The ability to feed on suspended and dissolved organic nutrients may have been retained in predatory gastropods during evolution. The carnivorous muricid neogastropod Thais clavigera feeds on prey by boring through their shells, followed by extracellular digestion and suction of the nutrient-rich fluid of the prey's body tissues.1. Helix pomatia. Also know as the Roman snail or Burgundy snail, this common garden snail is widely distributed in Europe. This type of garden snail can reach roughly 4 cm in height, and vary in brown tones.The Helix pomatia is a herbivore and feeds on pieces of fruit, leaves, sap and flowers.Many carnivorous gastropods are limited to whatever prey can be chased down at, well, a snail's pace, but the Conidae have developed a sophisticated technique for ensnaring even far speedier fish and crustacea.

Note that because few carnivorous gastropods prey exclusively on other gas-tropods (e.g. Taylor & Taylor 1977), we are not dealing with predator/prey ratios as analyzed in community food webs and subwebs.Carnivorous gastropods prey on economic bivalves, such as clams and oysters, causing heavy economic losses (Hu et al., 2016). For example, the invasive species R. venosa is an important cause of the dramatic decline in the abundance of bivalve species in the Black Sea ( Snigirov et al., 2013 ). ….
