Peronia
''Peronia'' is a genus of air-breathing sea slugs, a shell-less marine pulmonate gastropod mollusks in the family Onchidiidae. These slugs differ from other onchidiid slugs in having branched "gills" on their dorsal side, although these can be retracted. More than two dozen species of ''Peronia'' have been described from the Indo-West Pacific, but a recent revision of the genus determined that 21 of these names are synonyms. Nine species of ''Peronia'' are recognized, most of which can differentiated only by examining their internal anatomy or with DNA sequencing. Species The following species are species currently recognized within the genus ''Peronia'': * ''Peronia anomala'' Labbé, 1934 * ''Peronia griffithsi'' Dayrat & Goulding, 2017 *''Peronia madagascariensis'' (Labbé, 1934) * ''Peronia okinawensis'' Dayrat & Goulding, 2020 * ''Peronia peronii'' (Cuvier, 1804) *''Peronia platei ''Peronia platei'' is a species of slug, a marine gastropod mollusk in the family Onchi ...

Peronia Platei
''Peronia platei'' is a species of slug, a marine gastropod mollusk in the family Onchidiidae, one of the families of sea slugs. Nine species of ''Peronia'' are recognized; the way to tell them apart is by DNA sequencing by mitochondrial and nuclear sequence or checking their internal anatomy. This species has hermaphroditic parts in the posterior regions of the deferent duct and straight oviduct. The male part is the muscular sac of the accessory penial gland in the anterior area. It is distributed across the entire tropical and subtropical Indo-West Pacific, from South Africa to Hawaii. Classification Intertidal sea slugs are gastropods belonging to the subclass Heterobranchia and the family Onchiididae. They share many characteristics of shell-less marine mollusks, including dorsal gills that are visible when relaxed and retracted when crawling during low tide. Distribution and habitat This species has a cosmopolitan distribution across the entire tropical and subtropical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onchidiidae
Onchidiidae are a family of small, air-breathing sea (and land) slugs. They are shell-less marine (except for 2 species)preview pulmonate gastropod molluscs. Onchidiidae is the only family within the superfamily Onchidioidea. These animals are quite unusual in that they are emphatically not opisthobranchs with gills, as are almost all of the sea slugs. Instead these creatures are pulmonates. They are more closely related to air-breathing land and freshwater snails and slugs than they are to most other sea snails and sea slugs. This family has no subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). 143 species names were created within the Onchidiidae, but until recently few species could be identified. In the late 1920s Hoffmann revised the family (based on the descriptions), and classified the described species into genera. Labbé later continued the revision and named many new genera in his classification of onchidiid slugs. Labbé also made ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peronia Anomala
''Peronia anomala'' is a species of air-breathing sea slug, a shell-less marine pulmonate gastropod mollusk in the family Onchidiidae. It is the most recently discovered species of the genus of Peronia, found in the Red Sea in 1934. Description The sea-slug has a small pleural tooth 54μ wide, described by Labbé as "a bit like P. verruclata". Their size ranged from 10 to 5 mm in length and they have a very contacted body, almost globular. They also have thin integuments and a slightly pigmented pleural cavity The pleural cavity, pleural space, or interpleural space is the potential space between the pleurae of the pleural sac that surrounds each lung. A small amount of serous pleural fluid is maintained in the pleural cavity to enable lubrication b .... Distribution P. anomala lives in a marine biome sea habitat.

