Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela from the group Caudata. Urodela is a scientific Latin term based on the Ancient Greek οὐρά δήλη: ourà dēlē "conspicuous tail". Caudata is the Latin for "tailed ones", from cauda : "tail".
Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm. Salamanders never have more than four toes on their front legs and five on their rear legs, but some species have fewer digits and others lack hind limbs. Their permeable skin usually makes them reliant on habitats in or near water or other cool, damp places. Some salamander species are fully aquatic throughout their lives, some take to the water intermittently, and others are entirely terrestrial as adults.
This group of amphibians is capable of regenerating lost limbs as well as other damaged parts of their bodies. Researchers hope to reverse engineer the regenerative processes for potential human medical applications, such as brain and spinal cord injury treatment or preventing harmful scarring during heart surgery recovery. The remarkable ability of salamanders to regenerate is not just limited to limbs but extends to vital organs such as the heart, jaw, and parts of the spinal cord, showing their uniqueness compared to different types of vertebrates. This ability is most remarkable for occurring without any type of scarring. This has made salamanders an invaluable model organism in scientific research aimed at understanding and achieving regenerative processes for medical advancements in human and animal biology.

Sooglossidae, the Seychelles frogs or Seychelles Island frogs, are a family of frogs found on the Seychelles Islands. Until recently, this family was believed to include the genera Sechellophryne, Nesomantis and Sooglossus, but following a major revision of amphibians in 2006, the genus Nesomantis was named a junior synonym of Sooglossus. Their closest relatives are the purple frogs ( Nasikabatrachidae) of India. ( Full article...)

Truebella is a genus of small true toads, family Bufonidae. It is endemic to the Ayacucho and Junín Regions of Peru. The generic name honors Linda Trueb , an American herpetologist. ( Full article...)
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. annulatus's 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:
