Pulmonata or pulmonates is an informal group (previously an order, and before that, a subclass) of snails and slugs characterized by the ability to breathe air, by virtue of having a pallial lung instead of a gill, or gills. The group includes many land and freshwater families, and several marine families.
In gastropods in many ancient lineages, the gills are bipectinate, having an overall shape that is similar to a bird's feather, with narrow filaments projecting either side of a central stalk. Gastropods such as abalone and keyhole limpets have two gills, which is believed to be the arrangement in the earliest fossil gastropods. The water ...
Pneumopulmonata is a superorder of heterobranch pulmonate gastropods belonging to the subterclass Tectipleura. It was defined based on results of phylogenomic studies [1] [2] and named by Krug et al. (2022). The superorder unites all of Panpulmonata except for Sacoglossa.
This is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Bradybaenidae. This species is endemic to Japan, and exhibits exceptional geographical variation in its mitochondrial DNA. As Euhadra peliomphala matures sexually, it develops a "head-wart" between the optic tentacles. The development of the ...
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]
Courtship is a part of the behavior of mating gastropods with some pulmonate families of land snails creating and utilizing love darts, the throwing of which have been identified as a form of sexual selection. [25] The main aspects of the life cycle of gastropods include: Egg laying and the eggs of gastropods; The embryonic development of ...
Latia is a genus of very small, air-breathing freshwater snails or limpets, aquatic pulmonate gastropod molluscs in the superfamily Chilinoidea. [5] Latia is the only genus in the family Latiidae. Species in this genus are the only freshwater bioluminescent molluscs in the world. [6]
Gundlachia is a genus of minute freshwater snails or limpets, aquatic pulmonate gastropod mollusks in the family Planorbidae, the ram's horn snails and their allies. The generic name is in honor of Cuban naturalist Juan Gundlach (1810-1896).
