Western/eastern Herman tortoise

How do you tell the difference between a Western Hermans tortoise and Eastern Hermans tortoise?

 

I believe that the eastern is smaller, but other than that Im not too sure...

 

it should say on your c10 ok

 

Actually, Easterns tend to be larger, for the same age/gender.

Also, Westerns are often more brightly colored, and are considerably rarer (and captive breed/born are considerably more expensive).

Here's a link, from an expert and breeder, that will be helpful: http://tortoiseforum.org/thread-219.html
