Need an id on this snail

[Denisk]

Part of getting live rock is that even two years later, you may notice a critter you never purchased or saw.

can anyone ID this little guy?

Thanks all!

Could be a nassarius or a whelk. Hard to tell without the coloration of the shell but since it's on glass its more likely a whelk. I found two whelks on my ocean rock. Whelks eat clams and sometimes other snails.

Nassarius vs Whelk

Appears to be a whelk. Very cool. Thank you!
