Polygyridae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea. [2]The Polygyridae make up a significant proportion of the land snail fauna of eastern North America, and are also found in western North America, northern Central America, and are present on some Caribbean islands.
The structure of the radula of these snails (their "teeth") is unusual. Essentially, haplotrematids have fewer cusps than most snails, but they are considerably elongated, suitable for the predatory life they follow. Members of this family have been given the common name "lancetooth" snails, presumably based on this last anatomical characteristic.
The grove snail, brown-lipped snail or lemon snail (Cepaea nemoralis) is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc. [3] It is one of the most common large species of land snail in Europe, and has been introduced to North America. Subspecies. Cepaea nemoralis etrusca (Rossmässler, 1835) [4]
Neohelix albolabris is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Polygyridae. Alternate names for Neohelix albolabris are Helix albolabris and Triodopsis albolabris. It is the first land snail to be named by an American-born naturalist, Thomas Say in 1817.
Again, in some land snails, an unusual feature of the reproductive system of gastropods is the presence and utilization of love darts. In many marine gastropods other than the opisthobranchs, there are separate sexes (dioecious/gonochoric); most land gastropods, however, are hermaphrodites.
Orthalicidae (orthalicid land snails) are a family of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks are classified in the subfamily Orthalicoidea of the order Stylommatophora. [2] They are medium-sized to large snails, from about 3 cm (about 1.2 inches) to 9 cm (about 3.5 inches) in shell length
Megalobulimus paranaguensis is a species of air-breathing land snail, a terrestrial gastropod mollusk in the family Strophocheilidae. [2] They are native to South America and are known for being large and having a long lifespan. [3] The survival rate of males is 96.7% and similarly high for other members of the species.
