Thus,this statement is not universally true for all reptiles.$2$. In $Amphibians$,the endoskeleton is mostly bony,not pneumatic. Pneumatic bones are a characteristic feature of $Aves$ (birds).$3$. In $Bony 	ext{ } fishes$ $(Osteichthyes)$,the mouth is generally terminal,whereas in $Cartilaginous 	ext{ } fishes$ $(Chondrichthyes)$,the mouth is ventral. This statement is correct.$4$.
