Labyrinthus Leucodon
''Labyrinthus leucodon'' is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Labyrinthidae. Description The periphery of the shell of this species is acutely angulated. The spire is normally elevated, and the sides of the spire are flat to slightly rounded. The shell aperture is moderately deflected. Within the aperture, the high, simple parietal lamella starts descending before it runs into the parietal lip. The basal lip has a broad, prominent knob. The lower palatal tooth is a prominent, crescentic lamella, with strong lateral buttresses. The upper palatal lip often has a small tuberculate denticle. The periostracum is brownish in color, occasionally speckled with greenish yellow. Distribution This species occurs in: * Venezuela Solem A.

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

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 d ...

List Of Molluscs Of Falcón State, Venezuela
Falcón State is a state on the coast in the northwestern part of the country of Venezuela. Falcón State covers a total surface area of 24,800 km² and, in 2010, had an estimated population of 950,057. There are four national parks in the state: the Médanos de Coro National Park, the Cueva de la Quebrada del Toro, Morrocoy, and Juan Crisóstomo Falcón National Park. A large number of species of terrestrial, freshwater and marine molluscs are found in the wild in Falcón State. However, most of the marine mollusks in the area are the same species that occur elsewhere in the Caribbean faunal zone. This is a partial list of the molluscs of Falcón State. The families are listed alphabetically within the classes. Whether the family is marine, terrestrial or freshwater is indicated after the name of the family, but there is no attempt to separate marine species from non-marine species.

Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments and the Capital District of Bogotá, the country's largest city. It covers an area of 1,141,748 square kilometers (440,831 sq mi), and has a population of 52 million. Colombia's cultural heritage—including language, religion, cuisine, and art—reflects its history as a Spanish colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by enslaved Africans, as well as with those of the various Amerindian civilizations that predate colonization.

Yaracuy
Yaracuy State ( es, link=no, Estado Yaracuy, ;) is one of the 23 states of Venezuela. It is bordered by Falcón in the north, in the west by Lara, in the south by Portuguesa and Cojedes and in the east by Cojedes and Carabobo. Its geography is mountainous: the Andes range ends there, and the Coastal Range begins. It is split by two mountainous systems, the Sierra de Aroa on the North and the Sierra de Nirgua. In between lies the agricultural land drained by the Yaracuy River. Most cities and towns are in this valley, including its capital San Felipe. The economy of Yaracuy is mostly agricultural (sugar cane, corn, cattle raising). Some manufacturing can be found in Yaritagua area and Chivacoa, usually in agribusiness. History The written history of Yaracuy begins in the year 1530, with the passage of the German Nicolás Federman, Lieutenant of Governor Welser of Augsburg. In his travel report through the Belzaresque jurisdiction, he qualifies it as Valle de las Damas. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mérida (state)
The State of Mérida commonly known simply as Mérida ( es, Estado Bolivariano de Mérida, ) is one of the 23 states of Venezuela. The state capital is Mérida, in the Libertador Municipality. Located in the Western Andean Region, Mérida State covers a total surface area of , making it the fifteenth-largest in Venezuela. In 2011, had a census population of 828,592, the fourteenth most populous. History Pre-Colonial According to recent studies in archaeology, history and anthropology, The Andean region seems to have been inhabited since very remote times (perhaps several thousand years) by unknown groups that have left very few traces. Then, around our era, another ethnic group of great cultural importance arrives in the region, perhaps of Chibcha origin, since they share with these their mythology, funeral and settlement patterns, housing construction, agricultural techniques, etc. When the Spanish arrive in the Andean Cordillera it will be with this second group you wil ...

Venezuelan Capital District
The Capital District ( es, Distrito Capital) is a federal district of Venezuela. It has an area of 433 km2 and there is only one administrative division (''municipio''), Libertador, which contains about half of Caracas, the Venezuelan capital city, which is also the seat of the three branches of the federal government of Venezuela. The population in 2004 was 2,073,768. The District borders on the states of Vargas and Miranda. Government Formerly it had its own local government with a governor, but the constitutional reform of 1999 abolished the district government and created instead the Metropolitan District of Caracas, with jurisdiction over the territory of the District and also four adjacent ''municipios'' (Baruta, Chacao, el Hatillo and Sucre) in Miranda which all together form the city. On 13 April 2009, the National Assembly passed a law creating the figure of a head of government for the district which would be designated by the President. On 14 April 2009, ...

Periostracum
The periostracum ( ) is a thin, organic coating (or "skin") that is the outermost layer of the shell of many shelled animals, including molluscs and brachiopods. Among molluscs, it is primarily seen in snails and clams, i.e. in gastropods and bivalves, but it is also found in cephalopods such as ''Allonautilus scrobiculatus''. The periostracum is an integral part of the shell, and it forms as the shell forms, along with the other shell layers. The periostracum is used to protect the organism from corrosion. The periostracum is visible as the outer layer of the shell of many molluscan species from terrestrial, freshwater, and marine habitats, and may be seen in land snails, river mussels, and other kinds of freshwater bivalves, as well as in many kinds of marine shelled molluscs. The word ''periostracum'' means "around the shell", meaning that the periostracum is wrapped around what is usually the more calcareous part of the shell. Technically, the calcareous part of the ...
