Micropilina is a genus of monoplacophoran molluscs. They are very small, mostly deepwater animals which have a superficially limpet-like shell.
In addition to a number of living, deep-sea species, this genus also includes a shallow water fossil from the middle Pleistocene of Italy - and this is the only fossil representative of this lineage subsequent to the Devonian period.[1]
All currently known Micropilina species are less than 1.5 mm in length. Except for Micropilina minuta, they are all found in the Southern Hemisphere.[2]
