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.[2] Fire salamanders can have a very long lifespan; one specimen lived for more than 50 years in Museum Koenig, a German natural history museum.

Habitat, behavior and diet

Fire salamanders live in central European forests and are more common in hilly areas. They prefer deciduous forests, since they like to hide in fallen leaves and around mossy tree trunks. They need small brooks or ponds with clean water 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. They are active in the evening and the night, but on rainy days they are active in daytime as well.[3]

The diet of the fire salamander consists of various insects, spiders, earthworms and slugs, but they also occasionally eat newts and young frogs. In captivity, they eat crickets, mealworms, waxworms and silkworm larvae. Small prey will be caught within the range of the vomerine teeth or by the posterior half of the tongue, to which the prey adheres. It weighs about 40 grams. The fire salamander can grow to be 15–25 centimetres (5.9–9.8 in) long.

Reproduction

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 grasps 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.

Toxicit

Samandarin structure

Salamanders may actively defend themselves once they are grasped by a predator. Besides various antipredator postures, S. salamandra adults are able to exude toxic skin secretions such as 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 coloured portions of the animal's skin usually coincide with these glands. Compounds in the skin secretions may be effective against bacterial and fungal infections of the epidermis; some are potentially dangerous to human life.

Fire Salamanders are found in most of southern and central Europe. They are most commonly found at altitudes between 250 metres (820 ft) and 1,000 metres (3,300 ft), only rarely below (in Northern Germany sporadically down to 25 metres (82 ft)). However in the Balkans or Spain they are commonly found in higher altitudes as well
