Are animals born in sea shells?
Turtles are "born" with a shell. In the first days after hatching the shell can be softer, because their bones are not calcified all the way yet. Once fully grown, turtles and tortoises have hard, protective shells that are made up of 59 to 61 bones covered by plates called scutes. The scutes are made of keratin, the primary substance in hair, nails and hooves of other animals, but the turtles shell is part of its skeleton. And like bones, it grows with them while they age.
