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 fire salamander's primary alkaloid toxin, samandarin, causes strong muscle convulsions and hypertension combined with hyperventilation in all vertebrates. Through an analysis of the European fire salamander’s skin secretions, scientists have determined that another alkaloid, such as samandarone, is also released by the salamander. [14]

Although salamanders and newts seem to be the most susceptible, some anuran species are also affected. Bsal has emerged recently and poses a major threat to species in Europe and North America. It was described in 2013 based on a strain collected from skin tissue of fire salamanders Salamandra salamandra. The pathogen, unidentified up to then ...
Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves.
A mental gland is a part of the body found in many species of amphibians and reptiles. Mental glands produce chemicals that conspecific animals use to communicate . [ 1 ] [ 2 ]
The Corsican fire salamander (Salamandra corsica) is a species of salamander in the family Salamandridae found only on the island of Corsica as an endemic species. In former times, this species was known as a subspecies of the widespread but continental-distributed fire salamander , which may appear quite similar.
