Who noted the peculiar-looking ball python around 1997?

Amir Soleymani

The discovery of the trait that became known as Yellow Belly is attributed to Amir Soleymani. Around the year 1997, Soleymani observed a ball python at a reptile show that was being presented under the generic classification of "Normal." Recognizing that the snake possessed distinct characteristics deviating from the standard wild-type appearance, he acquired the animal. Following this acquisition, Soleymani engaged in diligent work to prove the novelty of the trait, successfully confirming its genetic basis two years later, specifically by 1999. This initial identification by Soleymani marked the beginning of documenting this significant color variation within the hobby.
