Salamandra salamandra subspp. breeding question

[ray]

Which subspecies of the fire salamnder give birth to fully metamorphosed young?

 

[sergé]

For sure only Salamandra salamandra bernardezi from northern Spain, and there are some notes that some populations from S. s. gallaica, S. s. fastuosa and even Salamandra corsica might do so. However, I still haven't seen real evidence for that. And then there is a form within Salamandra algira from northern Morocco that produces fully metamorphosed young.
But don't think it is easier to riase those babies, as most of them are very small at birth (abouyt 2-4 cm) when you compare them with normal metamorphosed Salamandra salamandra (about 5-7 cm).
