Mario Lessona
Mario Lessona (18 December 1855 in Genoa – 25 December 1911 in Turin) was an Italian zoologist and malacologist. He was the son of the prominent natural scientist and senator Michele Lessona and his wife Adele Masi Lessona, who was very much involved in her husband's work, particularly in making translations. A son of Adele Lessona by an earlier marriage was the painter and malacologist Carlo Pollonera, with whom Mario published a monograph on Italian slugs. Mario also coauthored various scientific works with his brother-in-law, the zoologist and senator Lorenzo Camerano. Biography In the 1880s, Lessona was an assistant professor of zoology at the University of Messina, and then a teacher of natural history at secondary schools in Venice and Carmagnola. In the 1890s he worked as a teacher in the Fornaris-Morocco boarding school in Turin. He published on malacology and comparative anatomy, as well as writing several books of natural history and geography for schools. He also edit ...

Carlo Pollonera
Carlo Pollonera (Alexandria, Egypt, March 27, 1849 – Turin, June 17, 1923) was an Italian painter, particularly of landscapes, and also an important malacologist. Biography Carlo Pollonera's father, Giovanni B. Pollonera, was a lawyer in Alexandria. He died when Carlo was a child, after which his mother returned to Italy (Genoa) and remarried. As a seventeen-year-old, Carlo fought with Garibaldi on the Trentino campaign of 1866. In 1865, the family had moved to Turin, where Pollonera began studying painting with Alberto Maso Gilli. He enrolled at the Accademia Albertina and studied under Gamba and Andrea Gastaldi. Pollonera was a rebellious pupil, wanting to paint exactly what he saw, rather than, for instance, changing a distracting background. This principle not to improve on what he saw remained a hallmark of his painting throughout Pollonera's career. After four years with Gastaldi, in 1873 he switched to study in the private school of Antonio Fontanesi. In January 1875, he ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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.

Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Mollusk
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Limacidae
Limacidae, also known by their common name the keelback slugs, are a taxonomic family of medium-sized to very large, air-breathing land slugs, terrestrial pulmonate gastropod molluscs in the superfamily Limacoidea. Distribution The distribution of the family Limacidae is the western Palearctic. There are 28 species of Limacidae in Russia and adjacent countries. Anatomy In this family, the number of haploid chromosomes lies between 21 and 25 and also lies between 31 and 35 (according to the values in this table).Barker G.

Malta
Malta ( , , ), officially the Republic of Malta ( mt, Repubblika ta' Malta ), is an island country in the Mediterranean Sea. It consists of an archipelago, between Italy and Libya, and is often considered a part of Southern Europe. It lies south of Sicily (Italy), east of Tunisia, and north of Libya. The official languages are Maltese and English, and 66% of the current Maltese population is at least conversational in the Italian language. Malta has been inhabited since approximately 5900 BC. Its location in the centre of the Mediterranean has historically given it great strategic importance as a naval base, with a succession of powers having contested and ruled the islands, including the Phoenicians and Carthaginians, Romans, Greeks, Arabs, Normans, Aragonese, Knights of St. John, French, and British, amongst others. With a population of about 516,000 over an area of , Malta is the world's tenth-smallest country in area and fourth most densely populated sovereign cou ...
