Turtles Are Born With Shells

People have this misconception that shells are separate parts of turtles. NO!

Turtles can not slip in and out of their shells. No such features are available. These reptiles are born with this shield and carry it till death.

The shell development starts in the egg. As the embryo begins to take shape, the shell will also structure and harden around that time.

Yes, it is true that the upper and lower shells grow separately. The carapace comes from the Carapacial Ridge, and the neural crest cell is behind the plastron formation. Only at the last stage of the development do the carapace and plastron fuse at the bridge by suture.

Believe it or not. The shell is an integral part of a turtle’s skeleton. If you dive deep inside the shell, you will find an interconnected web of bones with rib cage and vertebrae. You will be left with a dead turtle if you remove the shell. So, no! Turtles can not live without shells.

The purposes of shells are simple. Such as,

  • Shells protect turtles from predators. The creatures can hide inside the box if they see any animal approaching them.
  • Turtles can feel stressed or panicked depending on their surroundings. Hiding inside the shell is a form of relaxing for these reptiles.
  • In harsh weather, extreme cold, or heat, turtles get in their shells to get comfortable.
  • The shell design is quite impressive. It helps the turtles move under the water swiftly.
