Records of extant Monoplacophora are still scarce, often limited to single specimens or empty shells. Little is known about monoplacophoran diversity, distribution and biology. This study summarizes the present distributional knowledge of all Antarctic monoplacophorans, adding new records from the Eastern Weddell Sea. The record of Laevipilina antarctica from over 3,000 m depth extends its previously known bathymetrical range from 210 to 644 m down to abyssal depths. Special symbiosis with… 
How well do we know the Antarctic marine fauna? A preliminary study of macroecological and biogeographical patterns in Southern Ocean gastropod and bivalve molluscs
The low species richness of the Southern Ocean molluscan fauna compared with many tropical sites is confirmed, and is related principally to the absence of the large number of rare taxa that characterize some tropical assemblages.
Southern Ocean Deep Benthic Biodiversity
High biological variability in SO deepsea isopods has revealed high biological variability, which indicates patchiness rather than rarity, of most isopod taxa (Kaiser et al., 2007).
Deep-sea video technology tracks a monoplacophoran to the end of its trail (Mollusca, Tryblidia)
Originally known as fossils from the Cambrian to the Devonian, the finding of a living monoplacophoran mollusc in 1952 was one of the great zoological discoveries of the twentieth century. Now, over
The origins of molluscs
Aplacophoran morphology therefore does not represent the plesiomorphic condition for molluscs as a whole, and the interrelationships among the conchiferan mollsuscs are still a matter of contention and require further palaeontological and molecular phylogenetic scrutiny.
Biodiversity and distribution of marine gastropods (Mollusca) during pre- and post-monsoon seasons along the Goa coastline, India
The results of this study indicate that the coasts of Goa are known to be a haven for gastropod fauna and needs to be protected to promote the conservation of this vulnerable resource.
A review on deep molluscan phylogeny: old markers, integrative approaches, persistent problems
This work questions recent opinions that the molluscan origin, deep inner relationships, and early evolution have been largely resolved and discusses recent progress regarding multilocus marker analyses, particularly refining the neglected Serialia hypothesis with Monoplacophoras sister to Polyplacophora.
On Aculifera: a review of hypotheses in tribute to Christoffer Schander
Support for the monophyly of Aculifera and Aplacophora is found among modern studies, and the anatomical implications for such relationships are discussed, but analyses of target-gene approaches often contradict this clade.

Anatomy of Laevipilina antarctica, a Monoplacophoran Limpet (Mollusca) from Antarctic Waters
Corrections and clarifications of the neopilinid anatomy provide an improved database for discussion on monoplacophoran affinities and are regarded as a considerably modified and specialized early conchiferan branch.
Evidence for a clade composed of molluscs with serially repeated structures: Monoplacophorans are related to chitons
The first molecular data on monoplacophorans, analyzed together with the largest data set of molluscs ever assembled, clearly illustrate that monoplacs and chitons form a clade and may have important implications for metazoan evolution.
Bacterial symbionts in the epidermis of an Antarctic neopilinid limpet (Mollusca, Monoplacophora)
For the first time it has become possible to study a `living fossil' Laevipilina antarctica, a representative of the family Neopilinidae by means of transmission electron microscopy, leading to the discovery of a bacterial symbiosis in the epidermis of the mantle roof and of the head of the animal.
Spermatozoa and spermatogenesis in a monoplacophoran mollusc, Laevipilina antarctica: ultrastructure and comparison with other Mollusca
Ultrastructural features of spermatozoa and spermatogenesis are described for the first time in a monoplacophoran and compared with data for other conchiferan molluses. Spermatozoa of Laevipilina
Monoplacophora in the South Atlantic Ocean
Occurrence of Neopilina off the southeastern tip of South America may indicate rather widespread distribution of this abyssal group, under favorable conditions, throughout the seas of the world.

Laevipilina Cachuchensis, A New Neopilinid (Mollusca: Tryblidia) From Off North Spain
A new tryblidian species, Laevipilina cachuchensis, is described from a depth of 580– 600 m on ‘El Cachucho’ Bank (Asturias, north Spain), differing mainly in shell characters and details of radular morphology.
