In part, it depends on the definition of carnivore-the difference
between
grazing on algae and grazing on sessile organisms like bryozoans,
sponges,
etc.  may not be enough to require a change of radula.  There also may
be
some generalists.  I think Ilyanassa prefers grazing on microalgae,
whereas
Nassarius is often a scavenger, but I don't recall full details.
