Tandonia is a genus of air-breathing, keeled, land slugs. These are shell-less terrestrial gastropod mollusks in the family Milacidae.
The distribution of the genus Tandonia includes Europe to North Africa and Asia Minor. [2] The largest number of species are in the southern Alps. [2]
The slug's body is elongate, up to 100 mm in length, and usually with almost parallel sides. The posterior par is abruptly narrowed, the keel usually low and is restricted to the last section of the dorsum in some species, reaching the mantle margin in others. [2]
Reproductive system: The penis is usually short, the epiphallus is long. The retractor penis inserts at the boundary between the penis and epiphallus. The vas deferens of specific length opens into the posterior end of the epiphallus. The vaginal accessory glands (usually more than one) are of specific shapes, and are connected by ducts to the vagina or to the point where the vagina enters the atrium. The atrium is small and tubular, with no stimulator inside. Spermatheca are of specific size, the spermathecal duct can be longer or shorter than the spermatheca. [2]
Within the genus Tandonia there are the following 29 species: [3]
Limax maximus, known by the common names great grey slug and leopard slug, is a species of slug in the family Limacidae, the keeled slugs. It is among the largest keeled slugs, Limax cinereoniger being the largest.
Arion lusitanicus, also known by its common name Portuguese slug, is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Arionidae.
Tandonia budapestensis is a species of air-breathing, keeled, land slug, a shell-less terrestrial gastropod mollusks in the family Milacidae.
Arionidae, common name the "roundback slugs" or "round back slugs" are a taxonomic family of air-breathing land slugs, terrestrial pulmonate gastropod mollusks in the superfamily Arionoidea.
Agriolimacidae is a family of small and medium-sized land slugs, or shell-less snails, terrestrial pulmonate gastropod mollusks.
Deroceras is a taxonomic genus of small to medium sized air-breathing land slugs in the family Agriolimacidae.
Geomalacus is a genus of large air-breathing land slugs, terrestrial pulmonate gastropod mollusks in the family Arionidae, the roundback slugs.
Amphidromus is a genus of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Camaenidae. The shells of Amphidromus are relatively large, from 25 mm (0.98 in) to 75 mm (3.0 in) in maximum dimension, and particularly colorful. During the 18th century, they were among the first Indonesian land snail shells brought to Europe by travelers and explorers. Since then, the genus has been extensively studied: several comprehensive monographs and catalogs were authored by naturalists and zoologists during the time period from the early 19th to the mid 20th centuries. Modern studies have focused on better understanding the evolutionary relationships within the group, as well as solving taxonomic problems.
Tandonia nigra is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Milacidae.
Lehmannia is a genus of air-breathing land slugs in the family Limacidae, the keelback slugs. The genus is distributed in Europe and North Africa.
Trigonochlamydidae is a family of air-breathing land slugs, terrestrial gastropod molluscs in the clade Eupulmonata.
Tandonia rustica is a species of air-breathing, keeled, land slug, a shell-less terrestrial gastropod mollusk in the family Milacidae.
Boettgerilla pallens, common name the worm slug, is a European species of air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Boettgerillidae.
Milax gagates, known by the common name greenhouse slug, is a species of air-breathing, keeled, land slug, a shell-less terrestrial gastropod mollusc in the family Milacidae.
The reproductive system of gastropods varies greatly from one group to another within this very large and diverse taxonomic class of animals. Their reproductive strategies also vary greatly, see Mating of gastropods.
Geomalacus anguiformis is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the family Arionidae, the round back slugs.
Carpathica is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Oxychilidae.
Tandonia serbica is a species of keeled air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Milacidae.
The reproductive system of planarians is broadly similar among different families, although the associated structures can vary in complexity.
