EGGS

A group of eggs are called a clutch. It takes 1 hour to lay 100 eggs. The nest is in danger because people and animals hunt them for their meat. They can live up to 100 years old.

SHELL

A sea turtles shell has two parts. The top is called a carapace. The bottom is called a plastron. Sea turtles have a shell for protection. Bony bridges join the two parts. The shell is covered with scales. Land turtles can go inside their shell. But sea turtles can't because they have to have their eyes and ears out for protection.
