Here is what is unique about this salamander's offspring: The young develop and go through metamorphosis inside the mother's body and are born alive as tiny fully formed salamanders. Most salamanders lay eggs that hatch into larvae and undergo metamorphosis outside the female's body.

Salamandra atra
Laurenti, 1768
The Alpine Salamander (Salamandra atra) is a shiny black salamander. It is found in the Central and Eastern Alps, at altitudes above 700Â metres. Adult Alpine Salamanders are approximately 9 to 14Â cm in length. Their life expectancy is at least ten years.
It is an ovoviviparous amphibian, giving birth to two live young. Generally, at altitudes of 650-1,000Â metres, a pregnancy lasts 2 years, and at altitudes of 1,400 to 1,700Â metres, the pregnancy lasts 3 years.
The Black alpine salamander inhabits the region of the European Alps and other mountain regions between 800 m and 3000 m above the sea level. They prefer cool and humid places; however they are not depended on water. Their skin is moist with characteristic black and yellow stripes. His length is up to 15 cm and weights about 15 grams.
Salamandra atra is a nocturnal tailed amphibian and most of the day he spends in a shadow. He is sexually mature when reaching the age of 2 years. Salamander female lays eggs and then larval and adult stage follow. The Alpine salamander usually gives birth up to 4 young although much more eggs are fertilised.
The explanation is very simple: even small embryos feed themselves also with other developing eggs, which means they are cannibals already in the mother’s body, in uterus. After birth their diet consists of beetles, earthworms, spiders.
these are off the internet hope they help! =P

The spotted Salamandra maculosa, inhabited the lowlands and gave birth to ten to fifty larvae in water.
By switching the environments, it becomes apparant that depending on the ALTITUDE that these creatures live at, and the TEMPERATURE, the higher the altitude and lower the temperature, the fewer the births. The lower the altitude and the warmer the temerature the more births.
In the higher altitudes, they tend to give birth to fully-formed near adult salamaders.
In the lower altitudes, they tend to give birth to larve or tadpoles that eventually evolve into salamanders.

According to Wikkipedia this salamander "is an ovoviviparous amphibian." As I understand it it gives birth to living offspring. It can be pregnant up to two or three years dependent upon the altitude it is living at.
Hope that helps.
