skeletal system

The skeletal system of reptiles is mostly composed of hard bones, which has a high degree of ossification and rarely retains cartilage.

Most reptiles lack accessory jaws, so they can't breathe at the same time when eating. Crocodiles have developed bony auxiliary jaws, which enable them to breathe continuously when they are semi-submerged, and prevent the prey in their mouths from damaging their brains when struggling. Lycopodiaceae also evolved a bony secondary jaw.
