Second shell on my turbo shell... parasite?

[Skarletskunk30]

On my turbo grazer there is somthing that looks like a second little bump of a shell. I was looking really close and it opened up and has antennas and is long and black. It looked like it was cleaning like a snail but idk what it is. It looks like a long black tube when it is stretching out. Please help! What is it?!

Looks like a slipper limpet. They like to hitch rides on snails. Good hitchhiker if it is

I'm still only a lil under one year into saltwater and I saw it and was like it looks like an alien mini leach lol
