Abbottella Calliotropis
''Abbottella'' is a genus of Operculum (gastropod), operculate land snails, terrestrial animal, terrestrial gastropod mollusks gastropod in the family Pomatiidae. The generic name ''Abbottella'' is in honor of Dr. W. L. Abbott.This means either William Louis Abbott (1860-1936), or William James Lewis Abbott (1853-1933) Distribution The distribution of ''Abbottella'' includes List of non-marine molluscs of Cuba, Cuba (one species ''Abbottella decolorata'' in Guantánamo, the easternmost point on Cuba) and List of non-marine molluscs of Hispaniola, Hispaniola (all other species). ''Abbottella'' species are a highly endemic group of land snails living in Hispaniola with a single species in eastern Cuba. Most are known chiefly from Puerto Plata (city), Puerto Plata to the Samaná Peninsula in the Cordillera Septentrional that forms the northern coast of the Dominican Republic. A second, lowland group occupies the easternmost portion of the island from the coast west to Santo Doming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puerto Plata (city)
Puerto Plata, officially known as San Felipe de Puerto Plata; () is a major coastal city in the Dominican Republic, and capital of the province of Puerto Plata. The city is a major trading port. Puerto Plata has resorts such as Playa Dorada and Costa Dorada, which are located east of the city proper. There are 100,000 hotel beds in the city. The first aerial tramway of the Caribbean is located in Puerto Plata, in which visitors can ride up to the Pico Isabel de Torres, a 793-meter (2600-foot) high mountain within the city. The city's history dates back to the early 16th century, when Spanish colonists founded a small colonial settlement in the region. During the first decades of the existence of the Captaincy General of Santo Domingo, the settlement was considered the main commercial and maritime port of the island. In 1605, it was depopulated and destroyed by order of Philip III of Spain to counter raids by English privateers and pirates; a hundred years later, the city was repop ...

Sculpture (mollusc)
Sculpture is a feature of many of the shells of mollusks. It is three-dimensional ornamentation on the outer surface of the shell, as distinct from either the basic shape of the shell itself or the pattern of colouration, if any. Sculpture is a feature found in the shells of gastropods, bivalves, and scaphopods. The word "sculpture" is also applied to surface features of the aptychus of ammonites, and to the outer surface of some calcareous opercula of marine gastropods such as some species in the family Trochidae. Sculpture can be concave or convex, incised into the surface or raised from it. Sometimes the sculpture has microscopic detailing. The term "sculpture" refers only to the calcareous outer layer of shell, and does not include the proteinaceous periostracum, which is in some cases textured even when the underlying shell surface is smooth. In many taxa, there is no sculpture on the shell surface at all, apart from the presence of fine growth lines. The sculp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropod Shell
The gastropod shell is part of the body of many gastropods, including snails, 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, ostracum, is typically made of calcium carbonate (CaCO3) precipitated into an organic matrix ...

Monophyletic
In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent common ancestor (or more precisely an ancestral population), i.e. excludes non-descendants of that common ancestor # the grouping contains all the descendants of that common ancestor, without exception Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic'' grouping meets 1. but not 2., thus consisting of the descendants of a common ancestor, excepting one or more monophyletic subgroups. A '' polyphyletic'' grouping meets neither criterion, and instead serves to characterize convergent relationships of biological features rather than genetic relationships – for example, night-active primates, fruit trees, or aquatic insects. As such, these characteristic features of a polyphyletic grouping ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radula
The radula (; : radulae or radulas) is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus. The radula is unique to the mollusks, and is found in every class of mollusk except the bivalves, which instead use cilia, waving filaments that bring minute organisms to the mouth. Within the gastropods, the radula is used in feeding by both herbivorous and carnivorous snails and slugs. The arrangement of teeth ( denticles) on the radular ribbon varies considerably from one group to another. In most of the more ancient lineages of gastropods, the radula is used to graze, by scraping diatoms and other microscopic algae off rock surfaces and other substrates. Predatory marine snails such as the Naticidae use the radula plus an acidic secretion to bore through the shell of other mollusks. Other predatory marine snails, ...

Tiburon Peninsula
The Tiburon Peninsula (), or simply "the Tiburon" (''le Tiburon''), is a region of Haiti encompassing most of Haiti's southern coast. It starts roughly at the southernmost point of the Haiti-Dominican Republic border and extends westward near Cuba, forming a large headland. Three of Haiti's ten Administrative divisions of Haiti, departments are located entirely within the region. They are the departments of Grand'Anse (department), Grand'Anse, Nippes and Sud (department), Sud. A large part of Ouest (department), Ouest Departments of Haiti, department is also located in the region, with the capital, Port-au-Prince serving as the line of demarcation between central Haiti and the south. Half of Sud-Est (department), Sud-Est is also located within the Tiburon Peninsula. The mountains on the peninsula are known as the Massif de la Hotte.

Isla Beata
Beata Island () is a small island on the Caribbean Sea, located southwest from Cape Beata. Some southwest of it lies the smaller Alto Velo Island. It is politically part of the Dominican Republic, and is roughly triangle-shaped and fairly flat, with an approximate area of . The island, along with Alto Velo Island, is part of the UNESCO Biosphere Reserve named the Jaragua National Park. History Beata Island was discovered by Europeans during the second voyage of Christopher Columbus in 1494. Originally populated by Taíno natives, the island became a colonial asset of the Captaincy General of Santo Domingo and the greater Spanish Empire. The island was the site of various military engagements between the Spanish and roving pirates. Geography The landscape is somewhat varied, with mangrove swamps on parts of the North shore, sandy coves and beaches on the west coast. Most of the interior of the island is covered by various subtypes of xeric semi-deciduous limestone forests. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
