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 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]

The salamander's skin has a granular to smooth texture, with small dome-shaped protuberances along the head. Their dorsum can range from tan brown to green, sometimes with dark brown spots, while their undersides are a pale grey. Their toes, rostrum of the head, cloaca, and underside of the tail tend to have a darker coloring compared to the body.
