Euglandina rosea, the rosy wolfsnail or cannibal snail, is a species of medium-sized to large predatory air-breathing land snail, a carnivorous terrestrial pulmonate gastropod mollusk in the family Spiraxidae. [1] This species is a fast and voracious predator, hunting and eating other snails and slugs. [2]
There are 34 freshwater gastropod taxa on this list. The only marine endangered gastropod is Haliotis sorenseni. The only overseas endangered land snail is Papustyla pulcherrima. Altogether 36 gastropod species are federally listed as of 2 October 2009. [2]
Again, in some land snails, an unusual feature of the reproductive system of gastropods is the presence and utilization of love darts. [citation needed] In many marine gastropods other than the opisthobranchs, there are separate sexes (dioecious/gonochoric); most land gastropods, however, are hermaphrodites. [citation needed]
Camaenidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea, the typical snails and their allies. This is one of the most diverse families in the clade Stylommatophora. These snails occur in a wide variety of habitats in the tropics of Eastern Asia and Australasia. [2]
Vertigo modesta, common name the cross vertigo, is a species of small air-breathing land snail, a terrestrial pulmonate gastropod mollusk or micromollusk in the family Vertiginidae, the whorl snails. [1] Subspecies. Vertigo modesta castanea Pilsbry & Vanatta, 1900; Vertigo modesta concinnula Cockerell, 1897; Vertigo modesta modesta (Say, 1824)
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.
Cerion is a genus of small to medium-sized tropical air-breathing land snails, terrestrial pulmonate gastropods in the family Cerionidae, noted for its extreme morphological diversity. The genus is endemic to the Caribbean region. [4] [5] Cerion has been a model organism in evolutionary biology.
Stylommatophora is the most diverse group of land snails and slugs. Pallial cavity forms a spacious, air-filled lung. Anus is located on the right side close to the pneumostome. Operculum is missing. Two pairs of tentacle are retractable and the posterior pair bears eyes on the tips. Radula typically has many small, quite uniform teeth per row.
