Olivier,

In 2008 I spent 5-6 months in New Zealand.  Most/all of our shell collecting
was intertidal.  I collected Zeatrophon ambiguus from a number of locations
on the North and the South islands.  In each location the shape and
sculpture were similar, but were quite variable between locations.  Here is
a link that shows this variability,

Thank you Roland. I imagined ambiguus much more variable.
I suppose these little animals feed on oysters?
