Beach geeking 2

Something on seaweed (open egg cases?)
and some bristleworms

Barnacle encrusted mussel shell

Young barnacles, old barnacles and periwinkles

A limpet shell pool.

The beasties above and below are Lipura maritima. Description in Collins Pocket Guide to the Sea Shore, Barrett and Yonge, 1958: "perhaps 1/8inch long; usually on surface film of rock pools especially where these are small and very sheltered. Upper half of shore, often in groups; also moving on rocks and weeds." I think pools in limpet and mussel shells count as small!
