Answer 2

Males have a concave plastron (the underside of the shell). Females have a flat plastron. Males have their plastron slightly concaved for mounting the female.

Answer 3

If they have long nails then they are males if their nails are short then they are female. Also the males have fat tails and females have thinner tails.
