Help ID -- Small antenna on Snail Shell

[jakery]

Here is one for you guys.

This snail has 3 of these little pairs of curved antenna coming off the shell in various locations.

They can retract, but I don't know what the creature is called ?

Please help ID

thx

I'll take a guess.
I have seen mini brittle stars hang out a few arms like that to catch debris floating by.

I do not think its star fish arms, but good guess.

The two antenna move in unison & they are mirrored shape.

I will try to get a better photo tonight.

One other thing I've seen that looks like that is a small barnacle.
