Functional morphology of the tongue of snake Bothrops jararaca (Reptilia: Squamata)

The tongue has a series of functions that can be related to feeding, such as transporting food to the back of the mouth, sensory function and capturing prey. The tongue of the reptiles has great morphological and functional variations between orders. This study aimed to described the morphological c...