Sea Slug
Sea slug is a common name for some marine invertebrates with varying levels of resemblance to terrestrial slugs. Most creatures known as sea slugs are gastropods, i.e. they are sea snails (marine gastropod mollusks) that over evolutionary time have either completely lost their shells, or have seemingly lost their shells due to having a greatly reduced or internal shell. The name "sea slug" is most often applied to nudibranchs, as well as to a paraphyletic set of other marine gastropods without obvious shells. Sea slugs have an enormous variation in body shape, color, and size. Most are partially translucent. The often bright colors of reef-dwelling species implies that these animals are under constant threat of predators, but the color can serve as a warning to other animals of the sea slug's toxic stinging cells ( nematocysts) or offensive taste. Like all gastropods, they have small, razor-sharp teeth, called radulas. Most sea slugs have a pair of rhinophores—sens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thalia (plant)
''Thalia'' is a genus of six currently recognized species found in aquatic or marshy habitats, ranging in Africa from Senegal to Sudan to Zimbabwe, and in the Americas from Illinois to Argentina. Alligator-flag is a common name for plants in this genus. The generic name is in honor of Johannes Thal (1542–1583), a German doctor who wrote a Flora of the Harz Mountains. Cultivation Semihardy in cultivation, it needs protection against frosts. It can be propagated by seed or division of the rootstock in the spring. Species Species: * ''Thalia dealbata'' Fraser - southeastern United States * ''Thalia densibracteata'' Petersen - Brazil * ''Thalia geniculata'' L. - Africa, Florida, Louisiana, tropical Americas * ''Thalia multiflora'' Horkel ex Körn. - Argentina, Brazil, Uruguay * ''Thalia pavonii'' Körn. - Ecuador * ''Thalia petersiana Thalia, Thalía, Thaleia or Thalian may refer to: People * Thalia (given name), including a list of people with the name * ...

Systellommatophora
The Systellommatophora (synonym Gymnomorpha) is a clade of primitive, air-breathing slugs, according to the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005). They are marine and terrestrial pulmonate gastropods within the Heterobranchia. There are two superfamilies in this clade. Slugs in the superfamily Onchidioidea are primarily marine (except for five land-dwelling or freshwater species), whereas slugs in the superfamily Veronicelloidea are primarily terrestrial. Anatomy No species in this clade have shells as adults. These slugs are distinguished by the location of the anus at the rear of the body. Although neither superfamily bears shells as adults, the Onchidioidea do possess a vestigial, non-mineralized shell sac and possess a larval shell. It is not known whether or not the veronicellids bear a larval shell. Taxonomy According to the previous taxonomy of the Gastropoda (Ponder & Lindberg, 1997) Systellommatophora was considered to be a suborder or an ord ...

Panpulmonata
Panpulmonata is a taxonomic clade of snails and slugs in the clade Heterobranchia within the clade Euthyneura. Panpulmonata was established as a new taxon by Jörger et al. in October 2010. The older name "Pulmonata" referred to a group of gastropods which were considered to be "air-breathers". This meaning certainly does not apply to the panpulmonate groups Acochlidia, Sacoglossa and Pyramidelloidea, and also was inaccurate when applied to some of the more traditional pulmonate taxa such as Siphonarioidea or Hygrophila, most members of which lack permanently air-filled lungs. However, the term Panpulmonata was chosen by Jörger et al. (2010) to provide some continuity in the terminology. Panpulmonata consists of following taxa: * Siphonarioidea * Sacoglossa * Glacidorboidea * Amphiboloidea * Pyramidelloidea * Hygrophila * Acochlidiacea (mentioned as Acochlidia) * Eupulmonata: Stylommatophora, Systellommatophora, Ellobioidea, Otinoidea, Trimusculoidea.

Euthyneura
Euthyneura is a taxonomic infraclass of snails and slugs, which includes species exclusively from marine, aquatic and terrestrial gastropod mollusks in the clade Heterobranchia. Euthyneura are characterised by several autapomorphies, but are named for euthyneury. They are considered to be the most successful and diverse group of Gastropoda. Within this taxon, the Gastropoda have reached their peak in species richness and ecological diversity. This obvious evolutionary success can probably be attributed to several factors. Marine Opisthobranchia, e.g., have evolved several clades specialised on less used food resources such as sponges or cnidarians. A key innovation in the evolution of Pulmonata was the colonization of freshwater and terrestrial habitats.Klussmann-Kolb A., Dinapoli A., Kuhn K., Streit B. & Albrecht C. (2008).
