Oxygyrus inflatus B... Benson, W. H. (1835). Account of Oxygyrus a new genus of pelagian shells allied to the genus Atlanta of Lesueur, with a note on some other pelagian shells lately taken on board of the ship Malcolm.
However, the relationship between Oxygyrus and B. minuta remains enigmatic [ 22 ], and here we consider B. minuta to belong within the family Atlantidae, having a shell morphology very similar to the extant genus Oxygyrus [ 22 ]. Indeed, the World Register of Marine Species places the genus Bellerophina within the Family Atlantidae.
The family contains three genera ( Atlanta, Protatlanta and Oxygyrus) and is characterized by dextrally-coiled, aragonitic shells into which the soft body can fully retract, sealed by a chitinous operculum that is attached to the foot (Fig. 1 A, C).
Introduction Along with Atlanta peronii, Oxygyrus inflatusattains the largest shell size (diameter to 10 mm) in the family Atlantidae. The larval shell is calcareous and displays a distinctive pattern of evenly-spaced, zigzag-shaped spiral ridges oriented in the axis of shell growth and covering the shell surface.
