Why do turtles have shells?

You may have had one when you were a child, the turtle has become an essential pet over time. But do you really know this animal? The greatest peculiarity of this reptile, it’s obviously his shell. But it is a real mystery for many of us. It exists different kinds of shells depending on the species. Some shells are one piece while others are hinged.

There are even shells which remain soft when the animal is an adult, and others, without being really soft, are soft enough to be flexible. But apart from these specificities, they are all composed of the same basic elements: bone and cartilage. There are also scales of keratin that can cover the shell and reinforce its solidity.

The turtles are real archives of our history, in fact, it is estimated that they appeared 300 million years ago. Today there are more than 300 different species. The shell consists of two parts : the back part and the ventral part. The turtle’s ribs and spine, allow gain in rigidity and solidity of the whole. At birth, the shell is often soft, it will solidify as it grows.

The turtle’s shell is the equivalent of our rib cage but inverted. Depending on the species, changes are observed in the length and shape of bones or joints. The turtle’s shell is a real shield for the reptile. This fortress where it can retreat in case of danger.
