What snail is this

[rbell219]

I just moved all my saltwater fish to the new tank and found a snail still alive. I bought a few Turbo snails a while back to do some clean up. I new my trigger would get them eventually...and he did...I thought. I saw him eat two and assumed all three had met their maker.

SO...today when I was emptying the tank I found number 3 who I always suspected was not a turbo. His shell is different and when he retreats in the shell, what is exposed in the opening is hard like the rest of the shell. So I guess the trigger can't, or hasn't figured out how to get through this.

I know the description is lacking, but anyone have any thoughts on what type it is? I'll try to get a picture.

all snails have the cover over the opening. or at least.... all traditional looking snails. so all that tells us is that it is not a turbo. haha

At least that narrows it down. I'll try to get a picture...it's never visible during the day--always hiding somewhere.
