For Verona - JAPANESE Mauremys reevesii

I'm looking for Japanese reevesii. They were once called megalocephala, but I'm not interested in head size; this population has different characteristics from the common Chinese reevesii, and these characteristics aren't limited to the head. No hatchlings, only adults, as it's impossible to distinguish the two populations at birth.
