The 11th and 12th pairs of ribs are called floating ribs because they are not attached to the sternum or connected to other ribs through cartilage. Instead, they only attach to the vertebrae in the back, leaving them free at the front. This lack of anterior attachment gives them a "floating" appearance, allowing for greater flexibility and movement in the lower ribcage.
