Do Snakes Have Bones? 12 Facts About Why They So Wiggly

When someone sees a snake, it’s natural for them to wonder, “Do snakes have bones?”

Even though it has no arms or legs, the animal is so flexible that it can kill its prey by squeezing it, wrap itself around a tree branch, or even wrap itself around itself.

On the other hand, a snake is a vertebrate with a skeleton, which means it not only has bones but also a backbone to hold those bones together.

Read on to find out more about snakes as we answer the question in more detail. Don’t snakes have bones?

Do Snakes Have Bones?

Snakes do have bones, despite what most people think. Depending on how big and what kind of snake they are, they may have hundreds of bones.

In contrast to mammals, snakes only have a few types of bones, such as the skull, jawbones, and backbone with vertebrae and ribs.

Because snakes’ bodies are so different, their organs are also different. The throat takes up about a third of the front half of these reptiles’ bodies, while the kidneys, liver, lungs, and stomach are all long and thin.

Do Snakes Have Bones

A Snake’s Basic Structure

There are two types of animals: those with backbones and those without. Vertebrates, on the other hand, have a backbone. Even though it may be hard to believe, snakes and all other reptiles, birds, mammals, and fish are vertebrates.

All of these animals have skeletons on the inside. The bones give our bodies shape and support.

When our muscles contract, they attach to our bones, which lets us move. Snakes must have a lot of bones so that they can move and be strong.

Number of Bones in Snakes

Snakes have fewer types of bones than mammals and many other animals, but they have a lot of them. The number of bones in a snake depends on the type of snake.

Like the puff adder, a viper with a short body will have about 180 vertebrae in its backbone. A snake with a long body, like the mamba, can have as many as 400 vertebrae. Two ribs are connected to these vertebrae.

Ribs and Vertebrae

Snakes have ribs and vertebrae that make up their flexible backbones. They also have skulls and jawbones with teeth. The only vertebra that doesn’t have two ribs is the tail.

The backbone’s front and back ends have bony extensions that hold the end vertebrae in place. This gives the backbone flexibility and keeps it from moving out of place.

Most reptiles have one set of zygapophyses on the front and back of each vertebra. A snake, on the other hand, has two sets of zygapophyses on the front and back of each vertebra.

This means that each vertebra in the snake’s vertebral canal connects to the next vertebra in five places. This gives the snake’s joints strength.

One snake joint isn’t flexible, but as the snake grows, more and more of its joints become flexible.

The ribs of a snake don’t fit together and have loose ends. This lets the snake grow and shrink when it eats animals that are much bigger than it is.

For example, when a cobra makes a hood, it pulls its upper ribs up. The hognose snake protects itself by pulling its ribs in and standing up straight. The snake doesn’t have a breastbone, which makes it easier for it to eat.

The ends of a snake’s ribs have forks and are twisted and bendy. They protect the snake’s organs, which are long and thin like those of other reptiles.

Since snake ribs aren’t connected to the sternum like human ribs are, they can expand like the snake’s jaws to catch big prey. The king cobra can raise its front ribs and stretch them into a hood to show how dangerous it is.

The Skull and Jaws

A snake’s problem is that it is a predator with a thin body and no arms or legs to hold and keep its prey.

Even if a snake had teeth like a lion or leopard, it would still be hard for it to digest its food. So how does a snake that doesn’t have legs eat?

Snakes have to find a way to make their prey unable to move before they can crush it or poison it to death.

Some snakes, on the other hand, swallow their prey while it is still alive. The snake’s flexible skull bones come into play here. Depending on how big the prey is, the jaw gets bigger.

The upper jaw is made up of several separate bones that are held together by ligaments that are very flexible. Since these ligaments are so flexible, they can pull the bones up and out.

The lower jaw is made up of two long bones that are attached to the back of the skull by flexible ligaments. Because the higher bones can move up and out, these bones can open down and out.

This lets the snake eat animals that are up to three times its size.

The snake’s fangs are strong enough to hold the prey, but they can’t chew. The prey is caught by the snake’s fangs, which move back and forth to push it down the snake’s neck.

Because this can take a long time, the snake breathes in by extending its windpipe from its mouth.

Snakes also need to get new teeth every so often.

Vestigial Limbs of Snakes

Lizards are the ancestors of snakes, and some lizards with shorter legs figured out a long time ago that they were better in some situations. So, the legs of this group got shorter and shorter.

It was passed down from generation to generation until snakes started being born without legs. Even though snakes don’t have legs anymore, many python and boa species still have the back legs of pelvic spurs.

Why Is It Beneficial to Have So Many Bones?

Snakes can move in many ways because they have so many bones. A vertebrate like a human, which has a lot fewer bones than a snake, would not be able to twist and turn like a snake. One-on-one comparison.

Composition of Snake Bones

Snake bones are similar to vertebrate bones in how they look and how they are made. They are made up of many different tissues that work together to make a structure that is both light and strong.

Most bones are made of the protein collagen, which makes them flexible and keeps them from breaking. Mineral salts, like calcium phosphate, also help bones grow and get stronger.

Is It Possible For Snakes To Break Their Bones?

Yes. Snakes are very strong, but their bones are easy to break. Snakes can break or hurt tens of thousands of ribs.

Snakes in the wild can’t get treatment to help their bones heal, which is sad. They will, however, get better on their own in the long run.

Is it Possible to Eat Snake Bones?

In theory, you could eat snake bones, but only because they are not poisonous or dangerous. But snake bones don’t taste very good, just like the bones of any other animal. Snake bones are also small and thin, which makes them easy to break.

If they tear or hurt your digestive system, you shouldn’t eat them because this could cause problems.

Why Is Having So Many Bones Useful?

This animal is flexible in part because it has a lot of bones. People, who have a lot fewer bones than snakes, could never bend and twist like snakes. The many bones in a snake’s back help to keep its spinal column strong and protect its spinal cord.

Where Does a Snake’s Tail Begin?

Another thing someone might wonder is where a snake’s tail starts. Is it even possible to call it a tail when its whole body is just one long tube that gets thinner?

On the other hand, snakes do have the right kind of tails. As the spine gets closer to the end of the animal, the ribs get smaller.

Do Snakes Have Bones

Some snakes, like the rubber boa, do not belong to this group. This boa’s back end is as big as its front end, and when it feels threatened, it curls up into a ball, tucks its head in, and sticks its tail out.

Predators mistake the snake’s tail for a ready-to-strike head, and even if they bite it off, it’s not a vital part of the snake’s body.

Most of the time, the snake’s tail is made of caudal vertebrae, which are at the very end of the body and don’t have ribs.

The haemal arch, which is at the base of the tail, is another part of the tail. It connects to the vertebra to make a blood vessel canal, which lets veins and arteries go through the tail.

Seven or eight of the last vertebrae in a rattlesnake’s tail are joined together, but the rattles are not made of bone. Keratin, the same thing that makes up fingernails, is used to make them.


Snakes do have bones, despite what most people think. Depending on how big and what kind of snake they are, they may have hundreds of bones.

In contrast to mammals, snakes only have a few types of bones, such as the skull, jawbones, and backbone with vertebrae and ribs.

Because snakes look so flexible, it’s easy to think they don’t have bones. People often think they are invertebrates because they can move around and wrap their bodies around different things.
