I did not take your post as a blast directed towards me.
I was unaware that GTP's drink off their bodies as i have never kept them and my experience with them is very limited.
You are correct in saying that there is a range in epidermal permiability in snakes depending on their habitat, however i think you have over estimated this range. GTP's have developed the ability to osmoregulate their epidermis and have not lost this ability. By saying this you are placing them below that of teleost's. Plasma osmolality of any terrestrial animal is well above that of fresh water.
I have read a journal article on california king snakes that states the the permiability of their epidermis increase 4 fold within the first two sheds after hatching. Developing snakes being almost osmoconfornmers untill late stages of development. I know this species does not live in the same habitat as GTP's so spare me this argument i am simply using it as an example.
