The first is somewhat toad-like and can often be found on land. The second is smoother and more frog-like, preferring the water. [7] The third genus was until recently considered extinct, and is represented by the recently rediscovered Hula painted frog. All of the species have pond-dwelling tadpoles.
This frog lives in fast-flowing streams and internal fertilisation prevents the sperm from being washed away before fertilisation occurs. [90] The sperm may be retained in storage tubes attached to the oviduct until the following spring. [91] Most frogs can be classified as either prolonged or explosive breeders.
The archaeobatrachians are the most primitive of frogs. These frogs have morphological characteristics which are found mostly in extinct frogs, and are absent in most of the modern frog species. Most of these characteristics are not common between all the families of Archaeobatrachia, or are not absent from all the modern species of frogs.
The oldest fossil "proto-frog" Triadobatrachus is known from the Early Triassic of Madagascar (250 million years ago), but molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest ...

A true toad is any member of the family Bufonidae, in the order Anura (frogs and toads). This is the only family of anurans in which all members are known as toads, although some may be called frogs (such as harlequin frogs). The bufonids now comprise more than 35 genera, Bufo being the best known.
A birth chart, also known as your natal chart, is a “snapshot of where all the planets were in their orbit the moment you were born,” Edut says. “The birth chart tells a story: your life ...
The Batrachia / b ə ˈ t r eɪ k i ə / are a clade of amphibians that includes frogs and salamanders, but not caecilians nor the extinct allocaudates. [1] The name Batrachia was first used by French zoologist Pierre André Latreille in 1800 to refer to frogs, but has more recently been defined in a phylogenetic sense as a node-based taxon that includes the last common ancestor of frogs and ...
