What is this creature?

Can anyone id this please. The grey part on the left side is sucking onto the rock. The top is a shell. The right side has 2 antennae. It doesn’t swim or walk. It just sucks on to the rock to move.

Hard to tell on the pic but my guess is a stomatella based on the description

The photo is too blurry to tell. Can you post a better one?

The green on the right is the shell and head. The grey blob on the left seems to stay sucked to the rock.

Some sort of gastropod

Looks like it's probably a stomatella snail (as mentioned above) with algae on the shell.
