Predatory Zoanthid snail? Not a Sundial

[theplatypus]

I found a few of these little guys among some of my disappearing Zoas. Any ideas as to what they are? At the most they're 1/4" long. Sorry about the quality tiny specimen and no photo skills.

Looks like some kind of nassarius snail. They arnt a zoa preditor, but eat dead and decaying stuff. Does it have a "antenna" that comes out from the front? And does it burry its self in the sand?

Could be that the zoas are dying for some reason and the snails are just there to clean up. But...you never know.

No sand to bury into and I've only found them in Zoanthid colonies/frags.

Any other ideas?

How large are they??? I had some that looked like that... I had collected them in FL... Maybe an inch long... I'm not sure they were predatory toward zoas, but they were definately predatory toward other snails... They ate a few of my nassarius and ceriths...

They're only 1/4" or less(roughly 6mm). As it stands I've only found them on/between Zoanthid polyps or under the plugs/rocks that the Zoanthids are mounted on. They are a hitchhiker.
