simple:
Gulf coast had two females they raised up and bred to normal males I believe.
They produced babies similar to the mothers......and then called them labyrinth ball pythons which have NOTHING at all to do or have in common with what you percieve as a labyrinth ball python. The pic you posted is a "labyrinth" ball python that shouldnt be named because it is not proven.
Gulf Coast proved their snakes and called them labyrinth bal pythons. The first generation had alot of abberancies in comparison with the more known cinnamon lines of today.
The babies produced now stil are a little out of whack.
They proved a snake out to be genetic and called it labyrinth.
Remember it has nothing to do with what yo are used to seeing.
Gulf Coast rarely if ever goes on the internet to see what everyone else has, he is always more pre occupied with what he has and he doesnt necesarily keep up with the names of new things.
He called them labyrinths when he proved them, thus in essence all other "labyrinths" are not.
Since his are genetic, and he named them so. Since he proved them, he can name them whatever he wants, just up to the public to accept it.
They are remarkably similar to black pastels aka cinnamon pastels.......
and I would not be surprised if they were compatible.
Now the question is since he was FIRST and not graziani(to my knowledge) then wwhat do we really call them? do we honor grazianis name? or do we honor gulf coasts name?
