The fire salamander (Salamandra salamandra) is a common species of salamander found in Europe. It is black with yellow spots or stripes to a varying degree; some specimens can be nearly completely black while on others the yellow is dominant.
Samandarines are exclusively produced and secreted by the fire salamander through their parotoid glands (20 mg/gland). Samandarin is the main component of these glandular secretions, although the precise ratio of the alkaloids can vary from species to species and individual to individual. [5]
The parotoid gland (alternatively, paratoid gland) is an external skin gland on the back, neck, and shoulder of some frogs (especially toads), and salamanders. It can secrete a number of milky alkaloid substances (depending on the species) known collectively as bufotoxins , which act as neurotoxins to deter predation .

The Mexican salamander matures undergoes a process called neoteny, which means the animal matures without going through metamorphosis. While most tadpoles eventually get to walk on the land, the ...
