How to Sex a Tortoise/TurtleThe sex of your tortoise/turtle is something all tortoise/turtle owners are curious about, but when
The ShellVery carefully and gently turn your tortoise/turtle upside down so that the bottom of it’s shell is facing upward. If the bottom of the shell is concave (curves inward) then most likely the sex is male.
If the bottom of the shell is flat, then the tortoise/turtle’s sex is a female.
The TailMale tortoise/turtle tails are bigger and longer than female tails.
If you only have one reptile, use pictures online or the ones on this page as a comparison point to know what to expect.
