This genus was placed in the family Muricidae by Drivas & Jay, 1988[2] and by Richmond, 1997.[3]
Description
Drupella can be recognised by their extremely long, thin lateral teeth. The shells and radulae vary considerably even within species, complicating the taxonomy of the genus. The colour of the shell aperture varies from white to purple. Some species show sexual dimorphism in their radulae, with males having larger rachidian teeth than females.[4]
Diet
Snails of this genus are specialist predators of coral polyps.[4]
