Geomalacus anguiformis is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the family Arionidae, the round back slugs.
This species occurs in south Portugal (Serra de Monchique) and central Spain. [2]
The slug is dark grey with brown hue. [2] It has lighter sides and two light colour bands with dark lower margins running along both sides of the mantle. [2] Mantle is elliptical, extending to tentacles in anterior part. [2] Tentacles are nearly black, thick and not very long. [2] When crawling, the slug has not always a regularly cylindrical shape, there are depressions and dilatations. [2] Sole is light creamy with darker medial zone, with yellowish or greenish hue. [2] Mucus is yellow. [2] Geomalacus anguiformis is 60 mm long (preserved 30 mm). [2]
Shell is elliptical, solid, upper side convex and lower side flat. [2]
The reproductive system is diagnostic feature: Geomalacus anguiformis has atrial diverticulum shorter than spermatheca duct [3] while Kerry slug Geomalacus maculosus has atrial diverticulum longer than spermatheca duct. [3] Geomalacus anguiformis has penis long, vas deferens very thin, spermatheca oval with long duct. [2] Geomalacus anguiformis differs from Geomalacus oliveirae in its atriopenis inserting at the prolongation of the atrial long axis (not laterally). [2]
Geomalacus anguiformis was found in olive plantations, under bark. [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.
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.
The Spanish slug, also known by its scientific name Arion vulgaris, more commonly known in English-speaking countries under the incorrectly applied Latin name Arion lusitanicus, is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Arionidae, the roundback slugs.
