@thebrainmaze: Most baby reptiles hatch using a temporary structure called an egg tooth, a small sharp tip on the end of the snout that helps them crack through the eggshell from the inside. Unlike true teeth, it is not used for eating or defense. Once the hatchling emerges and no longer needs it, the egg tooth gradually falls off or is reabsorbed by the body within a few weeks, making it a remarkable one-time adaptation for survival.
