Many forams, resting nematodes, some polychaet tubes etc are coiled.
Coiling is not limited to Mollusca, though it is most apparent in
that phylum. And among molluscs, cephalopod, scaphopod,
monoplacophoran, rostroconch (extinct) and bivalve shells are coiled,
not only gastropods, though in some the coiling is reduced or
secondarily modified.
