Download A synoposis of the marine prosobranch gastropod and bivalve mollusks in Alaskan waters
Prosobranch, any snail of the subclass Prosobranchia, class bowvalleychorus.com of these roughly 20, snail species are marine; a few live on land or in fresh water. Many prosobranchs breathe by means of gills, which are located in the mantle cavity in front of the heart; some have a special respiratory structure on the mantle or, in land species, a simple pulmonary cavity.
Prosobranchia was a large taxonomic subclass of sea snails, land snails and freshwater snails. A synoposis of the marine prosobranch gastropod and bivalve mollusks in Alaskan waters book This taxon of gastropods dates back to the s.
It has however been proven to be polyphyletic (consisting of more than one lineage of descent). Generally speaking in biology taxonomy is required to reflect phylogeny, in other words the classification of a group must reflect its evolutionary descent.

These gastropods, sometimes called sea slugs and sea hares, breathe either through gills, which are located behind the heart, or through the body surface. The shell and mantle cavity are reduced or lacking in most species. In a special way, the different kinds of marine gastropods, assembled in the "Prosobranchia" group in outdated literature, have to be put against the opisthobranch gastropods (Opisthobranchia) and the lung snails (Pulmonata), which are found on land and in fresh water.

Oct 26, · The impact of predator-prey interactions on the evolution of many marine invertebrates is poorly understood. Since barriers to genetic exchange are less obvious in the marine realm than in terrestrial or freshwater systems, non-allopatric divergence may play a fundamental role in the generation of biodiversity.
