Geomalacus malagensis is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the family Arionidae, the round back slugs.
Distribution of Geomalacus malagensis include southern Spain and Gibraltar. [2]
This slug species is pale beige-greenish to beige-grey, sometimes also yellowish-orange, with blackish narrow lateral bands having clearly marked upper edges and blurry lower edges, running from posterior end to frontal section of mantle, above the pneumostome. [2] The shape of the slug is elongate, dorso-ventrally flattened (oval in transversal cut). [2] The head is very short (only 2–3 mm protruding from under the mantle). [2] Tentacles are brown and long. [2] Mantle length covers 35% of body. [2] There are 26 grooves between medial line of dorsum and pneumostome. [2] Sole is dirty cream, transparent (viscera visible in live slugs), medial section narrower than lateral sections and slightly concave. [2] Mucus is colourless and thin, also when irritated, sometimes with orange hue. [2] Mucus secreted onto the ground while crawling breaks into thin threads and coagulates into a unique spider-web like pattern, not seen in Arion species. [2]
The length of the body is up to 80 × 10.5 mm (preserved 58 × 11 mm). [2]
Geomalacus malagensis is frequent on calcareous soil, in gardens, shrubland and open forests. [2]
It seems to feed on fruits and other soft parts of plants. [2]
Sexually mature slugs are found in spring and autumn. [2]
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.
The red slug, also known as the large red slug, chocolate arion and European red slug, is a species of land slug in the family Arionidae, the roundback slugs.
Schizoglossa novoseelandica is a predatory species of air-breathing land slug or semi-slug, a terrestrial gastropod mollusc in the family Rhytididae. It is the type species of the genus Schizoglossa and is found only in New Zealand. The survival of this species is not threatened; it is not listed in the 2009 IUCN Red List nor is it in the 2005 New Zealand Threat Classification System lists.
The black slugArion aterL. is a large terrestrial gastropod mollusk in the family Arionidae, the round back slugs. Land slugs lack shells like other terrestrial mollusks. Without such shells, slugs produce unappetizing mucus, that may also contain toxins—to deter predators. Terrestrial slugs produce two other forms of mucus that facilitate locomotion and prevent death from drying. Such mollusks are hermaphroditic. Slugs most often function as decomposers but are also often omnivores. Arion ater is one such slug, decomposing organic matter, preying on other organisms, and consuming vegetative matter including agricultural crops. Native to Europe, the black slug is an invasive species in Australia, Canada, and the United States.
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.
Arion fuscus, also known as the "Dusky Arion", is a species of small air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Arionidae, the roundback slugs.
Arion distinctus is a species of air-breathing land slug in the family Arionidae, sometimes known as the roundback slugs. It is a terrestrial pulmonate gastropod mollusc. Several vernacular names exist, but it is unclear if they are much in use: brown soil slug, common garden slug, darkface arion, Mabille's orange-soled slug, April slug.
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.
The Kerry slug or Kerry spotted slug is a species of terrestrial, pulmonate, gastropod mollusc. It is a medium-to-large sized, air-breathing land slug in the family of roundback slugs, Arionidae.
Slug, or land slug, is a common name for any apparently shell-less terrestrial gastropod mollusc. The word slug is also often used as part of the common name of any gastropod mollusc that has no shell, a very reduced shell, or only a small internal shell, particularly sea slugs and semislugs.
Arion circumscriptus, common name brown-banded arion, is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Arionidae.
Arion fasciatus, also known by its common name the Orange-banded Arion, is a species of air-breathing, completely shell-less, land slug, a terrestrial pulmonate gastropod mollusk in the family Arionidae, the round-back slugs. The species was first described by Sven Nilsson in 1823.
Arion hortensis, also known by its common name the "garden slug", "small striped slug" or "black field slug" is a species of small air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Arionidae, the roundback slugs.
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 red triangle slug is a species of large air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Athoracophoridae, the leaf-veined slugs.
Geomalacus anguiformis is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the family Arionidae, the round back slugs.
Geomalacus oliveirae is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the family Arionidae, the round back slugs.
Ariunculus is a genus of air-breathing land slugs in the family Arionidae, the roundback slugs. Sometimes it has been considered as a subgenus of Arion, and sometimes the subgenus Ichnusarion has been raised to generic rank.
Prophysaon andersoni, common name the reticulate taildropper, is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Arionidae, the roundback slugs.
