Selected amphibian type

Spotted salamander, Ambystoma maculatum

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. (Full article...)

Distribution of A. ruthveni (in black)

The Tukeit Hill frogs are three species of frog in the genus Allophryne. Originally erected for the species Allophryne ruthveni, the genus was placed as the only member of the subfamily Allophryninae, which was in turn placed in the family Centrolenidae, but they are now considered as the only genus in the monotypic family Allophrynidae.

These frogs live in Guyana, Venezuela, Suriname, Brazil and Bolivia. The holotype was discovered at Tukeit Hill, below Kaieteur Falls, Guyana, hence the common English name. (Full article...)

Selected caecilian article

Typhlonectes natans

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 100 cm (39 in) in length, but other species in the family range from 20 to 60 cm (7.9–23.6 in). A sixth typhlonectid genus, Ymboirana, was recently described and is known exclusively from fossil material. (Full article...)
