hey buddy, Joe here..
I saw that ad and knew you would catch heat too.. lol (those kwazy people! you can't please them all! lol)
The reason being, I would say it is not a 'high expression' at all, actually a low expression, BUT, it has extremely strong Jungle CHARACTERISTICS!
...such as bold, contrasty pattern, strong, intense dark pattern, bold and bright light pattern, thick, well pronounced borders around the tail blotches and such, and wacky head pattern and eyes. Not to mention those HUGE, BRIGHT WHITE circles at the sides of each saddle!
Those are all Jungle Characteristics that are highly exagerated on this snake, and technically that is totally different than what most people refer to as 'high expression' these days, which would mean what you had mentioned, more like a full striped or chain linked boa.
These days, Jungles are being bred into other lines, such as Salmons, OrangeTails, Central Americans, BCC, and more, so we are seeing different expressions coming out.
Some are different in color - some might be intense yellow and have pinks and yellows too, while some you see have more of that bone white color with darker pattern all together.
Some lose pattern intensity, some gain it.
Some typically throw more chain links, or stripes, and some throw more of the blocky saddle look.
EITHER WAY, you can and will produce 'high expression' Jungles from a 'low expression' adult, i've done so many times, as have many others.
So, bottom line, that's a beautiful Jungle!
Just hard to please everyone when it comes to detailed descriptions and such. Always has, always will be.
All the best, Joe
