The tortoise's shell evolved over millions of years as a protective adaptation against predators and environmental challenges. Initially, the shell likely developed from the expansion of ribs and a fusion of bones in the tortoise's back, providing a hard, bony structure. This unique feature not only serves as armor but also plays a role in thermoregulation and buoyancy in some aquatic species. Through natural selection, those tortoises with shells had a better chance of survival and reproduction, leading to the species we see today.

It is in the clock and it is the shell of a turtle
Unfortunately, it is a myth that turtles and tortoises can leave or change their shells. The shell is actually a hard, protective covering over the turtle or tortoise's ribs. So if you find an empty tortoise shell that means that that tortoise has died and decomposed.

A tortoise shells size depends on how big the tortoise is, it's age and its breed.
