Thank you it is a stomatella, it must have come with a mushroom garden I bought thanks again.Not the best angle for IDing but looks like a large species of Stomatella - beneficial hitchhiker. Image search on the name and see if it looks like what you've got. Usually they are pretty small but I've seen the odd one up to an inch / couple cm. They do have a shell but it's small and up near the head, often largely covered in tissue so it's hard to see; they can't retract into it. Don't poke at it if you can avoid it, as Stomatella will sometimes drop the back part of their foot if spooked kind of like lizards dropping their tail. Some fish also eat them.
