The numbers of species cited above follows Frost and the total number of known (living) amphibian species as of March 31, 2019, is exactly 8,000, [11] of which nearly 90% are frogs. [ 12 ] With the phylogenetic classification, the taxon Labyrinthodontia has been discarded as it is a polyparaphyletic group without unique defining features apart ...
List of amphibians. The temnospondyl Eryops had sturdy limbs to support its body on land. Red-eyed tree frog (Agalychnis callidryas) with limbs and feet specialised for climbing. Japanese giant salamander (Andrias japonicus), a primitive salamander. The bright colours of the common reed frog (Hyperolius viridiflavus) are typical of a toxic species.
Global biodiversity is the measure of biodiversity on planet Earth and is defined as the total variability of life forms. More than 99 percent of all species [ 1 ] that ever lived on Earth are estimated to be extinct. [ 2 ][ 3 ] Estimates on the number of Earth's current species range from 2 million to 1 trillion, but most estimates are around ...
About 10% of the species of the Earth can be found in Colombia, including over 1,900 species of bird, more than in Europe and North America combined, Colombia has 10% of the world's mammals species, 14% of the amphibian species and 18% of the bird species of the world. [100]
Amphibians are in decline worldwide, with 2 out of every 5 species threatened by extinction, according to a paper published Wednesday in the scientific journal Nature.
More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [8] [9] Estimates on the number of Earth's current species range from 10 million to 14 million, [10] of which about 1.2 million have been documented and over 86 percent have not yet been described.

In biology, a phylum (/ ˈfaɪləm /; pl.: phyla) is a level of classification or taxonomic rank below kingdom and above class. Traditionally, in botany the term division has been used instead of phylum, although the International Code of Nomenclature for algae, fungi, and plants accepts the terms as equivalent. [1][2][3] Depending on ...
AmphibiaWeb's goal is to provide a single page for every species of amphibian in the world so research scientists, citizen scientists and conservationists can collaborate. [1] It added its 7000th animal in 2012, a glass frog from Peru. [2] [3] As of 2022, it hosted more than 8,400 species located worldwide. [4] [5]
