Blood pythons (Python brongersmai) are typically found in various shades of red, orange or brown. Nice yellow specimens seem to be few & far between.
This is Mello Yello & Saffron - Malaysian yellow bloods that were produced by VPI nine years ago. They've been breeding for the past week, and the season has just begun, so my fingers are very crossed!
