The following classification summarizes the suprageneric taxonomy
Successions of erroneous taxonomic identifications in biodiversity studies are an undesirable but not rare phenomenon. Such cascades errors frequently involve taxa with few, polymorphic diagnostic characters, such as representatives the cuspidariid genus Cardiomya. Four species believed to live Brazilian waters: C. cleryana (d'Orbigny, 1842), ornatissima 1853), striata (Jeffreys, 1876) and perrostrata (Dall, 1881). Many reported occurrences these based on misidentifications, error cascade...
The family Omalogyridae comprises some of the smallest known marine snails. Like all micromolluscs, they have been historically neglected and are underrepresented in faunistic surveys. Based on a few focused studies family, 15 valid omalogyrid species were previously recognised Indian Pacific Oceans. To these, we add 3 new based morphological analysis material dry collection Natural History Museum Los Angeles County, applying light scanning electron microscopies. species, Ammonicera mcleani,...
The ligamental apparatus of Thracia comprises external and internal resilient components, as well a calcified ossicle termed the lithodesma. All these elements have hitherto been considered portions single unit their allometry functional morphology interpreted such. However, analyses fine structure hinge growth series phaseolina using conventional light, confocal scanning electron microscopy revealed that, instead, components comprise distinct, independent layers fibrous ligament, each...

Faunistic surveys are fundamental in the conservation of land mollusks, particularly as a means achieving accurate estimates species richness and levels extinction endangered taxa. The family Endodontidae comprises one most diverse groups indigenous snails Pacific Islands. Due to anthropogenic degradation their habitats, members now extinct or severely endangered. In Rurutu, French Polynesia, 11 were previously described (10 endemics), but only 1 is known have been extant during first half...
The functional morphology of the Thraciidae is poorly understood. Although some morphological aspects several members have been described, only Trigonothracia jinxingae from Chinese waters known in detail. Thracia meridionalis representative family Antarctic waters, and common Admiralty Bay, King George Island, where it inhabits muddy sediments. shares many features with Tr. that are typical most Anomalodesmata, i.e. a secondary ‘ligament’ thickened periostracum, extensively fused mantle...
Abstract The mantle margins of several anomalodesmatans bear multicellular arenophilic glands, the mucoid secretions which attach sand grains and other foreign particles to outer surface periostracum. These glands have been recorded for many anomalodesmatan families are used as a key morphological character in recent attempts unravel evolutionary relationships within Anomalodesmata. occur Laternula elliptica , L. truncata boschasina marilina discharging from top muscular papillae at distal...
‘Umbonal sculptures’ of freshwater mussels (Unionida), which ornament the early ontogenetic shell, have long been used for species identification. Specificity these sculptures to higher taxonomic levels and their value phylogenetic reconstruction are still under considerable scientific debate. In particular, distribution beak sculpture morphotypes across unionoid phylogeny and, consequently, evolution this character remain poorly understood. Based on an examination 187 taxa, covering five...
The arenophilic system of anomalodesmatan clams comprises multicellular glands, muscular papillae, and radial lines adhesive secretion, which glue sand grains other extraneous particles to the external surface shell. presence morphology these organs have been established in an increasing number taxa, but glands were not previously known occur deep-sea, carnivorous family Cuspidariidae. Dissections, histological sections ultrastructural examination members cuspidariid genera Cuspidaria...
Arenophilic glands represent the only molluscan example of multicellular organs solely concerned with adhesion foreign particles to external surfaces an organism. The are exclusive bivalve clade omalodesmata, but do not occur in all component taxa, having been declared absent a number families, including Pholadomyidae. This paper records and describes for first time arenophilic apparatus Pholadomya candida G. B. Sowerby I, 1823, demonstrates that secretion from these is at times...
that the embryonic, larval, metamorphic, and postlarval (juvenile to adult) phases represent major developmental alternations in this sense.The term phase is herein restricted refer a certain period.Comparisons between trajectories of organisms require reference points marking onset offset phases.Traditionally, these boundaries have been defined on basis morphologically recognizable markers, such as appearance disappearance organs or, case molluscan shell development, changes structure,...
The family Endodontidae Pilsbry, 1895 comprised one of the most diverse groups indigenous land snails Pacific Islands. However, due to anthropogenic degradation their habitats and predation by or competition with introduced species, members are now extinct severely endangered. Based on limited sporadic collections, endodontid fauna raised coral island Makatea in western Tuamotu Archipelago was known consist four valid Mautodontha (Mautodontha) daedalea (Gould, 1846), Kleokyphus callimus...
Laternula elliptica (P. P. King, 1832) is the sole representative of anomalodesmatan family Laternulidae and largest bivalve in Antarctic Subantarctic. A keystone species regional benthic communities, it has reached model status, having been studied hundreds scientific works across many biological disciplines. In contrast, its anatomy remained poorly known, with prior published data limited to partial descriptions based on chemically preserved specimens. Based observations...
