The most recent classification, by Sirenko (2006),[35] is based not only on shell morphology, as usual, but also other important features, including aesthetes, girdle, radula, gills, glands, egg hull projections, and spermatozoids. B. I. Sirenko's 5 research works with 1 citations and 1 reads, including: Restoration of the genus Squamophora (Mollusca: Polyplacophora: Loricidae) Butterfly Chiton 8. [34], Based on this and co-occurring fossils, one plausible hypothesis for the origin of polyplacophora has that they formed when an aberrant monoplacophoran was born with multiple centres of calcification, rather than the usual one.
