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. Taxonomy The 14 species in three genera are: * Genus '' Amazops'' ** ''Amazops amazops'' (Ecuador) * Genus ''Epicrionops'' ** ''Epicrionops bicolor'' (Peru, Ecuador, Venezuela, and Colombia) ** ''Epicrionops columbianus'' (Colombia) ** '' Epicrionops lativittatus'' (Peru) ** ''Epicrionops marmoratus'' (Ecuador) ** '' Epicrionops parkeri'' (Colombia) ** '' Epicrionops peruvianu ...

Rhinatrema Gilbertogili
''Rhinatrema'' is a genus of caecilians in the family 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 basa .... Their common name is two-lined caecilians. The genus is known from the Guyanas (Guyana, French Guiana, and Suriname) and adjacent Brazil. 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 monotypic, only species in the genus ''Rhinatrema''. However, in 2010 and 2018, new species were described. The genus now contains now six species: References Rhinatrematidae Amphibians of Brazil Amphibians of French Guiana Amp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 caecil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

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.
