Veronicellidae
The Veronicellidae, also known by their common name the leatherleaf slugs, are a family of pulmonate terrestrial slugs. The herbivorous molluscs occur mainly in the tropical and subtropical areas of America, Asia and Africa. They act as intermediate hosts of the rat lung worm ''Angiostrongylus costaricensis'', and act as a vector for other human diseases. They also cause significant damage to crops. Description The dorsal surface of these slugs is entirely covered by the mantle or hyponota. These mollusks have a posterior located anus, eyes on contractile (not retractile) tentacles, and no lung or pulmonary organ. In these aspects they are anatomically distinct from most other types of terrestrial slugs, which typically belong to the order Stylommatophora, and which have a forward located anus, and retractile tentacles. The closely related members of the family Onchidiidae differ from the Veronicellidae by having a pulmonary sac, or lung. Distribution Members of the famil ...

Veronicella Sloanei
''Veronicella sloanii'', common name, commonly called the pancake slug, is a species of air-breathing land slug, a Terrestrial molluscs, terrestrial, pulmonate gastropod mollusk in the family Veronicellidae, the leatherleaf slugs. Description When extended, this slug can attain a length of 12 cm (5 in.). It is highly variable in coloration and positive identification depends on dissection and inspection of the Reproductive system of gastropods, genitalia. It is usually very pale in color, ranging from mottle pale yellow, cream to white. It may have irregular black spotting or speckling all over the dorsal surface that may coalesce into two poorly defined bands running down either side of the body; in the juveniles, these two bands may be clearer and better defined as grey bands, especially anteriorly. Occasionally the slug can be mostly brownish. The only constant color character among different Caribbean island populations is the eye stalk, which is bluish grey with a lig ...

Slug
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 (this is in contrast to the common name ''snail'', which applies to gastropods that have a coiled shell large enough that they can fully retract their soft parts into it). Various taxonomic families of land slugs form part of several quite different evolutionary lineages, which also include snails. Thus, the various families of slugs are not closely related, despite a superficial similarity in the overall body form. The shell-less condition has arisen many times independently as an example of convergent evolution, and thus the category "slug" is polyphyletic. Taxonomy Of the six orders of Pulmonata, two – the Onchidiacea and Soleolifera – solely comprise slugs. A third family, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Non-marine Molluscs Of Dominica
The non-marine molluscs of Dominica are species of land and freshwater molluscs, i.e. land snails, land slugs and one small freshwater clam that are part of the wildlife of Dominica, an island in the Lesser Antilles. In malacology, the non-marine molluscs of an area are traditionally listed separately from the marine molluscs (those molluscs that live in full-salinity saltwater). Dominica is a Caribbean island, part of the Windward Island chain of the Lesser Antilles. Fifty-five species of non-marine molluscs have been found in the wild in Dominica, including sixteen endemic species of land snails, species which occur nowhere else on Earth. Dominica is a mountainous, , volcanic, tropical island. It is undeveloped compared with most other Caribbean islands, and it is known for its wildlife and unspoiled natural landscapes. The rugged terrain includes a great deal of tropical rainforest, numerous rivers, and several officially protected areas, including Morne Trois Pitons National ...

Laevicaulis Alte
''Laevicaulis alte'', or the tropical leatherleaf, is a species of tropical land slug, a terrestrial pulmonate gastropod mollusk in the family Veronicellidae, the leatherleaf slugs. Description ''Laevicaulis alte'' is a round, dark-coloured slug with no shell, long. Its skin is slightly tuberculated. The central keel is beige in colour. This slug has a unique, very narrow foot; juvenile specimens have a foot wide and adult specimens have a foot that is only wide. The tentacles are small, long, and they are only rarely extended beyond the edge of the mantle. Parasites This slug is an intermediate host for ''Angiostrongylus cantonensis'', the rat lungworm, a round worm, the most common cause of eosinophilic meningoencephalitis. Predators ''Laevicaulis alte'' is eaten by the frog '' Rana tigrina''. Distribution The species is probably indigenous to Africa, both western Africa and eastern Africa, particularly Tanzania.Rowson B., Warren B. H. & Ngereza C. F. (2010). "Ter ...

Pulmonate
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. The taxon Pulmonata as traditionally defined was found to be polyphyletic in a molecular study per Jörger ''et al.'', dating from 2010. Pulmonata are known from the Carboniferous Period to the present. Pulmonates have a single atrium and kidney, and a concentrated, symmetrical, nervous system. The mantle cavity is located on the right side of the body, and lacks gills, instead being converted into a vascularised lung. Most species have a shell, but no operculum, although the group does also include several shell-less slugs. Pulmonates are hermaphroditic, and some groups possess love darts.

Angiostrongylus Costaricensis
''Angiostrongylus costaricensis'' is a species of parasitic nematode and is the causative agent of abdominal angiostrongyliasis in humans. It occurs in Latin America and the Caribbean. Hosts Rodents are the normal definitive hosts, especially the cotton rat. Aberrant infections have occurred in many other mammals including humans. Infection of mammalian hosts occurs via ingestion of L3 larvae in mollusc tissue (e.g. undercooked or raw snails or accidentally on produce) or possibly food contaminated with slime containing such larvae. Molluscs are the intermediate host and are infected through ingestion or penetration of the foot by L1 infective larvae from infected feces. * '' Limax maximus'' * Slugs from the family Veronicellidae Pathology Pathology is due to both the adults and the eggs. Adults in the ileo-caecal arterioles cause an inflammatory (eosinophilic) response in humans. In the Cotton Rat the adult worms cause local haemorrhages. The intestinal wall is also af ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
