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.
