They fed the animals with small bivalves in the laboratory, and found that they drilled holes in the bivalves, apparently by chemical dissolution.
The size of the holes was smaller than the mollusc’s proboscis, so they proposed that the mollusc introduces a toxic secretion through it to kill or relax the prey.

Shell low end A totally particular development of the varices is found in the Muricidae, the Ranellidae (formerly Cymatiidae), and the Bursidae, for example, while in the Epitoniidae they maintain a characteristic lamellar structure and are present in relatively high numbers.
Murex, Siratus, Pterynotus and Ceratostoma, the conformation of the last varix contributes to protecting the mollusc from attacks from predators, since it is shielded by a true barrier of spines, as in the Murex, or by a uniform septum, thin but relatively solid.
And precisely in the Strombidae - and probably not by chance - almost all of the larger and more massive species, such as those of the subgenus Tricornis, have an aperture which is extremely developed and falring, forming a sort of large "wing", as can be seen in Strombus gigas, goliath and latissimus.
