Remarks.
It is a very common sublittoral species, mainly in shallow waters, along all European and North African coasts from
Norway
to
Morocco
and throughout the Mediterranean, not present on the Macaronesian islands (
Oliver
et al
. 2019
). Very few eroded shells (
Fig. 21e
) have been found in samples obtained at the depth range of
150–345 m
, likely swept by the currents away from the coast.
