Abstract The superfamily Buccinoidea is distributed across the oceans of world from Arctic Ocean to Antarctic and intertidal abyssal depths. It encompasses 3351 recent species in 337 genera. latest taxonomic account recognized eight full families. For first time, monophyly relationships among families are tested with molecular data supplemented by anatomical radula data. Five genetic markers we...

The Neogastropoda include many familiar molluscs, such as cone snails (Conidae), purple dye snails (Muricidae), mud snails (Nassariidae), olive snails (Olividae), oyster drills (Muricidae), tulip shells (Fasciolariidae), and whelks (Buccinidae). Due to their amazing predatory specializations, neogastropods are often dominantmembers of the benthic community at the top of the food chain. In a daz...

Some generally accepted viewpoints on the phylogenetic relationships within the molluscan class Gastropoda are reassessed by comparing complete 18S rRNA sequences. Phylogenetic analyses were performed using the neighbor-joining and maximum parsimony methods. The previously suggested basal position of Archaeogastropoda, including Neritimorpha and Vetigastropoda, in the gastropod clade is confirm...
