The skin also has numerous ring-shaped folds, or annuli, that partially encircle the body, giving them a segmented appearance. Like some other living amphibians, the skin contains glands that secrete a toxin to deter predators. [15] The skin secretions of Siphonops paulensis have been shown to have hemolytic properties. [26]
On land, amphibians are restricted to moist habitats because of the need to keep their skin damp. [31] Modern amphibians have a simplified anatomy compared to their ancestors due to paedomorphosis, caused by two evolutionary trends: miniaturization and an unusually large genome, which result in a slower growth and development rate compared to ...
The majority of amphibians use cutaneous respiration, or the process of breathing through the skin. Due to the importance of the skin, amphibians are very sensitive to what goes through their permeable skin, the stratum corneum is the main skin barrier which is much thinner than other classes such as mammals or birds.
The Brothers Grimm fairy tale The Frog Prince features a princess taking in a frog and it turning into a handsome prince. [236] In modern culture, frogs may take a comedic or hapless role, such as Mr. Toad of the 1908 novel The Wind in the Willows, Michigan J. Frog of Warner Bros. Cartoons, the Muppet Kermit the Frog and in the game Frogger. [237]
The skin of salamanders, in common with other amphibians, is thin, permeable to water, serves as a respiratory membrane, and is well-supplied with glands. It has highly cornified outer layers, renewed periodically through a skin shedding process controlled by hormones from the pituitary and thyroid glands. During moulting, the skin initially ...

The Lissamphibia (from Greek λισσός (lissós, "smooth") + ἀμφίβια (amphíbia), meaning "smooth amphibians") is a group of tetrapods that includes all modern amphibians. Lissamphibians consist of three living groups: the Salientia ( frogs and their extinct relatives), the Caudata ( salamanders and their extinct relatives), and the ...
Amphisbaenia / æ m f ɪ s ˈ b iː n i ə / (called amphisbaenians or worm lizards) is a group of typically legless lizards, [2] comprising over 200 extant species. Amphisbaenians are characterized by their long bodies, the reduction or loss of the limbs, and rudimentary eyes.
