Hi all, I’ve had a look through and not seeing much like these. The first one I thought maybe Vermetid Snail but can’t seem to see it on the rock. The white bit is also under the mushroom.

the second pic is next to the Mussel, it’s kind of pinkish in colour. You can see my BTA is looking quite tired above it.
