DescriptionThe broadly webbed shell of this beautiful murex snail functions to stabilize the orientation of the animal in loose bottom sediments and also protects its soft foot (specialized body part used for locomotion) against attack by fish and other predators. This species is also protected by a brown corneous or horn-like operculum which acts like a plug filling the aperture or opening of the shell with the soft body pulled safely inside. This species is common from Japan to the Philippines and lives in deep water. It reaches 15 to 20 cm in length. Like other murex species, Siratus alabaster is a rapacious or ravenous carnivore, preying on other molluscs, especially clams, by drilling a hole through the shell of its victim and feeding on the soft tissues inside.
