The skin colour of amphibians is produced by three layers of pigment cells called chromatophores. These three cell layers consist of the melanophores (occupying the deepest layer), the guanophores (forming an intermediate layer and containing many granules, producing a blue-green colour) and the lipophores (yellow, the most superficial layer).
The skin is slimy and bears ringlike markings or grooves and may contain scales. [2] Modern caecilians are a clade, the order Gymnophiona / ˌ dʒ ɪ m n ə ˈ f aɪ ə n ə / (or Apoda / ˈ æ p ə d ə /), one of the three living amphibian groups alongside Anura and Urodela (salamanders).

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 ...
Adults range from 22 to 35 mm (0.9–1.4 inches) in body length; females usually attain larger sizes than males and exceed a little over 1.25 inches. Adult males are at an inch or less in length. [3] A male can be distinguished from a female during breeding season due to the visibility of a dark-pigmented vocal sac on his throat.
Amphibians are in decline worldwide, with 2 out of every 5 species threatened by extinction, according to a paper published Wednesday in the scientific journal Nature. More than 2,000 species of ...
Cutaneous respiration, or cutaneous gas exchange (sometimes called skin breathing), [1] is a form of respiration in which gas exchange occurs across the skin or outer integument of an organism rather than gills or lungs. Cutaneous respiration may be the sole method of gas exchange, or may accompany other forms, such as ventilation.
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.
