The results imply that crown-group molluscan synapomorphies include serial repetition, the presence of a foot, a mineralized scleritome and a creeping rather than worm-like mode of life.
The Continuing Debate on Deep Molluscan Phylogeny: Evidence for Serialia (Mollusca, Monoplacophora + Polyplacophora)
A new molecular clock indicates that molluscs had a terminal Precambrian origin with rapid divergence of all eight extant classes in the Cambrian, and the recovery of Serialia as a derived, Late Cambrian clade is potentially in line with the stratigraphic chronology of morphologically heterogeneous early mollusc fossils.
A tale of two chitons: is habitat specialisation linked to distinct associated bacterial communities?

Investigation of the feeding strategies of two species, Leptochiton boucheti and Nierstraszella lineata, recovered on sunken wood sampled in the western Pacific suggests that the distinct associations with bacterial partners are linked to niche specialisations of the two species.

The results provide experimental evidence that anthropogenic noise has a marked effect on the behavior of species that are not reliant on acoustic communication, and interference in one sensory channel, in this case the acoustic one, affects signaling in other sensory channels.

Multigene analysis of standard nuclear and mitochondrial markers demonstrates that the topology of the order Chitonida is divided into four clades, which have also been recovered in previous studies: Mopalioidea is sister to Cryptoplacoidea, forming a clade Acanthochitonina.

Larval Transport Modeling of Deep-Sea Invertebrates Can Aid the Search for Undiscovered Populations
A new method that is broadly applicable to studies of the dispersal of deep-sea organisms, using non-feeding, non-swimming larvae of polyplacophoran molluscs (chitons) is presented.
A chiton without a foot
Phthipodochiton thraivensis presents an apparent mosaic of aplacophoran and polyplacphoran features and as such will inform the understanding of the relationship between these groups of extant molluscs.
