it look like a Nassarius Snail

Nassarius Snail is a wonderful reef tank scavenger. These snails have a trunk-like tube they extend from their curved shells in order to hunt down food. The Nassarius will often times bury itself into the sand bed and wait until it senses food in its vicinity. They are good at keeping the top layer of the sand bed stirred up without damaging microfauna. They are great at removing detritus, uneaten food, and waste from the bottom of aquariums.Snails belong to a Class known as Gastropods, which make up the largest class of Mollusks. Snails grow by increasing their swirling body while producing a protective shell. This shell protects their soft body from predators. They will use a pad, or foot, that extends from their shell which allows them to drag their shell along. As they drag their shell often times their mouth and eyes can be seen coming out from the opening of the shell. When frightened or sleeping this opening can be protected by an operculum, which is a hard protective cover that acts like a door to the shell. Snail identification
