This list of Anuran families shows all extant families of Anura. Anura is an order of animals in the class Amphibia that includes frogs and toads. More than 5,000 species are described in the order. The living anurans are typically divided into three suborders: Archaeobatrachia, Mesobatrachia, and Neobatrachia. This classification is based on ...
Depending on the species, male or female toads may possess a Bidder's organ, a trait unique to all bufonids except genera Melanophryniscus and Truebella. [8] Under the right conditions, the organ becomes an active ovary. [9] The loss of teeth has arisen in frogs independently over 20 times. Notably, all members of Bufonidae are toothless.
The Anura include all modern frogs and any fossil species that fit within the anuran definition. The characteristics of anuran adults include: 9 or fewer presacral vertebrae, the presence of a urostyle formed of fused vertebrae, no tail, a long and forward-sloping ilium, shorter fore limbs than hind limbs, radius and ulna fused, tibia and ...
This suborder is the most advanced and apomorphic of the three anuran suborders alive today, hence its name, which literally means "new frogs" (from the hellenic words neo, meaning "new" and batrachia, meaning "frogs"). It is also by far the largest of the three; its more than 5,000 different species make up over 96% of all living anurans.
List of Anuran families Toad is a common name for certain frogs , especially of the family Bufonidae , that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands .
Hyloidea accounts for 54% of all living anuran species. [2] The superfamily Hyloidea branched off from its closest relative, the Australobatrachia , during the mid- Cretaceous . [ 3 ] The fossil evidence found during the Cretaceous-Paleogene extinction event could not determine the effects upon the frogs, due to the lack of fossils.
Like other species in the genus Chiromantis, they have discs on their toes, and their outer two fingers are widely spaced and nearly at a right angle to their inner two fingers on each hand. The grey foam-nest tree frog typically has a snout length of 50–80 mm. Males have a snout-vent length of 43–75 mm, while females have a 60–90 mm ...
The Salientia (Latin salire, salio meaning "to jump") are a total group of amphibians that includes the order Anura, the frogs and toads, and various extinct proto-frogs that are more closely related to the frogs than they are to the Urodela, the salamanders and newts. [1]
