Can you tell the age of a snake by the number of vertebrae it has?

Snakes are fascinating creatures, and many people wonder if it is possible to determine their age by counting the number of vertebrae they have. Unfortunately, this is not an accurate method of determining the age of a snake.

The number of vertebrae in a snake's body varies greatly depending on the species, as well as other factors such as diet, habitat, and genetics. For example, the common garter snake has an average of 150-170 vertebrae, while the ball python has around 100-400. Additionally, snakes continue to grow throughout their lives, and the number of vertebrae they have can change as they age.

Therefore, it is not possible to accurately determine the age of a snake based on the number of vertebrae it has. Other methods of determining snake age, such as counting growth rings on their scales, can be used for some species but are not always reliable.

In conclusion, while counting the number of vertebrae in a snake may seem like a logical way to determine its age, it is not a reliable method due to the large variations between species and the ongoing growth of snakes throughout their lives.

Not necessarily. The number of vertebrae in a snake can vary depending on the species and the individual snake's size. For example, a newborn corn snake has about 200 vertebrae, while a full-grown corn snake has about 260 vertebrae. Additionally, the number of vertebrae can change as a snake grows. For example, a snake that has been injured or has had a growth disorder may have more or fewer vertebrae than a healthy snake of the same species.

However, there is a technique called skeletochronology that can be used to estimate the age of a snake by counting the number of growth rings in its vertebrae. This technique is most accurate in snakes that have a relatively slow growth rate, such as garter snakes.

To perform skeletochronology, a thin slice of bone is taken from the vertebra and examined under a microscope. The slice is then stained to make the growth rings visible. The number of growth rings can then be counted to estimate the age of the snake.

It is important to note that skeletochronology is not an exact science and there is always some error involved in estimating the age of a snake. However, it is a useful tool for scientists who study snakes and can help them to better understand the life history of these fascinating creatures.
