hitchhiker limpet? ID?

[elvn]

Hi , I was wondering if anyone knows what this hitchhiker is. I found it piggy-back on one of my mexican turbo snail's shells. At first I thought it was part of the shell until I saw it moving. I'd like to know what it is so I can determine if its safe to put back into my setup.

The underside picture came out blurry, sorry.

Impossible to give you a Family, Genus and Species ID with that picture. It looks to be a member of the Class: Polyplacophora (Chiton). Most are harmless herbivores but some are omnivores feeding on other chitons, tunicates, sponges, small crustaceans and worms.

Looks like an abalone to me, although better pics would help.
