Hi there,
In a way, you are right. Some people are investing in high end animals, and are intending to make money out of them.
I spent good money on my Dwarf Burmese, but I still care for them. They are in lovely vivarium set ups, and if anything, because they are so valuable, I treat them with even more caution.
Many of the larger breeders have been keen enthusiasts all of their life. I cannot name a single person that breeds a large number of animals, that does not actually care about them. Most of these people are so enthused by these animals, that they care for them deeply. Ofcourse, a large breeder will not generally emotionally care for each and every one of his animals, but he will certainly treat them well, its in his best interest.
As for knowing the natural history of these snakes. Well, firstly it is too soon to have re-written Python molurus sp. 'Dwarf Burmese' is just a name. It looks similar to Burmese Pythons, but are much smaller. It is actually quite likely that this will be described as a seperate subspecies, as the differences are quite noticeable. Head scalation and eye location for starters is obviously different.
Now, everyone needs to make a living. Personally, I want to make my living out of doing what I like doing best. That is, keeping and breeding animals. My main passion is Sand Boas, and if anyone wishes to view my extensive collection of Sand Boa species, subspecies and locality variations, please visit my website.
I am willing to spend big money on animals, to make a profit out of breeding them. As far as I am concerned, providing that the animals are treated well, I do not see a problem with this.
Nobody is making promises. I will not guarantee that these Burmese will not grow more than 7ft. However, I can guarantee that these animals are from an isolated population, they are no larger than 7.5ft, they are obviously different, and there will be no more come out of the wild.
I hope this helps a little. It is understandable to be skeptical, but do not disbelieve until you have seen these animals in the flesh.
Lastly, the location of the animals has not been made clear to me yet. I will find out, and as soon as I do, you will be informed. For regular updates, you can go to my web site and join my mailing list.
