''Typhlonectes'' (from , 'blind' and , 'swimmer') is a genus of caecilians in the family Typhlonectidae. These fully aquatic amphibians are found in the Amazon Basin and Northern South America, and typically range between in length.Vitt, L.J.; and Caldwell, J.P. (2013).

Typhlonectes Natans
''Typhlonectes natans'', also correctly called the rubber eel or Rio Rauca caecilian, is a species of caecilian in the family (biology), family Typhlonectidae found in Colombia, Venezuela, and possibly Trinidad and Tobago. Its natural habitats are dry savanna, subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, subtropical or tropical seasonally wet or flooded lowland grassland, and rivers. ''T. natans'' is commonly kept as an aquarium pet, and is sometimes sold as a "fish" in aquarium stores. A specimen of ''T. natans'' was found in October 2019 in Miami-Dade County, Florida, Miami-Dade County, Florida, making it the first caecilian to be collected in North America. They grow to in length. They are dark grey to black in color. While ''T. natans'' can and occasionally does breathe air at the surface, most of its respiration takes place through its skin. The species is ovoviviparous, giving birth to young in water. The gestation period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhlonectes Compressicauda
''Typhlonectes compressicauda'', the Cayenne caecilian, is a species of amphibian in the family Typhlonectidae that lives in water. It is found in Amazon basin, Amazonian Brazil, Peru, and Colombia as well as in Guyana and French Guiana, and likely Suriname, and according to some sources, Venezuela. It is an aquatic caecilian that inhabits permanent rivers and marshes mainly in the lowland forest zone. Description The Cayenne caecilian is an elongated, dark grey, black or steely blue amphibian with no limbs. The body is flattened laterally and has a number of transverse folds, giving it a segmented appearance. A long fin runs along its back, and it grows to a length of . It has a more highly derived morphology than some more primitive species, showing differences in lung structure, the reproductive organs, and the kidneys. Distribution The Cayenne caecilian occurs in South America, including the Amazon basin and river systems in the Guianas. It is found at altitudes of up to abo ...

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 ...

Typhlonectidae
Typhlonectidae, also known as aquatic caecilians or rubber eels, are a family of caecilians found east of the Andes in South America. They are viviparous animals, giving birth to young that possess external gills. Of the five extant genera in the family, ''Atretochoana'', ''Potamotyphlus'' and ''Typhlonectes'' are entirely aquatic, while ''Chthonerpeton'' and ''Nectocaecilia'' are semi-aquatic. ''Atretochoana'' reaches in length, but other species in the family range from . A sixth typhlonectid genus, ''Ymboirana'', was recently described and is known exclusively from fossil material.

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). Their biological life cycle, life cycle typically starts out as aquatic animal, aquatic larvae with gills known as tadpoles, but some species have devel ...

Amazon Basin
The Amazon basin is the part of South America drained by the Amazon River and its tributary, tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela, as well as the territory of French Guiana. Most of the basin is covered by the Amazon rainforest, also known as Amazon rainforest, Amazonia. With a area of dense tropical forest, it is the largest rainforest in the world. Geography The Amazon River begins in the Andes, Andes Mountains at the west of the basin with its main tributary the Marañón River and Apurímac River, Apurimac River in Peru. The highest point in the Drainage divide, watershed of the Amazon is the second biggest peak of Yerupajá at . The Amazon River Basin occupies the entire central and eastern area of South America, lying to the east of the Andes mountain range and extending from th ...
