Environmental properties, and the behavioral habits of species impact sensory cues available for foraging, predator avoidance and inter/intraspecific communication. Consequently, relationships have been discovered between the sensory ecology and brain morphology in many groups of vertebrates. However, these types of studies have remained scare on snake. Here, we investigate 2 Our results thus demonstrate the value of utilizing endocranial shape as complementary information to size and volume in neurobiological studies.
