The Fire Salamander (Salamandra salamandra) is probably the best-known salamander species 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. Shades of red and orange may sometimes appear, either replacing or mixing with the yellow according to subspecies. Fire Salamanders can have a very long lifespan. A salamander lived for more than 50 years in Museum Koenig, a German natural history museum.

Fire Salamanders live in forests in the hilly parts of southern and central Europe. They prefer deciduous forests, as they like to hide in the fallen leaves, but also at mossy tree trunks. They need clean small brooks in their habitat for the development of the larvae. Whether on land or in water, fire salamanders are inconspicuous. They spend much of their time hidden beneath stones, wood or other objects.
Fire Salamanders are active in the evening and the night, but on rainy days they are active in daytime as well. Their diet consists of various insects, spiders, earthworms and slugs, but they also occasionally eat small vertebrates like newts and young frogs. Small prey will be caught within the range of the vomerine teeth or by the posterior half of the tongue, which adheres the prey. The fire salamander can grow to around 8 inches.
It is possible that the name of the species derives from old tales of these amphibians: the salamanders hide within holes and crevasses in damp wood and tree trunks. When humans cut down wood to use for heating, the salamanders often remained hidden within. When a fire was lit, the heat forced the animals to leave the wood and crawl to safety, because of this they appear as though they were "crawling from within the flames".
Males and females look very similar except during the breeding season, when the most conspicuous difference is a swollen gland around the male's vent. This gland produces the spermatophore, which carries a sperm packet at its tip. The courtship happens on land. After the male becomes aware of a potential mate, he confronts her and blocks her path. The male rubs her with his chin to express his interest in mating, then crawls beneath her and graps her front limbs with his own in amplexus. He deposits a spermatophore on the ground, then attempts to lower the female's cloaca into contact with it. If successful, the female draws the sperm packet in and her eggs are fertilized internally. The eggs develop internally and the female deposits the larvae into a body of water just as they hatch. In some subspecies the larvae continue to develop within the female until she gives birth to fully formed metamorphs. Breeding has not been observed in neotenic fire salamanders.
Salamanders may actively defend themselves once they are grasped by a predator. Besides various antipredator postures, S. salamandra adults are able to extrude heavy toxic skin secretions, e.g. the neurotoxic alkaloid Samandarin. This alkaloid causes strong muscle convulsions and hypertension combined with hyperventilation in all vertebrates. The poison glands of the Fire Salamander are concentrated in certain areas of the body, especially around the head and the dorsal skin surface. The colored portions of the animal's skin usually coincide with these glands. Most of these secretions might be effective against bacterial and fungal infections of the epidermis, but some secretions could also be dangerous to human life.
Fire Salamanders are found in most of southern and central Europe. They are most commonly found at altitudes between 400 and 1000 m, only rarely below (in Northern Germany sporadically down to 25 m). However on the Balkan or in Spain they are commonly found in higher altitudes as well.

Several subspecies of the Fire Salamander are recognized. Most notable are the subspecies fastuosa and bernadezi, which are the only viviparous subspecies - the others are ovoviviparous.

The Fire Salamander (Salamandra salamandra) is probably the most well-known salamander species in Europe. It is black and has different kinds of yellow spots or stripes. Some salamanders are mostly black while others are mostly yellow. Shades of red and orange may sometimes appear. They either mix with the yellow, or replace it completely. This depends on the subspecies. Fire Salamanders can have a very long life. In the German natural history museum of Alexander Koenig a salamander lived more than 50 years.

Fire Salamanders live in forests in the hilly parts of southern and central Europe. They prefer deciduous forests. They like to hide in the fallen leaves or mossy tree trunks. They need clean small brooks (small rivers) in their habitat. This is for the development of the larvae. Both on land and in the water, Fire salamanders are hard to notice. They spend much of the time hidden beneath stones, wood or other objects.
Fire Salamanders are active in the evening and the night, but on rainy days they may be active in daytime as well. Their diet consists of insects, spiders, earthworms and slugs. Sometimes, they will eat small vertebrates--for example, newts and young frogs. Small prey will be caught within the range of the vomerine teeth or by the posterior half of the tongue, which sticks to the prey.
Males and females look pretty similar except during the breeding season, when the most conspicuous difference is a swollen gland around the male's vent. This gland produces the spermatophore, which carries a sperm packet at its tip. The courtship happens on land. After the male becomes aware of a potential mate, he confronts her and blocks her path. The male deposits his spermatophore on the ground. Reproduction occurs by means of this spermatophore, which will be taken up by the female. Their gills develop lungs. Neotenic fire salamanders have not been observed.
[[File:|thumb|Samandarin structure.]] Salamanders may actively defend themselves once they are grasped by a predator. Besides various antipredator postures, S. salamandra adults are able to make heavy poisons. These usually act on the nerves of the predator. They are called neurotoxins. One such poison is the alkaloid Samandarin. When the salamander senses danger, it can secrete this through its skin. This alkaloid causes strong muscle convulsions and high-blood pressure combined with hyperventilation in all vertebrates. The poison glands of the Fire salamander are concentrated in certain areas of the body, especially around the head and the dorsal skin surface. The colored portions of the animals skin usually coincide with these glands. Most of these secretions might be effective against bacterial and fungal infections of the epidermis, but some secretions could also be dangerous to human life.
