Rhinatrematidae
Rhinatrematidae is a family of caecilians, also known as the Neotropical tailed caecilians, American tailed caecilians. or beaked caecilians. They are found in the equatorial countries of South America. They are usually regarded as the most basal of the caecilian families, with numerous characteristics lacking in the other groups. For example, they still possess tails, and their mouths are not recessed on the underside of their heads. They lay their eggs in cavities in the soil. The larvae have external gills, and live in seepage areas until they metamorphose. The adults live in moist soil and leaf litter Plant litter (also leaf litter, tree litter, soil litter, litterfall, or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that has fallen to the ground. This detritus or dead organic material and its constituen .... Taxonomy The 14 species in three genera are: * Genus '' Amazops'' ** '' Amazops amazops'' (Ecuador) * Genus '' Epicrionops'' * ...

Rhinatrema
''Rhinatrema'' is a genus of caecilians in the family Rhinatrematidae. Their common name is two-lined caecilians. The genus is known from the Guyanas (Guyana, French Guiana, and Suriname) and adjacent Brazil Brazil, officially the Federative Republic of Brazil, is the largest country in South America. It is the world's List of countries and dependencies by area, fifth-largest country by area and the List of countries and dependencies by population .... Most ''Rhinatrema'' are known to inhabit and live in areas of tropical forests where there is an abundance of dense, dead vegetation matter. ''Rhinatrema'' are primitive caecilians that have a true tail. They are oviparous. Until recently, the two-lined caecilian (''R. bivittatum'') was the only species in the genus ''Rhinatrema''. However, in 2010 and 2018, new species were described. The genus now contains now six species: References Rhinatrematidae Caecilians of Brazil Amphibians of French Guiana Amphibians o ...

Amazops
''Amazops'' is a monotypic genus of caecilian in the family Rhinatrematidae. It contains only one species, ''Amazops amazops''. It is endemic to Ecuador and is only known from a single specimen collected around 1990 from the Virgen La Dolores Farm in the province of Orellana. The individual was found in very soft, red and muddy soil under some rocks on a dirt road in a portion of the Ecuadorian Amazon at an altitude of about 1000 meters above sea level. It is presumed that like most other rhinatrematids, it is oviparous and is aquatic during its larval phase. It is the first new species of rhinatrematid caecilian from the Andes described after more than 50 years, and can be distinguished from other members of the family by its elongated squamous bone that is a part of the eye's orbit and occupies anterior parts of the skull, parts that are normally occupied by the maxilla and palatine in other rhinatrematids. It shares these anatomical traits with other non-rhinatrematid caeci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caecilian
Caecilians (; ) are a group of limbless, vermiform (worm-shaped) or serpentine (snake-shaped) amphibians with small or sometimes nonexistent eyes. They mostly live hidden in soil or in streambeds, and this cryptic lifestyle renders caecilians among the least familiar amphibians. Modern caecilians live in the tropics of South America, South and Central America, Africa, and southern Asia. Caecilians feed on small subterranean creatures, such as earthworms. The body is cylindrical and often darkly coloured, and the skull is bullet-shaped and strongly built. Caecilian heads have several unique adaptations, including fused cranial and jaw bones, a two-part system of jaw muscles, and a Chemoreceptor, chemosensory tentacle in front of the eye. The skin is slimy and bears ringlike markings or grooves and may contain scales. Modern caecilians are a clade, the Order (biology), order Gymnophiona (or Apoda ), one of the three living amphibian groups alongside Anura (frogs) and Urodela (sa ...

Rhinatrema Nigrum
''Rhinatrema nigrum'', the black caecilian, is a species of caecilian in the family Rhinatrematidae found in Guyana, Venezuela, and possibly Brazil. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, rivers, and intermittent rivers. Taxonomy This species was first described by the American herpetologist Emmett Reid Dunn in 1942 as ''Rhinatrema nigrum'', the type locality being Arundabara, British Guiana. It has been included in the genus '' Epicrionops'' as ''Epicrionops niger''. Dunn, E.R. 1942. The American caecilians. ''Bulletin of the Museum of Comparative Zoology'' 91: 437–540. Distribution and habitat The black caecilian is native to south eastern Venezuela and western Guyana, and possibly northern Brazil. It occurs at altitudes of between in moist lowland and montane forests, cloud forests, seasonally dry forests, wetlands, marshes and the banks of temporary and permanent water courses.
