That's right, as we have no native salamander species here in Aus, breeders have spent the past two decades perfecting the morphing technique. They have even been selectively breeding the parents of the best morphers and apparently have got to the point were some bloodlines of axolotls start the process naturally and only a very dose dose of iodine or hormones are required to complete the process. The morphed axolotls these days are much more robust and active compared to those available 10-15 years ago so the breeders are obviously doing something right
