Sea-life ID's from North Wales

[agrumpycow]

Can anyone help with some ID's and confirmations for this selection from the beaches of North Wales. My knowledge of sea life is almost non existant and I'd like to learn

This plant was in a shallow rock pool


I think these are periwinkles but which one?


Limpets & anenome but, again, which ones?


I think these are mussels but which? Very small, about 1-1.5cm in length each


Finally, my husband calls these 'shark's purses' but can anyone give a more specific species?


Cheers in advance

4. Common Mussel (Mytillus edulis)
5. eggcase of a dogfish - not sure what species
