Two points:
Abrahm: The glands on the head are not parotid glands, they are parotoid glands. Two different things, similar spelling, common mistake (too common!).
If memory serves, and it usually does, Salamandra salamandra have four lines of poison pores running from head to tail - two along either side of the midline of the back (you're seeing one of these quite clearly in the photo) and one on each side of the body, about 2/5 of the way down (you can almost make these out in the photo).
Well done Stefanie!
