Mollusks-Gastropods

Gastropods represent the largest class of mollusks and are comprised of marine, freshwater and terrestrial snails and slugs. In marine systems, this includes: periwinkles, top-shells, whelks, limpets, and nudibranchs. They are abundant in marine ecosystems and are found in a variety of habitats from the intertidal to the deep sea. They exhibit a variety of body forms with some individuals being shelled (e.g. periwinkles and limpets) and others having reduced internal shells or no shell at all during their adult stage (e.g. nudibranchs). Many of the Gastropods in NEMESIS have been introduced by hitchhiking on aquaculture imports and commercial ships. The impacts of exotic gastropods are varied, with many having no reported impact, but some species can reach extraordinary densities and may compete with native species or alter natural food webs.
