I hate the Jaguar!

[Gio]

I have had several reticulated pythons do that when they struck at the feeder, missed, and grabbed themselves. Most of them figured out pretty quickly what happened and let themselves go, but I do have one female that held onto herself and made a big ball-o-python for about ten minutes and she has no neurological problems.

Fortunately their teeth are pretty short for their overall size, so even when they do bite themselves they don't do a lot of damage.

The behavior is not necessarily the result of the JAG gene, I'm not a fan of JAGs but I've had a retic that has done the exact same thing that BCR has described.

An overly aggressive feeding response isn't due to a defect. Jitters, corkscrewing and inability to self right are the typical signs.

Retics are known to miss their prey and bite themselves or the next closest thing during intense feeding moments.

My coastal carpet has never done it however I think an active carpet with a strong will to feed could "self bite" if it misses the prey.
