Not all land snails are edible since many are too small—not worthwhile to prepare and cook—and the palatability of the flesh varies among species. From the genus Helix: Helix lucorum, European snail; Helix pomatia, Roman snail or Burgundy escargot, is the most consumed species in France; Helix salomonica; From the family Achatinidae:
Edible molluscs are harvested from saltwater, freshwater, and the land, and include numerous members of the classes Gastropoda (snails), Bivalvia (clams, scallops, oysters etc.), Cephalopoda (octopus and squid), and Polyplacophora (chitons). Many species of molluscs are eaten worldwide, either cooked or raw.
Some snails like the Euglandina rosea, or rosy wolfsnail, are carnivorous and prey on other snails. [15] However, most land snails are herbivores or omnivores. [16] Among land snails, there is also a large variation in preference for specific food. For example, Cepaea nemoralis, or the grove snail, prefers dead plant material over fresh herbs ...
The first snails to hatch eat the shells of their eggs. This gives them calcium needed for their shells. They may then begin eating unhatched eggs. If the snail eggs are kept at the optimum temperature, 68 °F (20 °C) (for some varieties), and if none of the eggs lose moisture, most eggs will hatch within three days of each other.
The largest living species is the Giant African Snail or Ghana Tiger Snail (Achatina achatina; Family Achatinidae), which can measure up to 30 cm. [13] [14] The largest land snails of non-tropical Eurasia are endemic Caucasian snails Helix buchi and Helix goderdziana from the south-eastern Black Sea area in Georgia and Turkey; diameter of the ...
Chilinidae - small to medium-sized snails confined to temperate and cold South America. [9] About 15 species. [5] Latiidae - small limpet-like snails confined to New Zealand. [9] One [5] or three species. Acroloxidae - about 40 species. [5] Lymnaeidae - found worldwide, but are most numerous in temperate and northern regions. [9]
A molluscivore is a carnivorous animal that specialises in feeding on molluscs such as gastropods, bivalves, brachiopods and cephalopods.Known molluscivores include numerous predatory (and often cannibalistic) molluscs, (e.g. octopuses, murexes, decollate snails and oyster drills), arthropods such as crabs and firefly larvae, and vertebrates such as fish, birds and mammals.

The shells of most species of sea snails are spirally coiled. Some, though, have conical shells, and these are often referred to by the common name of limpets . In one unusual family ( Juliidae ), the shell of the snail has become two hinged plates closely resembling those of a bivalve ; this family is sometimes called the "bivalved gastropods".
