interesting, never heard about the tongue before.
In the thread "EBV Red Group x Salmon Jungle" I posted pics of my two jungles and you can see the male's tongue is all black. I do notice that both of mine have a red tint in the upper part of the eye, it's not super noticable but is there. I've heard jungles tend to have that red tint. I'll have to check out the tongue on my other jungle tonight.
And to the original poster's question about their snake, my first instinct is "no, it's not a jungle" but there are traits there so it could be... breeding is the only way to know for sure. It does have the nice 'hold in the head' and some top lateral speckling.
I have a hypo from a litter where the father was a possible jungle that did not prove out, my hypo has some very jungle like saddles but is not a jungle.
Good discussion
