Tintenfisch,
I wonder if imperfect regeneration is not more the norm than the oddity, particularly if there is any kind of venom involved. Our dog was bitten by either a snake or a spider (vet could not determine but felt it was probably a brown recluse since there was only one puncture wound). After sluffing off the contaminated tissue, not only did the leg regenerate somewhat oddly, the dog developed odd growths in other areas of the leg. The growths and the now misshapen leg have not caused the dog problems and she has already lived a "normal" lifespan for the breed but her body went into overdrive trying to heal the wound and seemed to over produce the replacement parts.
