Pomacea Haustrum
''Pomacea haustrum'', common name the titan applesnail, is a species of large freshwater snail with an operculum, an aquatic gastropod mollusk in the family Ampullariidae, the applesnails. Original description ''Pomacea haustrum'' was originally described under the name ''Ampullaria haustrum'' by Lovell Augustus Reeve in his book '' Conchologia Iconica'', in 1856. In Reeve's original text, (the type description) reads as follows: It is difficult to identify even the general region of the type locality for this species. The type locality was given as the Río Marañón, Brazil, but this river is in Peru, joining with the Rio Ucayali above Iquitos to become the Rio Solimões, which in turn joins with the Rio Negro to become the Amazon River of Brazil. Some of the first Europeans to explore the region in the sixteenth century, however, referred to the Amazon River as El Río Marañón, and some nineteenth century maps refer to the entire Amazon as the Marañón.

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 ...

Colonial Brazil
Colonial Brazil ( pt, Brasil Colonial) comprises the period from 1500, with the arrival of the Portuguese, until 1815, when Brazil was elevated to a kingdom in union with Portugal as the United Kingdom of Portugal, Brazil and the Algarves. During the early 300 years of Brazilian colonial history, the economic exploitation of the territory was based first on brazilwood (''pau brazil'') extraction (16th century), which gave the territory its name; sugar production (16th–18th centuries); and finally on gold and diamond mining (18th century). Slaves, especially those brought from Africa, provided most of the work force of the Brazilian export economy after a brief period of Indian slavery to cut brazilwood. In contrast to the neighboring Spanish possessions, which had several viceroyalties with jurisdiction initially over New Spain (Mexico) and Peru, and in the eighteenth century expanded to viceroyalties of the Río de la Plata and New Granada, the Portuguese colony of Brazil ...

Amazon River
The Amazon River (, ; es, Río Amazonas, pt, Rio Amazonas) in South America is the largest river by discharge volume of water in the world, and the disputed longest river system in the world in comparison to the Nile. The headwaters of the Apurímac River on Nevado Mismi had been considered for nearly a century as the Amazon basin's most distant source, until a 2014 study found it to be the headwaters of the Mantaro River on the Cordillera Rumi Cruz in Peru. The Mantaro and Apurímac rivers join, and with other tributaries form the Ucayali River, which in turn meets the Marañón River upstream of Iquitos, Peru, forming what countries other than Brazil consider to be the main stem of the Amazon. Brazilians call this section the Solimões River above its confluence with the Rio Negro forming what Brazilians call the Amazon at the Meeting of Waters ( pt, Encontro das Águas) at Manaus, the largest city on the river. The Amazon River has an average discharge of about – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rio Negro (Amazon)
The Rio Negro ( pt, Rio Negro, br ; es, Río Negro} "''Black River''"), or Guainía as it is known in its upper part, is the largest left tributary of the Amazon River (accounting for about 14% of the water in the Amazon basin), the largest blackwater river in the world, and one of the world's ten largest rivers by average discharge. Geography Upper course The source of the Rio Negro lies in Colombia, in the Department of Guainía where the river is known as the ''Guainía River''. The young river generally flows in an east-northeasterly direction through the Puinawai National Reserve, passing several small indigenous settlements on its way, such as Cuarinuma, Brujas, Santa Rosa and Tabaquén. After roughly 400 km the river starts forming the border between Colombia's Department of Guainía and Venezuela's Amazonas State. After passing the Colombian community of Tonina and Macanal the river turns Southwest. Maroa is the first Venezuelan town the river passes. 1 ...

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...
