If you are still confused about what bones a turtle has, the table below is a brief explanation of it. It is directly under the shell and protected by a shell. The carapace has up to 38 scutes, and the plastron has up to 14 scutes.ĭoes a turtle have a backbone? Yes, the turtle has a backbone that is connected to other bones. The turtle’s shell has an outer shell made of keratin or horn-like material arranged in patches called scutes. The carapace is a combination of vertebrae and ribs. For example, the plastron is a combination of collar bones (clavicles) and rib portions. The lateral bridge connects the carapace and the plastron to become one whole.Īlthough the shells are connected to protect the top and bottom of the turtle, there are openings for the head, legs, and tail.Ĭarapace and plastron are a combination of several bones that are interconnected. The carapace is the dorsal protector, and the plastron is the ventral protector. The turtle’s shell will protect the dorsal and ventral surfaces. The external skeleton or exoskeleton is a sturdy bony outer shell that protects the turtle from all kinds of predators. The internal skeleton or endoskeleton acts as an anchor for the muscles. Turtles have both an endoskeleton and an exoskeleton. Its function remains the same, to protect and enclose the spinal cord. The backbone is informal, and the spine is the formal term for the vertebral column. The difference between backbone and spine is the term. If anyone asks about “does a turtle has a backbone” they also refer to the spine. Since shells are skeletal and interconnected, you cannot separate turtles and the turtle’s shells. You can’t see the turtle’s spine, because it’s fused directly with the armor. Turtles have a spine and are under the shell. It’s just that their backbone is not like reptiles in general. They don’t move from one shell to another, but they hide in it.ĭoes a turtle have a backbone ? Every reptile has a backbone, and turtles are no exception. Don’t be confused if you see turtles that include their head, legs, and tails. The aquatic turtles have longer legs with webbed feet, and land turtles have shorter legs with a club-like shape.Īll turtles, except sea turtles, can insert their legs into the shell if necessary to avoid predators. There is a difference between land and aquatic turtles from the length of their legs. If the turtle’s shell is compromised, it will be a problem to the turtle’s life in the long run. The turtle cannot live without the shell because of it. The shell is attached and structured with bones all over the body. If you add up the bones in the carapace, plastron, and other bones, the sum is more than 70 bones. Turtle’s shell is already a combination of several bones connected and up to 60 bones. Turtles have a backbone whose shoulder blades are inside the rib cage. The plastron is the shell that protects the stomach, and the carapace is the upper shell.ĭoes a turtle have a backbone? Yes, turtles have a backbone. The carapace has 50-60 bones, and the plastron has 7-11 bones. Carapace and plastron have different numbers of bones. In addition to the skull, the turtle has neck bones, shoulder bones, hip bones, and rib bones. Even though it has bones inside, the turtle’s head can still move flexibly when they swim and face pressure waves. The turtle skull is also fused with bone plates. The turtle’s shell includes the bones combined with their ribs. If you want to learn about turtle’s backbone, let’s read this article to the end. Turtle’s shell is very tough and fused with the rib cage and the spine. The shell forms a bony endoskeleton and an exoskeleton. They have vertebrae and consist of two parts. Turtle’s shell is a unique organ like other reptiles with a backbone.ĭoes a turtle have a backbone ? Yes, turtles have backbones. They only have one shell, and can’t be left to get a new one. Turtle is the only reptile that is unique because it has a tough outer shell-like armor to protect its body.
