Ruh-roh, are you sure you included all the possible hash-tags, there? 😬
Btw, what kinds of little creatures might you be seeing on those rocky shores?
A quick search of your specific area suggested: acorn barnacles (Balanus improvisus), sea slaters (Ligia oceanica), gammarids (Gammarus sp.), blue mussels (Mytilus trossulus), periwinkles (Littorina sp.) and river nerite snails (Theodoxus fluviatilis).
I think I'd go in to a trance-state if I saw even a few of those!
