Diameter is 2.1 cm. Underside of a snail climbing a blade of grass, showing the muscular foot and the pneumostome or respiratory pore on the animal's right side. Land snails move by gliding along on their muscular foot, which is lubricated with mucus and covered with epithelial cilia. [9]
A snail is a shelled gastropod. The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name snail is also used for most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract
Physa fontinalis, common name the common bladder snail, is a species of air-breathing freshwater snail, an aquatic gastropod mollusc in the family Physidae. The shells of species in the genus Physa are left-handed or sinistral .

[2] It shares the common name "giant African snail" with other species of snails such as Achatina achatina and Archachatina marginata. This snail species has been ...
Lymnaea stagnalis, better known as the great pond snail, is a species of large air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Lymnaeidae. The great pond snail is a model organism to study parasitology, neurology, embryonal development and genetic regulation.
The snail feeds on a variety of plants, including economically important crops such as bananas, lettuce, peanuts, and peas. [5] There are also possible public health ramifications of the spread of the snail as an invasive species: it is a carrier of the parasitic rat lungworm, which causes angiostrongyliasis, which in turn is the most common cause of the eosinophilic meningitis or eosinophilic ...
Each snail lays up to 1200 eggs per year. Achatina achatina is an important source of animal protein for West African forest-dwelling ethnic groups, and there is potential for commercial farming. [8] This species' substantial size and potential for rapid population growth can make the snail a serious pest when introduced to non-native ecosystems.
