3 Marine Creatures for ID

[jdoherty]

I took all of these photos in early March 2010 along the shore of Belfast Lough at low tide. The first was probably about 2-3 cms long. The second worm was also very small as can be seen from the size of the barnacle in the same pic. The last creature was like a blob of jelly but it appears to have some 'feelers' to the left of it's body. Might it be some sort of snail/slug? It was also about 2-3cms in length. IDs please.

Thanks, John.

Hi John,
not really my area, being nearly as far from east and west coasts as poss, but 2 looks like a bristle worm, lumbriconeris latreilli..............!

The last one may be a sea slug, possibly pleurobranchus membranaceus ......................or not!
Cheers

Qualifying this by saying I live a similar distance from the sea as Ken - could the first be a Nereis type rag-worm or similar? I think the third is, as Ken suggests, a sea-slug of some type and the third I don't have much of an idea - maybe another Nereis type??

Thanks everyone for your help. Has anyone got any more suggestions?

Thanks, John.

I would say for the second one - defo a RagWorm? The first....a small Black Lugworm perhaps Lastly the third....a Sea Slug Wizzo

im not sure if number 2 is a ragworm or not.The ragworm i find are very large (6 - 14 inch plus) at low tide,you do tend to find smaller types of worms nearer the high tide mark,which this looks like.

Going for another go at this one,
1) Family Phyllodocidae, Paddle worm.
2) Family Syllidae, Kefersteinia currata.
3) Common grey sea slug,Aeolidia papillosa
