Amphibians use their skin as a secondary respiratory interface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards , but unlike reptiles and other amniotes , require access to water bodies to breed.

Four-stroke buccal pumping is used by some basal ray-finned fish and aquatic amphibians such as Xenopus and Amphiuma. [1] This method has several stages. These will be described for an animal starting with lungs in a deflated state: First, the glottis (opening to the lungs) is closed, and the nostrils are opened. The floor of the mouth is then ...

Both the lungs and the skin serve as respiratory organs in amphibians. The ventilation of the lungs in amphibians relies on positive pressure ventilation. Muscles lower the floor of the oral cavity, enlarging it and drawing in air through the nostrils into the oral cavity. With the nostrils and mouth closed, the floor of the oral cavity is then ...
Their tails are short or absent, and their cloacae are near the ends of their bodies. [8] [9] [10] Except for one lungless species, Atretochoana eiselti, [11] all caecilians have lungs, but also use their skin or mouths for oxygen absorption. Often, the left lung is much smaller than the right one, an adaptation to body shape that is also found ...
Although it is common for amphibia to respire out of their skin, also known as cutaneous respiration, it was found that amphiuma primarily respire through their lungs, despite their aquatic lifestyle. [19] This is suggested by the high lung to respiratory capillary density compared to the relatively low skin to respiratory capillary density ...
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 ...
