Neoepilobocera
''Neoepilobocera gertraudae'' is a species of cave-dwelling crab from Cuba. Classification The species was first described by Gerhard Pretzmann as ''Epilobocera gertraudae'' in 1965. ''N. gertraudae'' is classified in the family Pseudothelphusidae, and is the only species in the genus ''Neoepilobocera''. It is considered by some authorities to be synonymous with the widespread ''Epilobocera cubensis''. Distribution It is only found in karstic caves in Viñales and nearby parts of Pinar del Río Province, Cuba. Description ''Neoepilobocera gertraudae'' differs from the other freshwater crabs of Cuba, all in the genus ''Epilobocera'', by its longer legs and paler coloration, both of which are adaptations to living in caves. It is smaller than ''Epilobocera'', reaching a carapace A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such ...

Pseudothelphusidae
Pseudothelphusidae is a family of freshwater crabs found chiefly in mountain streams in the Neotropics. They are believed to have originated in the Greater Antilles and then crossed to Central America via a Pliocene land bridge. Parasitology Pseudothelpshusids are of significance to humans because many species are secondary hosts for lung flukes of the genus ''Paragonimus''. Predators of pseuthelphusid crabs include the yellow-spotted river turtle and the tufted capuchin. Taxonomy Forty genera are recognised: *'' Allacanthos'' Smalley, 1964 *'' Achlidon'' Smalley, 1964 *'' Brasiliothelphusa'' Magalhães & Türkay, 1986 *'' Camptophallus'' Smalley, 1965 *''Chaceus'' Pretzmann, 1965 *''Disparithelphusa'' Smalley & Adkinson, 1984 *'' Ehecatusa'' Ng & Low, 2010 *''Eidocamptophallus'' Rodríguez & Hobbs, 1989 *''Elsalvadoria'' Bott, 1967 *''Epilobocera'' Stimpson, 1860 *''Eudaniela'' Pretzmann, 1971 *''Fredius'' Pretzmann, 1967 *''Guinotia ''Guinotia'' is a genus of crabs in ...

Viñales
Viñales is a town and municipality in the north-central Pinar del Río Province of Cuba. The town consists mostly of one-story wooden houses with porches. The municipality is dominated by low mountain ranges of the Guaniguanico, Cordillera de Guaniguanico such as Sierra de los Órganos. Typical outcrops known as ''mogotes'' complete the karstic character of the landscape. The town and the Viñales Valley immediately to the north were made a UNESCO World Heritage Site in November 1999 for the karst landscape and traditional agriculture as well as vernacular architecture, crafts and music. History Before European settlement, the area was the home of a remnant Taíno people, Taíno population swelled with runaway slaves.Guerrillero:Pinar del Río"El Templo de los Cimarrones" The area was colonised at the beginning of the 1800s by tobacco growers from the Canary Islands, who settled in the Vuelta Abajo region.

Freshwater Crustaceans Of North America
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh wa ...

Fauna Of Cuba
Cuba ( , ), officially the Republic of Cuba ( es, República de Cuba, links=no ), is an island country comprising the island of Cuba, as well as Isla de la Juventud and several minor archipelagos. Cuba is located where the northern Caribbean Sea, Gulf of Mexico, and Atlantic Ocean meet. Cuba is located east of the Yucatán Peninsula (Mexico), south of both the American state of Florida and the Bahamas, west of Hispaniola (Haiti/Dominican Republic), and north of both Jamaica and the Cayman Islands. Havana is the largest city and capital; other major cities include Santiago de Cuba and Camagüey. The official area of the Republic of Cuba is (without the territorial waters) but a total of 350,730 km² (135,418 sq mi) including the exclusive economic zone. Cuba is the second-most populous country in the Caribbean after Haiti, with over 11 million inhabitants. The territory that is now Cuba was inhabited by the Ciboney people from the 4th millennium BC with the Guanahatabey a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carapace
A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single Plate (animal anatomy), plate which carries the e ...

Troglobite
A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves. These are separate from species that mainly live in above-ground habitats but are also able to live underground (eutroglophiles), and species that are only cave visitors ( subtroglophiles and trogloxenes). Land-dwelling troglobites may be referred to as troglofauna, while aquatic species may be called stygofauna, although for these animals the term ''stygobite'' is preferable. Troglobites typically have evolutionary adaptations to cave life. Examples of such adaptations include slow metabolism, reduced energy consumption, better food usage efficiency, decrease or loss of eyesight (anophthalmia), and depigmentation (absence of pigment in the integument). Conversely, as opposed to lost or reduced functions, many species have evolved elongated antenna and locomotory appendages, in order to better move around and respond to environmental s ...

Adaptation
In biology, adaptation has three related meanings. Firstly, it is the dynamic evolutionary process of natural selection that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process. Thirdly, it is a phenotypic trait or adaptive trait, with a functional role in each individual organism, that is maintained and has evolved through natural selection. Historically, adaptation has been described from the time of the ancient Greek philosophers such as Empedocles and Aristotle. In 18th and 19th century natural theology, adaptation was taken as evidence for the existence of a deity. Charles Darwin proposed instead that it was explained by natural selection. Adaptation is related to biological fitness, which governs the rate of evolution as measured by change in allele frequencies. Often, two or more species co-adapt and co-evolve as they develop adaptations that interlock with those of the oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Freshwater Crab
Around 1,300 species of freshwater crabs are distributed throughout the tropics and subtropics, divided among eight families. They show direct development and maternal care of a small number of offspring, in contrast to marine crabs, which release thousands of planktonic larvae. This limits the dispersal abilities of freshwater crabs, so they tend to be endemic to small areas. As a result, a large proportion are threatened with extinction. Systematics More than 1,300 described species of freshwater crabs are known, out of a total of 6,700 species of crabs across all environments. The total number of species of freshwater crabs, including undescribed species, is thought to be up to 65% higher, potentially up to 2,155 species, although most of the additional species are currently unknown to science. They belong to eight families, each with a limited distribution, although various crabs from other families are also able to tolerate freshwater conditions ( euryhaline) or are secon ...

Pinar Del Río Province
Pinar del Río is one of the provinces of Cuba. It is at the western end of the island of Cuba. Geography The Pinar del Río province is Cuba's westernmost province and contains one of Cuba's three main mountain ranges, the Cordillera de Guaniguanico, divided into the easterly Sierra del Rosario and the westerly Sierra de los Órganos. These form a landscape characterised by steep sided limestone hills (called mogotes) and flat, fertile valleys. One such topographic feature, the Viñales Valley, is a UNESCO World Heritage Site. The northern coast opens to the great Gulf of Mexico, and is lined by the Colorados Archipelago, a string of cays and isles developed on a reef barrier. The westernmost point of Cuba, Cabo San Antonio, is located on the Guanahacabibes Peninsula, which is a National Park and a Biosphere Reserve. History The city was founded by the Spanish as ''Nueva Filipinas'' (New Philippines), and the city was renamed Pinar del Río in 1774. The province was founded i ...
