Did you know?
Sea turtles have beaks instead of toothed mouths. This is a feature they share with birds and some dinosaurs. The beak is a piece of keratin that is self sharpening and continually grows. FYI - Human keratin forms our finger nails!
The shell acts as the sea turtle's armor. The shell is composed of bone plates covered with collagen, and scutes. The scutes are the tuff outer scales (also made of keratin) which covers the shell giving it color and texture.
