west Dorset beach. The body also appears to be far too big to be able to retract into it shell. Live; the bodies were an orangey/tan colour. Dead and very smelly; the bodies were black. The photo shows the scale against my hand. Any ideas what they are please?

The idea a long time ago was

The idea a long time ago was that Barnacle Geese developed inside these barnacles, and there are some lovely old woodcuts of the barnacles opened up with tiny but fully-formed Barnacle Geese inside. On the back of this fiction, the geese were defined as fish, not meat, so could be eaten on non-meat church-days.

As these are Invertebrates (Crustaceans), you should edit the observation to the 'Invertebrates' group (My spot, Observations, find this one, edit, and choose from the drop-down menu).

They are indeed British (or

They are indeed British (or at least found on UK shores after storms). They are open-sea pelagic animals on floating debris just as described.

Stalked barnacles

Stalked barnacles are more common than many people think and are frequently encountered on the west coat of UK on stranded material, usually logs. While species of Lepas (not always L. ansifera) are the most common there are a number of others.

According to Southward, in UK waters we have the following species of stalked barnacle that attach to floating log/ships etc

4 species of the genus Lepas
1 species of Dosimia
2 species of Conchoderma (on ships)
1 species Alepas (on jellyfish)
1 species Paralepas (on echinoderms)
1 species Pollicipes (rarely on seashore in Cornwall)
1 species Scalpellum (on hydroids and gorgonians)

There are a few other species associated with cetaceans and sharks.

You meant not always Lepas anatifera?

This will only change to invertebrates

This will now only change from fish to invertebrates if Kazzibird edits the post & changes the group to invertebrates or a lot of people switch agreements to the last ID

Unlikely

I fear Chris that's asking too much these days - people switching. And I am not certain shifting Likely actually changes the Group (for Fish particularly) as I think it's your new ID which now does that (magically).
I shifted my agreement, but of course it made no difference, so I've put it back.
Karen (Kazzibird) has almost certainly left the arena so it's up to Admin to put this right and WHY don't they for goodness' sake?
Ne'er mind, I do believe it's the Comment Trail that's more important - I re-read Syrphus', lovely!

Shifting ID (even with one

Shifting ID (even with one identical) does indeed switch the group, as I've just found today several times. It would take you & martinjohn bishop switching to the last ID, & maybe 1 or 2 more fish experts like nightfly (already there I see), as none of us are very good in fishes

Waiting

Yes, I think Cathal (nightfly) could swing it (I've tried). He is normally quite good at spotting Changes..

Last resort

Thanks to Martin it switched from fish to inverts & 'lepas sp'.
As a last resort I tried agreeing with the 1st ID & then unagreeing & it switched it to L. anatifera!
