Dermophis Parviceps
''Dermophis parviceps'' is a species of caecilian in the family Dermophiidae. It is found in Costa Rica and Panama, and possibly in Colombia, depending on the source. Common names slender caecilian and La Loma caecilian have been coined for it. Description Specimens from Costa Rica measure in total length and have 85–102 primary and 11–26 secondary annuli; the annular grooves lack dark pigment seen in ''Dermophis mexicanus'' and ''Dermophis oaxacae''. The body is slender. The eyes can be seen through the skin. The head is pinkish, contrasting with the purplish-gray body. Habitat and conservation ''Dermophis parviceps'' occurs in humid montane and lowland forest at elevations of above sea level. It is a subterranean species that can be found as deep as below the soil surface, but also under logs or in leaf litter. It is probably viviparous Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a ...

Heredia Province
Heredia () is a province of Costa Rica. It is in the north-central part of the country. As a result, the province covers areas as diverse as the agriculture-rich Northern plains to the more metropolitan areas such as the city of Heredia in the Central Valley. It contains several major environmentally important areas such as the Braulio Carrillo National Park and the Sarapiqui River. The capital is the city of Heredia. To the north it borders Nicaragua, to the east is the province Limón, to the south the province San José, and to the west Alajuela. Geography The province covers an area of 2,657 km². The province is home to a variety of environments, including primary forests, tropical dry forests, and montane forests. Demographics In 1850, the province had a population of approximately 13,390. As of 2011, it has a population of 433,677. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Taxa Named By Emmett Reid Dunn
In biology, a taxon (back-formation from ''Taxonomy (biology), taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular Taxonomic rank, ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of bio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amphibians Of Costa Rica
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Viviparous
Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproductive mode in which females lay developing eggs that complete their development and hatch externally from the mother. The term 'viviparity' and its adjective form 'viviparous' derive from the Latin ''vivus'' meaning "living" and ''pario'' meaning "give birth to". Reproductive mode Five modes of reproduction have been differentiated in animals based on relations between zygote and parents. The five include two nonviviparous modes: ovuliparity, with external fertilisation, and oviparity, with internal fertilisation. In the latter, the female lays zygotes as eggs with a large yolk; this occurs in all birds, most reptiles, and some fishes. These modes are distinguished from viviparity, which covers all the modes that result in live birth: *Histotrophic viviparity: the zygotes develop in the female's oviducts, but find their nutrients by oophagy ...

Dermophis Oaxacae
''Dermophis oaxacae'', also known Oaxacan caecilian, is a species of caecilian in the family Dermophiidae.

Dermophis Mexicanus
''Dermophis mexicanus'', also known commonly as the Mexican burrowing caecilian or the Mexican caecilian, and locally as the tapalcua or tepelcua, is a species of limbless amphibian in the family Dermophiidae. The species is native to Mexico and Central America, where it burrows under leaf litter and plant debris. Description The adult Mexican burrowing caecilian grows to a length of . In general appearance, it resembles a large earthworm. Around a hundred transverse annular folds in the skin give the appearance of segments. The head has a pointed snout, a single row of teeth in the lower jaw, and two vestigial eyes covered with skin, with a pair of protrusible tentacles between the eyes and the nostrils. The body is elongated and there are no limbs. The upper surface is dark grey and the under surface pale grey with darker markings on the annuli.

Caecilian
Caecilians (; ) are a group of limbless, vermiform or serpentine amphibians. They mostly live hidden in the ground and in stream substrates, making them the least familiar order of amphibians. Caecilians are mostly distributed in the tropics of South and Central America, Africa, and southern Asia. Their diet consists of small subterranean creatures such as earthworms. All modern caecilians and their closest fossil relatives are grouped as a clade, Apoda , within the larger group Gymnophiona , which also includes more primitive extinct caecilian-like amphibians. The name derives from the Greek words γυμνος (''gymnos'', naked) and οφις (''ophis'', snake), as the caecilians were originally thought to be related to snakes. The body is cylindrical dark brown or bluish black in colour. The skin is slimy and bears grooves or ringlike markings. Description Caecilians completely lack limbs, making the smaller species resemble worms, while the larger species, with lengths up ...
