Fire salamander (Salamandra salamandra)

This nocturnal animal has large black eyes. On its back, its  smooth black skin has a pattern of yellow (sometimes orange or red) points or lines. The pattern is different for each individual and makes it possible to identify them. The thick shiny skin has many glands, which secrete a fine layer of mucus containing a neurotoxin that acts when it comes into contact with mucous membranes. These secretions primarily serve to suppress the growth of bacterial and fungal infections on the animal's moist skin (bactericidal and fungicidal properties).
