What defines the Class Reptilia grouping for G. insculpta based on taxonomic ranks?

Answer

Tetrapod, possessing scales, and being ectothermic (cold-blooded).

The classification of the wood turtle into the Class Reptilia places it within a specific biological group defined by several key characteristics. Reptiles are fundamentally characterized as tetrapods, meaning they possess four limbs. They are covered in scales, which is a defining integumentary feature. Furthermore, they are ectothermic, commonly referred to as cold-blooded, meaning they rely on external environmental sources to regulate their body temperature, contrasting with warm-blooded animals. These characteristics define the Class Reptilia, which is situated above the Order Testudines in the Linnaean hierarchy.
