The Families Veneridae, Trochidae, Akeridae and Acteonidae (Mollusca), in the Romualdo Formation: Paleoecological and Paleobiogeographic Aspects in the Lower Cretaceous of the Araripe Basin, NE of Brazil [PDF]
Anuario Do Instituto De Geociencias, 2018 Fossil mollusks in the Araripe Sedimentary Basin have been reported since the 1960s, with bivalves present in the Crato and Romualdo formations and gastropods restricted to the latter. The identification and description of those mollusks have assisted in the paleoenvironmental reconstruction of the Romualdo Formation (Aptian-Albian) and in the ...

A new species of Acteon (Opisthobranchia: Acteonidae) from Northeast Brazil [PDF]
Zoologia, 2011 A new species of Acteon Montfort 1810, Acteon mirim sp. nov., from Canopus Bank, state of Ceará, Brazil is described based on shell morphology. The new species is compared with other species of the genus reported from Brazil. It differs from other Brazilian species in having a whitish color with dark orange-brown spiral bands and a shell surface ...

Ringiculid bubble snails recovered as the sister group to sea slugs (Nudipleura). [PDF]
Sci Rep, 2016 Euthyneuran gastropods represent one of the most diverse lineages in Mollusca (with over 30,000 species), play significant ecological roles in aquatic and terrestrial environments and affect many aspects of human life. However, our understanding of their

From sea to land and beyond--new insights into the evolution of euthyneuran Gastropoda (Mollusca). [PDF]
BMC Evol Biol, 2008 Background The Euthyneura are considered to be the most successful and diverse group of Gastropoda. Phylogenetically, they are riven with controversy.

Opisthobranchia (Mollusca, Gastropoda) - more than just slimy slugs. Shell reduction and its implications on defence and foraging. [PDF]
Front Zool, 2005 BACKGROUND: In general shell-less slugs are considered to be slimy animals with a rather dull appearance and a pest to garden plants. But marine slugs usually are beautifully coloured animals belonging to the less-known Opisthobranchia.

On the origin of Acochlidia and other enigmatic euthyneuran gastropods, with implications for the systematics of Heterobranchia. [PDF]
BMC Evol Biol, 2010 Background A robust phylogenetic hypothesis of euthyneuran gastropods, as a basis to reconstructing their evolutionary history, is still hindered by several groups of aberrant, more or less worm-like slugs with unclear phylogenetic relationships.

Unusual conservation of mitochondrial gene order in Crassostrea oysters: evidence for recent speciation in Asia. [PDF]
BMC Evol Biol, 2010 Background Oysters are morphologically plastic and hence difficult subjects for taxonomic and evolutionary studies. It is long been suspected, based on the extraordinary species diversity observed, that Asia Pacific is the epicenter of oyster speciation.
