Dermophis Glandulosus
''Dermophis glandulosus'' is a species of caecilian in the family Dermophiidae. It is found in northwestern Colombia ( Córdoba and Antioquia Departments), Costa Rica, and Panama. It is the southernmost species among ''Dermophis''. Description ''Dermophis glandulosus'' is a moderately large caecilian, measuring up to in total length. The type specimen was a juvenile measuring 159 mm. Also subsequent specimens were relatively small, leading to a conclusion that it was synonymous with '' Dermophis parviceps''. However, new specimens have shown ''Dermophis glandulosus'' to be a separate, much larger species than ''Dermophis parviceps''. It also lacks the contrasting head coloration of the latter and has more secondary annuli. The dorsum is purplish lavender, whereas the ventral surfaces are dull cream with dim lavender clouding. Habitat and conservation ''Dermophis glandulosus'' occurs in humid montane and lowland forests. In Colombia it occurs at elevations of above sea le ...

Dermophis Oaxacae
''Dermophis oaxacae'', also known Oaxacan caecilian, is a species of caecilian in the family Dermophiidae. It is endemic to southwestern Mexico and occurs on the Pacific slopes and the Balsas depression in the states of Jalisco, Michoacán, Guerrero, Oaxaca, and Chiapas. Description ''Dermophis oaxacae'' is a relatively large caecilian with a reported maximum total length of . It has 119–139 primary and 101–133 secondary annuli; these high counts distinguish it from all other ''Dermophis''. The body is somewhat robust and the head is relatively large.

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. Distribution and habitat The Mexican burrowing caecilian is found in Mexico, Guatemala, El Salvador, Honduras, Nicaragua, and possib ...

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 In animals, viviparity is development of the embryo inside the body of the mother, with the maternal circulation providing for the ...

Dermophis Costaricense
''Dermophis costaricense'' is a species of caecilian in the family Dermophiidae. It is endemic to Costa Rica and is found on the Atlantic versant of Cordillera de Tilarán, Cordillera Central, and Cordillera de Talamanca. Its taxonomic status is in need of a review. Description ''Dermophis costaricense'' is a moderate-sized species: total length is . It is characterized by high numbers of both primary (107–117) and secondary annuli (74–96). The annuli are not darkly demarcated ventrally, as seen in ''Dermophis mexicanus'', which is also a larger species. ''D. costaricense'' appears to be closely related with '' Dermophis gracilior'' from the Pacific versant of Costa Rica, and it is possible that these two species turn out to be the same species. However, as presently known, their ranges do not overlap and they can be distinguished based on the total number of annuli (higher in ''D. costaricense''). Habitat and conservation ''Dermophis costaricense'' occurs in premontane rain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dermophis Gracilior
''Dermophis gracilior'' is a species of caecilian in the family Dermophiidae. It is found on the Pacific slopes of Cordillera de Talamanca in eastern Costa Rica and western Panama, as well as in the central Pacific Costa Rica. Some sources also report it from the Atlantic slope of Costa Rica. Description ''Dermophis gracilior'' is a moderate-sized caecilian measuring in total length. It has 91–117 primary and 65–96 secondary annuli. The body is somewhat robust (length 23 to 34 times the body width). The upper surface is lead-gray in color, whereas the lower one is cream with dark mottling, or largely gray to dull black. The annular grooves are similarly colored as the adjacent areas. Habitat and conservation ''Dermophis gracilior'' occurs in humid lowland, premontane, and montane forests at elevations above sea level. It is a subterranean species that can be found under logs and surface debris. It is probably viviparous. ''D. gracilior'' is a poorly known species known f ...

Dermophiidae
The Dermophiidae are a family of neotropical caecilians. They are found in Central and South America, and Africa. Like other caecilians, they superficially resemble worms or snakes. They are the only viviparous caecilians (species that give birth to live young) with secondary annuli (rings around the body).

Amphibian
Amphibians are ectothermic, anamniote, anamniotic, tetrapod, four-limbed vertebrate animals that constitute the class (biology), class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all Tetrapod, tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant taxon, extant (living) amphibians belong to the monophyletic subclass (biology), subclass Lissamphibia, with three living order (biology), orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater ecosystem, freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats).
