Selected amphibian type

European fire-bellied toad (Bombina bombina), a member of the family Bombinatoridae

Bufonidae, that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands
.

In popular culture (folk taxonomy), toads are distinguished from frogs by their drier, rougher skin and association with more terrestrial habitats. However, this distinction does not align precisely with scientific taxonomy. (Full article...)

Selected frog article

The tailed frogs are two species of frogs in the genus Ascaphus, the only taxon in the family Ascaphidae /æˈskæfɪdiː/. The "tail" in the name is actually an extension of the male cloaca. The tail is one of two distinctive anatomical features adapting the species to life in fast-flowing streams. These are the only North American frog species that reproduce by internal fertilization. They are among the most primitive known families of frogs.

Its scientific name means 'without a spade', from the privative prefix

metatarsal spade, which these frogs do not have. (Full article...

Selected salamander article

Karaurus sharovi a non-urodelan caudatan from the Middle-Late Jurassic belonging to the family Karauridae

The Caudata are a group of amphibians containing the extant salamanders (the order Urodela) and all extinct species of amphibians more closely related to salamanders than to frogs. They are typically characterized by a superficially 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.

Disagreement exists between different authorities as to the definition of the terms "Caudata" and "Urodela". Some maintain that Urodela should be restricted to the

total group. Others restrict the name Caudata to the crown group and use Urodela for the total group. The former approach seems to be most widely adopted and is used in this article. (Full article...

It is currently classified as an Endangered species on the IUCN Red List of Threatened Species because of habitat destruction. The arroyo toad is at the intersection of ecological significance and conservation concern. (Full article...

Selected caecilian article

Siphonops annulatus

Caeciliidae is the family of common caecilians. They are found in Central and South America. Like other caecilians, they superficially resemble worms or snakes.

Although they are the most diverse of the caecilian families, the caeciliids do have a number of features in common that distinguish them from other caecilians. In particular, their skulls have relatively few bones, with those that are present being fused to form a solid ram to aid in burrowing through the soil. The mouth is recessed beneath the snout, and there is no tail.

Many caeciliids lay their eggs in moist soil. The eggs then hatch into aquatic larvae, which live in seepages in the soil, or in small streams. However, some species lack a larval stage, with the eggs hatching into juveniles with the same form as the adults, or else lack eggs and give birth to live young. (Full article...)
