The members of the genus Draco are called flying lizards, or dragons, because of their ability to glide. These Indian and southeast Asian lizards are arboreal, and their unique mode of locomotion allows them to travel up to ten metres (38.2 feet) between trees without ever touching the floor. Elongated ribs support large wing-like membranes on the sides of the body to generate lift when the reptiles leap from branches.
A snake is essentially a head with a backbone. some species have tiny remnants of a pelvis or limbs, but the skeletons of these reptiles mainly consist of the skull, spine and hundreds of pairs of ribs. While our skull is rigid and has only one joint, the skull of a snake is made up of multiple parts with several joints. Many of the bones are only connected with ligaments, allowing the head to stretch over prey much bigger than the snake. Unlike other fish, seahorses have exoskeletons made up of bony plates fused together. Covered with a layer of tissue, this plating can keep the tiny, slow-moving fish and its vital organs safe from the bites of predators. Even with all the stiff armour, a seahorse is able to curl its tail and grab hold of vegetation and mates to stop itself from drifting away. At the other end of the body, the neck is unusually well defined and flexible.
A frog’s skeleton is all about jumping; long bones in the back legs give their leap its length, and large hip bones support the powerful muscles launching the body forwards. The elongated limbs can be folded neatly against the body when not in use thanks to an extra joint in the ankle. While the back half of a frog is all about movement, it can’t turn its head due to its lack of neck.
