The world's largest frog is the goliath frog of West Africa—it can grow to 15 inches (38 centimeters) and weigh up to 7 pounds (3.2 kilograms). One of the smallest is the Cuban tree toad, which ...
Some 50 to 100 extant species are now placed in this genus by various authors; many other species formerly placed in Rana are now placed elsewhere. Frost [3] restricted Rana to the Old World true frogs and the Eurasian brown and pond frogs of the common frog R. temporaria group, [4] although other authors disagreed with this arrangement.
The list below largely follows Darrel Frost's Amphibian Species of the World (ASW), Version 5.5 (31 January 2011). Another classification, which largely follows Frost, but deviates from it in part is the one of AmphibiaWeb , which is run by the California Academy of Sciences and several of universities.
Brevicipitidae or rain frogs is a small family of frogs found in eastern and southern Africa.As of 2020 contains 37 species in 5 genera. [1] [2] Formerly included as subfamily in Microhylidae (narrow-mouth frogs), phylogenetic research has indicated the brevicipitine frogs should be considered as a family with Hemisotidae (shovelnose frogs) as the most closely related sister taxon.
True frogs is the common name for the frog family Ranidae. They have the widest distribution of any frog family. They are abundant throughout most of the world, occurring on all continents except Antarctica. The true frogs are present in North America, northern South America, Europe, Africa (including Madagascar), and Asia.
The Guinness Book of World Records lists the frog's body weight at 10 milligrams (0.00035 oz), [13] while measurements of Schindleria brevipinguis show them to weigh less than 2 milligrams (7.1 × 10 −5 oz), with one adult specimen weighing just 0.7 milligrams. [14] The frog lives on land and its life cycle does not include a tadpole stage. [11]
The goliath frog (Conraua goliath), otherwise known commonly as the giant slippery frog and the goliath bullfrog, is a species of frog in the family Conrauidae. The goliath frog is the largest living frog. [3] [4] Specimens can reach up to about 35 centimetres (14 in) in snout–vent length and 3.3 kilograms (7.3 lb) in weight. [5]
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. More than 5,000 species are described in the order. The living anurans are typically divided into three suborders: Archaeobatrachia , Mesobatrachia , and Neobatrachia .
