		Salamandra atra
		
		
		is a fully terrestrial species. Mating involves a ventral amplexus by 
		the male, followed by the deposition of the spermatophore. One embryo 
		develops in each of the two uteri where the developing young first feed 
		on fertilised and later on unfertilised ova in the uteri. Later in 
		development, a zona trophica develops on the border between oviduct and 
		uterus, which continuously provides the young with a cellular material 
		that serves as food. The young develop extremely large external gills 
		which serve as an exchange of nutritive fluid through the maternal 
		uterus. Gestation in total takes 2 years between 650 and 1000 m, and 3 
		years between 1400 and 1700 m elevation. The two terrestrial, fully 
		metamorphosed young are 40-50 mm total length upon birth when they are 
		fully self supporting.  
		
		Longevity is at least 10 years. Length up to 15cm 
		
		Generally considered as of least concern due to the general nature of 
		their habitat potential threats although unlikely are:
