Conraua, known as slippery frogs or giant frogs is a genus of large frogs from sub-Saharan Africa. [2] Conraua is the only genus in the family Conrauidae. [3] [4] Alternatively, it may be placed in the family Petropedetidae.
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]
Attenborough handles a goliath frog, the largest of the species, to demonstrate its characteristics. Their webbed feet form parachutes that turn them into "dazzling athletes", and some can leap over 15 metres—100 times their body length. In addition, their vocal sacs ensure that mating calls can be heard from up to a mile away.
The largest frog is the African Goliath frog (Conraua goliath), which can reach 32 cm (13 in) and weigh 3 kg (6.6 lb). [41] Amphibians are ectothermic (cold-blooded) vertebrates that do not maintain their body temperature through internal physiological processes.
Frogs range in size from Paedophryne amauensis of Papua New Guinea that is 7.7 mm (0.30 in) in snout–vent length [48] to the up to about 35 cm (14 in) and 3.3 kg (7.3 lb) goliath frog (Conraua goliath) of central Africa. [49] There are prehistoric, extinct species that reached even larger sizes. [50]
The Secret Life of Frogs is a 2019 Indian documentary film that explores lesser-known frog species. It premiered on May 1, 2019, on Animal Planet. [1] Directed by Ajay Bedi, Vijay Bedi, and narrated by Jeff Alan Greenway, [2] the 45-minute film provides insights into the behaviors and lives of various frog species, with a particular focus on the purple frog and the torrent frog.
The African bullfrog males call out during the rainy season. The call lasts about a second and can be described as a low-pitched whoop. [16] Males have two breeding strategies, depending on their age. Young males congregate in a small area, perhaps only 1–2 m 2 (11–22 sq ft) of shallow water.
Frogs produce a wide range of vocalisations, particularly in their breeding season, and exhibit many different kinds of complex behaviors to attract mates, to fend off predators and to generally survive. (Full article...
