The digestive system of gastropods has evolved to suit almost every kind of diet and feeding behavior. Gastropods ( snails and slugs ) as the largest taxonomic class of the mollusca are very diverse: the group includes carnivores , herbivores , scavengers , filter feeders , and even parasites .

Gastropods have the greatest numbers of named mollusk species. However, estimates of the total number of gastropod species vary widely, depending on cited sources. The number of gastropod species can be ascertained from estimates of the number of described species of Mollusca with accepted names: about 85,000 (minimum 50,000, maximum 120,000). [9]
The excretory system of gastropods removes nitrogenous waste and maintains the internal water balance of these creatures, commonly referred to as snails and slugs. The primary organ of excretion is a nephridium. Drawing of excretory system of Lymnaea meridensis; renal tube and ureter in renal region extending between pericardium and mantle collar

The radula (US: / ˈ r æ dʒ ʊ l ə /; pl.: radulae or radulas) [1] is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue. [2] It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus.
The hepatopancreas, digestive gland or midgut gland is an organ of the digestive tract of arthropods and molluscs. It provides the functions which in mammals are provided separately by the liver and pancreas , including the production of digestive enzymes , and absorption of digested food.
