Can turtles be both male and female?

In sea turtles, the male and females can both grow to the same size. To reliably use shell size as a factor in determining the gender of a turtle, the turtle must have reached its adult size. The bottom of a turtle's shell (called the plastron) is also used as an indicator for determining gender in turtles.

Are turtles intersex?
