Description
The Sand-dusted Cone is a species of predatory sea snail, characterized by its classic conical shell shape. The shell is typically cream to off-white, densely covered with fine dark brown to black dots that give it a granular or 'sand-dusted' appearance. These dots often coalesce into irregular axial bands or blotches. The spire is low, and the aperture is white. In the image, the living snail is partially buried in a sandy substrate, with its reddish-pink siphon extended from the anterior end of the shell.
