Most reptiles have best developed good movement of the snout relative to the braincase. Some aquatic turtles and crocodilians have the best developed separation of air and food passages. Fish have a very short oral cavity. Tetrapods typically have longer oral cavities. Human mouth is highly covered by an upper and lower lip.

Function of oral cavity:: Ingestion which is a series of biologically activities (capture, incision, transport, mastication, swallowing and, in infant mammals, suckling). The oral apparatus contains the dentition, the masticatory muscles, numerous bones of the cranium, the squamosal - dentary joints connecting the lower jaw to the skull, the tongue, and many other structures in the head. Mammals are distinguished from other vertebrates in many aspects of ingestion including mastication which does not occur in some other vertebrates . Food transport and swallowing are less complex and involve the coordination of fewer muscles and other soft tissue structures. Suckling is a behaviour that is unique to mammals. Among mammals, the feeding habits varied and classified into : Herbivores. Carnivores. Insectivores. Frugivores . Omni-vores. Structures that are adapted in mammals for use during ingestion include the dentition, the chewing muscles, the lips and the lip musculature, the cheek musculature, the cranial bones, the palate, the tongue, and the pharynx.
