L'Aquila
L'Aquila ( , ) is a city and ''comune'' in central Italy. It is the capital city of both the Abruzzo region and of the Province of L'Aquila. , it has a population of 70,967 inhabitants. Laid out within medieval walls on a hill in the wide valley of the Aterno river, it is surrounded by the Apennine Mountains, with the Gran Sasso d'Italia to the north-east. L'Aquila sits upon a hillside in the middle of a narrow valley; tall snow-capped mountains of the Gran Sasso massif flank the town. A maze of narrow streets, lined with Baroque and Renaissance buildings and churches, open onto elegant piazzas. Home to the University of L'Aquila, it is a lively college town and, as such, has many cultural institutions: a repertory theatre, a symphony orchestra, a fine-arts academy, a state conservatory, a film institute. There are several ski resorts in the surrounding province (Campo Imperatore, Ovindoli, Pescasseroli, Roccaraso, Scanno). Geography Close to the highest of the Apennine s ...

Geomitridae
Geomitridae is a Taxonomy (biology), taxonomic Family (biology), family of small to medium-sized air-breathing land snails, Terrestrial molluscs, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.MolluscaBase eds. (2021). MolluscaBase. Geomitridae C.R. Boettger, 1909. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=994707 on 2021-02-01 Anatomy The family is characterized by the presence of a free right ommatophoral retractor (passing outside the peni-oviducal angle) and a double stimulatory apparatus. A free right ommatophoral retractor has been linked to adaptation to xeric habitats Taxonomy The family Geomitridae is subdivided in the following subfamilies (according to Razkin ''et al.'', 2015) *Subfamily Geomitrinae ** tribe Cochlicellini Schileyko, 1972 ** tribe Geomitrini C.

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.

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.

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.

Terrestrial Animal
Terrestrial animals are animals that live predominantly or entirely on land (e.g. cats, dogs, ants, spiders), as compared with aquatic animals, which live predominantly or entirely in the water (e.g. fish, lobsters, octopuses), and amphibians, which rely on a combination of aquatic and terrestrial habitats (e.g. frogs and newts). Some groups of insects are terrestrial, such as ants, butterflies, earwigs, cockroaches, grasshoppers and many others, while other groups are partially aquatic, such as mosquitoes and dragonflies, which pass their larval stages in water. Terrestrial animals tend to be more developed and intelligent than aquatic animals. Terrestrial classes The term "terrestrial" is typically applied to species that live primarily on the ground, in contrast to arboreal species, which live primarily in trees. There are other less common terms that apply to specific groups of terrestrial animals: *Saxicolous creatures are rock dwelling. "Saxicolous" is derived from t ...

Land Snail
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial gastropod mollusks that have shells (those without shells are known as slugs). However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water. Land snails are a polyphyletic group comprising at least ten independent evolutionary transitions to terrestrial life (the last common ancestor of all gastropods was marine). The majority of land snails are pulmonates that have a lung and breathe air. Most of the non-pulmonate land snails belong to lineages in the Caenogastropoda, and tend to have a gill and an operculum. The largest clade of land snails is the Cyclophoroidea, with more than 7,000 species. Many of these operculate land snails live in habitats or microhabitats ...

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] |
Marianna Paulucci
Marquise Marianna Panciatichi Ximenes d’Aragona Paulucci (3 February 1835 – 7 December 1919) was an Italian malacologist who also made contributions to botany and ornithology. A specialist in non-marine molluscs, she published 32 malacological works, describing two genera and 159 species, and is commemorated in around 40 scientific names of organisms: primarily molluscs, as well as the fossil shark ''Scyllium pauluccii'' and the bird subspecies '' Sylvia atricapilla pauluccii''. Life and work She was born in Florence into a noble family: the daughter of and Giulia De Saint Seigne. In 1853 she married Marquis Alessandro Anafesto Paulucci, a botanist and son of Filippo Paulucci. In 1866 she published the first scientific work on the fossil gastropod Murex veranyi. In 1887, after her husband's death, and ten years after her father died, the Marquise had to abandon her studies as well as her collections so she could devote her energies almost entirely to the administration of h ...
