I don't think anyone with more experience than I has answered this yet,
so...
The large protoconch of most volutes is a clue that they do not have a
veliger stage but crawl directly from the egg, thereby limiting the range.
Didn't I read something some time back about a Cymbium species that was
observed disgorging live young direct from the mother (I think she was
brooding the eggs). If so, I'd like the reference to review it.
