eDNA is the idea of taking a environmental sample like water or air, and finding traces of DNA and figuring out what creatures live in the area. you wouldn’t take a sample from an animal mouth to check for eDNA.
you could tell what salamanders live in a pond by getting eDNA from the water, but no real point in checking the DNA in the salamander mouth.
I’d be pretty impressed if salamanders readily incorporated environmental transposons into their genome. Don’t octopuses rewrite their genetics on the fly though? I think I remember reading something about that years ago

maybe to double check results for testing.
