How Does A Sea Turtle Look Like?
This is how a sea turtle looks like. I hope this helped you 
You tell if its a boy or a girl by its bottom of its shell, if it goes in then its a boy and if its flat its a girl... If you don't believe me ask a scientist
They have a beautiful shell and did you know that sea turtles get killed for jewelry so watch what you buy
A sea Turtle has flippers , hard shells and a small face.
