Elemental composition and material properties of radular teeth in the heterobranch snail Gastropteron rubrum (Mollusca, Gastropoda, Cephalaspidea) foraging on hard organisms [PDF]
Ecology and Evolution, 2023 The molluscan feeding structure is the radula, a chitinous membrane with teeth, which are highly adapted to the food and the substrate to which the food is attached. In Polyplacophora and Patellogastropoda, the handling of hard ingesta can be facilitated

The complete mitochondrial genome of Haloa japonica (Pilsbry, 1895) (Cephalaspidea, Haminoeidae) [PDF]
Mitochondrial DNA. Part B. Resources, 2020 Haloa japonica is a bubble snail species in the family Haminoeidae. In the present study, the complete mitochondrial genome of H. japonica was decoded and analyzed. With the size of 13,797 bp, the mitogenome of H. japonica is the shortest among all known

TWO NEW SPECIES OF GASTROPTERIDAE FROM GUAM, MARIANAS ISLANDS (OPISTHOBRANCHIA : CEPHALASPIDEA) [PDF]
Publications of the Seto Marine Biological Laboratory, 1973 In 1964 Tokioka and Baba established the genus Sagaminopteron to accommodate one species, S. ornatum Tokioka and Baba, 1964. According to Tokioka and Baba Sagaminopteron differs from the Gastropteron in that the former has a radular formula of 9-12.1.0.1.

Use of axonal projection patterns for the homologisation of cerebral nerves in Opisthobranchia, Mollusca and Gastropoda. [PDF]
Front Zool, 2013 Introduction: Gastropoda are guided by several sensory organs in the head region, referred to as cephalic sensory organs (CSOs). These CSOs are innervated by distinct nerves.

Integrative Analysis of Retusa pertenuis (Heterobranchia: Cephalaspidea) from Arctic and Russian Far East Seas with Discussion of Its Morphology, Validity and Population Structure [PDF]
Diversity, 2023 Retusa pertenuis is still formally considered a junior subjective synonym of Retusa obtusa, despite previous data indicating R. pertenuis and R. obtusa differ significantly in copulatory system morphology. In this paper, we study the species identity and
