Carpathica
''Carpathica'' is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Oxychilidae. Distribution Distribution of ''Carpathica'' include south-eastern Europe and Turkey. Description Animal cannot withdraw into the shell. The shell is with 0.5-2 whorls. The last whorl is much inflated. Reproductive system: Penis is more or less long, usually cylindrical, with appendix (flagellum) at its terminal end. Vas deferens is inserting laterally (subterminally). Retractor connects at appendix. Vagina is usually shorter, surrounded by a vaginal gland in its posterior part. Spermatheca duct is usually short and usually inserting in the zone covered by the vaginal gland. The spermatheca is spherical or ovoid. Oviduct is usually short and sometimes thinner than penis and vagina. Atrium is short. ''Carpathica'' differs from ''Daudebardia'' in the presence of an appendix or flagellum at the apical end of the penis; vas deferens inserts subter ...

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.

Alexandru Vasile Grossu
Alexandru is the Romanian language, Romanian form of the name Alexander. Common diminutives are Alecu, Alex (other), Alex, and Sandu (other), Sandu. Origin Etymology, Etymologically, the name is derived from the Greek language, Greek "Αλέξανδρος" (Aléxandros), meaning "defending men" or "protector of men", a compound of the verb "ἀλέξω" (alexō), "to ward off, to avert, to defend" and the noun "ἀνδρός" (andros), genitive of "ἀνήρ" (anēr), "man". It is an example of the widespread motif of Greek (or Indo-European more generally) names expressing "battle-prowess", in this case the ability to withstand or push back an enemy shield wall, battle line. The earliest attested form of the name is the Mycenaean Greek feminine noun ''a-re-ka-sa-da-ra'', (transliterated as ''Alexandra''), written in Linear B syllabic script. The name was one of the titles ("epithets") given to the Greek goddess Hera and as such is usually taken to mean "one wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reproductive System Of Gastropods
The reproductive system of gastropods (slugs and snails) varies greatly from one group to another within this very large and diverse taxonomic class of animals. Their reproductive strategies also vary greatly, see Mating of gastropods. In many marine gastropods there are separate sexes (male and female); most terrestrial gastropods however are hermaphrodites. Courtship is a part of the behaviour of mating gastropods. In some families of pulmonate land snails, one unusual feature of the reproductive system and reproductive behavior is the creation and utilization of love darts, the throwing of which has been identified as a form of sexual selection. Gastropods are defined as snails and slugs, belonging to a larger group called Molluscs. Gastropods have unique reproductive systems, varying significantly from one taxonomic group to another. They can be separated into three categories: marine, freshwater, and land. Reproducing in marine or freshwater environments makes getting s ...

Last Whorl
The body whorl is part of the morphology of the shell in those gastropod mollusks that possess a coiled shell. The term is also sometimes used in a similar way to describe the shell of a cephalopod mollusk. In gastropods In gastropods, the body whorl, or last whorl, is the most recently formed and largest whorl (or revolution) of a spiral or helical shell, terminating in the aperture. It is called the "body whorl" because most of the body of the soft parts of the animal fits into this whorl. The proportional size of the body whorl in gastropod shells differs greatly according to the actual shell morphology. For shells in which the rate of whorl expansion of each revolution around the axis is very high, the aperture and the body whorl are large, and the shell tends to be low spired. The shell of the abalone is a good example of this kind of shell. The opposite tendency can sometimes create a high spire with very little whorl increase per revolution. In these instances, e.g. ...

Whorl (mollusc)
A whorl is a single, complete 360° revolution or turn in the spiral growth of a mollusc shell. A spiral configuration of the shell is found in numerous gastropods, but it is also found in shelled cephalopods including ''Nautilus'', ''Spirula'' and the large extinct subclass of cephalopods known as the ammonites. A spiral shell can be visualized as consisting of a long conical tube, the growth of which is coiled into an overall helical or planispiral shape, for reasons of both strength and compactness. The number of whorls which exist in an adult shell of a particular species depends on mathematical factors in the geometric growth, as described in D'Arcy Wentworth Thompson's classic 1917 book ''On Growth and Form'', and by David Raup. The main factor is how rapidly the conical tube expands (or flares-out) over time. When the rate of expansion is low, such that each subsequent whorl is not that much wider than the previous one, then the adult shell has numerous whorls. When the ...
