THing on snail

[brent6969]

i have some sorta of black thing on my turbo snail. It looks like its part of the snail but when i looked up at it close it had some sort of stringy thing that came out of it trying to grab food. Anyone know what this is.

not sure what it is, but I have a few of those critters on my rock. Almost like a tube worm but instead of all the fingers, it's got a single long tentacle coming out. I'd like to know what they are, too.

I do have a feather duster that has made his home on the back of one of my scarlett hermits though. That made me laugh when I saw it

Possibly an anemone crab or its Penis.
