Thepresent study investigatedthe morphological variations in vertebral structureamong different vertebral regions in the dice snakeNatrix tessellata,andprovidesa detailed anatomical and microstructural description of the vertebral column.Vertebrae were analyzed and compared using x-ray imaging, scanning electronmicroscopy, micro-computed tomography,and histological techniques. The verte-bral column ofN. tessellatais divided into three regions: precloacal, cloacal, andcaudal. Unlike in many other tetrapods and snakes, the atlas ofN. tessellatadoesnot form a complete ring. It has a flat and roughly trilobate shape with a promi-nent middle lobe. The axis has two hypapophyses. The anterior precloacal regionof the vertebral column has longer and morepaddle-shaped hypapophyses, distin-guishing it from the posterior and mid-trunk vertebrae. The anterior cloacalvertebrae have a short hypapophysis rather than a hemal keel, and the lymphapo-physis extends outward, curving slightly. The cotyle and condyle of the caudal ver-tebrae exhibited a closer resemblance to a rounded shape, while thepleurapophysis extended ventrolaterallyand curved ventrally near its distal end.Paired hemapophyses were present at the posterior-most point of the centruminstead of a hypapophysis. In light of previous fossil findings, our anatomical com-parison of the vertebral and transverseprocesses indicates that the extantNatrixhas a more flexible and less rigid spine than its ancestors. Overall, the vertebraldifferences among snake anatomical regions or taxa are a testament to theremarkable diversity and adaptability of these fascinating reptiles.
