A new Antarctic heterobranch clade is sister to all other Cephalaspidea (Mollusca: Gastropoda)
Zoologica Scripta, 2016For a long time, Diaphanidae has been considered a basal family within Cephalaspidea, based on the presence of plesiomorphic morphological features within this taxon. Traditionally, the family contained the genera Bogasonia, Colobocephalus, Colpodaspis, Diaphana, Newnesia, Toledonia and Woodbridgea. Some phylogenetic analyses of several of these genera

Abstract In this work we report on a mating aggregation of the marine mangrove dweller gastropod Bakawan rotundata (A. Adams, 1850), observed in the Sewri mud flats near Mumbai in western India. From October 2018 the area has been surveyed monthly for its biodiversity composition.

Haminoeidae is the most diverse family of Cephalaspidea with 13 to 17 genera commonly recognised as valid and with 46 genera that historically have been moved back and forth between Haminoeidae and other families. Due to poor definition of most genera the family is plagued by extensive taxonomic confusion and its generic composition and internal ...

AbstractThe hermaphroditic marine snail species Haminella solitaria was formerly included in the genus Haminoea, but it was recently assigned to the genus Haminella. The copulatory apparatus in H. solitaria was investigated by light and transmission electron microscopy to obtain additional information about this apparatus in cephalaspidean gastropods ...

Navanax inermis are internally fertilizing, simultaneous hermaphrodites that normally mate in pairs. Copulations usually occur in bouts with active alternation of sexual roles and function. Over the study, individuals copulated equally often and for equal periods of time as each sex.

The colonization of foreign species into the Mediterranean Sea has increased in number and geographic coverage over the past decades. For instance, the marine mollusc Haminoea cyanomarginata has scattered across the Central and Eastern Mediterranean since its description in the Red Sea by Heller and Thompson in 1983.
