Capulus subcompressus Pelseneer, 1903 (Gastropoda: Capulidae) is a small epibiont gastropod living at Terra Nova Bay (Ross Sea) down to 540 m on the calcareous tubes of its unique host, the serpulid Serpula narconensis Baird, 1865. This polychaete forms bush-like aggregates which host a rich microfauna of crustaceans, hydroids and molluscs. In contrast to all other capulids, C. subcompressus shows an evident oval shell aperture, which is due to an allometric growth that can be imputed to the… 
The limpet form in gastropods: evolution, distribution, and implications for the comparative study of history
A survey of fossil and living limpets indicates that the limpet form evolved independently in at least 54 lineages, with particularly frequent origins in early-diverging gastropod clades, as well as in Neritimorpha and Heterobranchia.
Substrate-dependent shell morphology in a deep-sea vetigastropod limpet
It is shown that the vetigastropod limpet Lepetodrilus nux from a deep-sea hot vent in the Okinawa Trough develop distinct shell forms when living on different substrate types, and provides further evidence that such plasticity is not phylogenetically constrained but is an intrinsic part of having a limpet-like shell.
A New Vent Limpet in the Genus Lepetodrilus (Gastropoda: Lepetodrilidae) From Southern Ocean Hydrothermal Vent Fields Showing High Phenotypic Plasticity
The recently discovered hydrothermal vent ecosystems in the Southern Ocean host a suite of vent-endemic species, including lepetodrilid limpets dominating in abundance, and genetic distinctness and pylogenetic position with congeners based on the mitochondrial COI gene is evaluated.
Developmental trade-offs in Southern Ocean mollusc kleptoparasitic species
The data showed that whilst larval planktotrophy is the predominant larval strategy of the Capulidae family worldwide, the vast majority of Antarctic species exhibit non-planktotrophic development, and the unique exception, Capulus subcompressus, showed high genetic connectivity between the Ross Sea and Weddell Sea-Antarctic Peninsula.
Kleptoparasitism is pervasive throughout the range of T. cancellata, occurring with equal frequency throughout the areas studied, and snail and worm densities are not significantly correlated at the larger scale of site (averaged over nearby sampling locations clustered around a city), but are correlated at a smaller local scale (within a sampling location).
Polynoid polychaetes living in the gut of irregular sea urchins: a first case of inquilinism in the Southern Ocean
This paper presents an inquilinistic association involving two Antarctic species, the polychaete Gorekia crassicirris and the irregular sea urchin Abatus nimrodi and the Schizasteridae found in the Ross Sea.
Antarctic associations: the parasitic relationship between the gastropod Bathycrinicola tumidula (Thiele, 1912) (Ptenoglossa: Eulimidae) and the comatulid Notocrinus virilis Mortensen, 1917 (Crinoidea: Notocrinidae) in the Ross Sea
The absence of suitable Bathycrinidae host in modern Antarctic benthic assemblages, as well as the long paleontological history of the genus Notocrinus in Antarctica, suggest a possible ‘host-switch’ phenomenon.

A special adaptation to planktonic life in larvae of the Cassoidea (=Tonnoidea) (Gastropoda)
It is demonstrated that cassoid larval conch characters are sufficient to prove the existence of a pallial appendage without anatomical confirmation and suggested that the adaptation of cassoid larvae to pelagic life is unique among gastropods representing an autapomorphic character of the superfamily.
