An 18ft male burm is not like a 7ft man, it's like a 9ft cornsnake. Still, Ill wait for pictures as I don't know of one that exists and in my opinion it doesn't (it's like you said; an unconfirmed report). Just calling it like it is. Ive been doing this for a while my friend, I don't have one source. Been working with a well known breeder that handles 500+ retics and burms as of late changing cages for him in exchange for tattoos and he seems to agree when I brought this up last night as well.
