Neurological deficits in jaguar pythons:
Some neurological deficits have been associated with jaguar pythons, a morphological variant of the coastal carpet python (Morelia spilota mcdowelli sub-species). These deficits can range from those that are so mild they are essentially non-detectable, to animals that move in a spinning, back-flipping or corkscrew motion. More subtle effects can include poor coordination, striking aim, or "righting ability" (keeping their head level when turned over).
The vast majority of jaguar pythons have the milder forms of these deficits, barely noticeable unless the animal is handled. In the opinion of some breeders, even jaguars that appear totally normal are a little "less athletic" than most carpet pythons.
These neurological deficits can be present upon hatching, or in some cases, develop years later. One hypothesis is that the "jaguar gene" is coupled with a vulnerability to neurological problems, and that these problems do not appear unless the animal undergoes some kind of stress. The majority of jaguar pythons that develop these effects seem to display them at an early age (less than a year). In most jaguars, these neurological effects may vary a bit over the lifetime of the snake, but do not appear to significantly deteriorate over time. They do not appear to effect the
overall health or breeding ability of the jaguar python, nor is their any predictable pattern of inheritance for progeny that have come from a neurologically affected sire or dam jaguar python.
