Siphonops
''Siphonops'' is a genus of caecilians in the family Siphonopidae, found in South America. All species are known to occur within Brazil, however, only ''S. hardyi'' and ''S. leucoderus'' are endemic to it. The native ranges of the other two known species, ''S. annulatus'' and ''S. paulensis'', extend outwards into the surrounding countries of Argentina, Bolivia, and Paraguay. ''S. annulatuss range extends even further, stretching into Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela, and giving it perhaps the most widespread distribution of any single caecilian species. ''Siphonops'' contains the following four species: * ''Siphonops annulatus ''Siphonops annulatus'', the ringed caecilian, is a species of caecilian in the family Siphonopidae endemic to South America.

Siphonops Annulatus
''Siphonops annulatus'', the ringed caecilian, is a species of caecilian in the family Siphonopidae endemic to South America. It may have the broadest known distribution of any terrestrial caecilian species. Description Ringed caecilian measures in total length. The body is cylindrical and slightly wider than deep. It is bluish-black to slate in colour. The annular grooves that completely encircle the body (except the 3–4 posteriormost ones) are edged in white or cream. A team of scientists from Brazil and the United States discovered that these organisms have skin glands with different specialized functions. Glands on the head of the animals excrete lubricating mucus which may aid them in burrowing, while those on the tail region are packed with noxious chemicals, similar to the poison glands found in other amphibians such as toads and newts. Behavior Caecilians are some of the least studied amphibians. Not much is known about their behavior and life history. ''Siphonop ...

Cutuchi
''Siphonops paulensis'', or Boettger's caecilian, is a species of caecilian in the family Siphonopidae. It is found in northern Argentina, Paraguay, eastern Bolivia, and southern 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 .... It lives subterraneously in forests, savannas, shrublands, and grassland. It also adapts to anthropogenic disturbance and can even live in urban gardens. In fact these caecilians have even been recorded to breed and raise their young close to Santa Cruz, a highly populated city. It is a locally common species that is not facing major threats.

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 ...

Amphibian Genera
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 ...

Siphonops Leucoderus
''Siphonops leucoderus'', the Salvador caecilian, is a species of caecilian in the family Siphonopidae.
