The skin of amphibians is a major site of respiration in all species for which measurements are available. [2] Cutaneous respiration is the sole respiratory mode of lungless salamanders (family Plethodontidae) which lack lungs entirely yet constitute the largest family of salamanders. Cutaneous respiration in frogs and other amphibians may be ...
Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals).
An adult weighs 1.5 to 2.5 kg (3.3 to 5.5 lb), making them the fifth heaviest living amphibian in the world after their South China, Chinese and Japanese cousins and the goliath frog, while the largest cane toads may also weigh as much as a hellbender. Hellbenders reach sexual maturity at about five years of age, and may live 30 years in captivity.
Frog. This article is about the group of amphibians. For other uses, see Frog (disambiguation). A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura[1] (coming from the Ancient Greek ἀνούρα, literally 'without tail').
Buccal pumping. Buccal pumping is "breathing with one's cheeks": a method of ventilation used in respiration in which the animal moves the floor of its mouth in a rhythmic manner that is externally apparent. [1] It is the sole means of inflating the lungs in amphibians.
These frogs are suggested to be kept in a group of two or more due to their social nature. Despite being fully aquatic, the African dwarf frog still needs to be able to reach the surface to breathe. These amphibians are not great swimmers, so water currents should be kept low and deep tanks may pose a challenge to their ability to breathe.
Cloaca. A cloaca (/ kloʊˈeɪkə / ⓘ kloh-AY-kə), pl.: cloacae (/ kloʊˈeɪsi / kloh-AY-see or / kloʊˈeɪki / kloh-AY-kee), or vent, is the rear orifice that serves as the only opening for the digestive, reproductive, and urinary tracts (if present) of many vertebrate animals. All amphibians, reptiles, birds, and a few mammals ...
Tadpole. Common frog (Rana temporaria) tadpole. A tadpole or polliwog (also spelled pollywog) is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish -like features that may not be found in adult amphibians ...
