The mystery of a snake’s age can be unlocked by understanding the growth patterns and behaviors of different species of snakes. By following a few simple steps, you can accurately determine the age of your snake and better understand its needs. In this article, we will explore the various ways to determine the age of your snake.

Anatomical Age Indicators

Anatomical Age Indicators

Body Size

Snake age can be determined by the size of its body. Young snakes are typically smaller than older ones, as they have not had time to grow. A baby snake may be only a few inches in length, while an adult snake may measure several feet.

Skin Shedding

Another way to tell a snake’s age is to look at its skin. As snakes age, they shed their skin more frequently. A young snake may shed its skin once a month, while an older one may shed its skin every few weeks.


Examining the scales on a snake’s body can also help to determine its age. As a snake grows, its scales become thicker and more defined. Older snakes typically have thicker, more prominent scales than younger ones.

Behavioral Age Indicators

Behavioral Age Indicators

Activity Level

Younger snakes tend to be more active and explore more, while older snakes tend to be more calm and laid back.

Feeding Habits

Younger snakes often require more frequent feedings and more vigorous hunting techniques than older snakes, which are typically less active.

Social Interactions

Younger snakes are often more curious and interactive than older snakes, which may be more solitary.

Environmental Age Indicators

The size of a snake is an important indicator of its age. Young snakes usually grow quickly and reach a length of 1-2 feet within their first year. As they age, they will continue to grow, until they reach their full adult size. The species of the snake will determine how large it can get, but you can use the length of the snake to get an idea of its age. Additionally, the color of a snake can be used to determine its age. Juvenile snakes tend to have brighter colors than mature snakes, so a snake with more vibrant colors is likely younger than one with duller colors. Finally, the skin of a snake can also be used to determine its age. Young snakes shed their skin more often than mature snakes, so if you find evidence of frequent shedding, it is likely that the snake is relatively young.

1. Temperature

1. Temperature

  • A snake’s body temperature is an indicator of age; younger snakes tend to have higher body temperatures than older snakes.
  • Take a temperature reading at the base of the tail with an infrared thermometer.
  • A snake’s body temperature should be around 30-32 degrees Celsius for a juvenile, and decreasing by 1-2 degrees Celsius per year.

2. Humidity

  • High humidity levels tend to make snake skin shed more often.
  • Younger snakes will typically shed more often than older snakes.
  • Increasing the humidity in the snake’s environment will naturally cause the snake to shed more frequently.
  • Examining how often the snake sheds its skin can be a useful indicator of its age.

3. Lighting

Snake age can be determined by examining the eyes. Juveniles often have a brighter sheen, while adults have duller eyes. Additionally, age can be guessed by the amount of wear and tear on the eyes. Older snakes often have foggy or cloudy eyes, while younger snakes have clear eyes.

Frequently Asked Questions

What are the signs of age in a snake?

Snakes age differently from humans and other animals, making it difficult to tell how old a snake is. However, there are several signs to look for that may give an indication of a snake’s age. These signs include: a decrease in agility, a decrease in appetite, a duller, thicker skin, an increase in the number of scale pits, and an overall decrease in size. Additionally, a snake’s eyes may become less bright, and the tail may become shorter.

Are there any special techniques to tell a snake’s age?

No, there are no certain methods or techniques available to accurately determine a snake’s age. However, there are some clues that can help you estimate the age of a snake. These include size and coloration, development of scales and spurs, shedding frequency, and reproductive maturity. All of these factors can help you make an educated guess about the age of a snake.

Is There a Difference in How to Tell the Age of a Venomous Snake Versus a Non-Venomous Snake?

No, the methods used to determine the age of a venomous snake and a non-venomous snake are the same. The most common method is to measure the width of the snake’s head and compare it to a chart of known ages and sizes. Other methods include counting the number of scales or rings on the snake’s body, or examining the pattern of scales on the head.

What are the physical signs of a snake’s age?

A snake’s age can be determined by looking at its physical characteristics. The most common signs to look out for are its size, color, and scale pattern. As a snake grows older, its size increases, its body color darkens, and its scale pattern becomes more distinct. It’s also important to look for signs of wear and tear, such as a duller color and scales that become more raised and jagged. Additionally, older snakes may have a thicker body and more defined head.

Is it Possible to Accurately Determine the Exact Age of a Snake?

No, it is not possible to accurately determine the exact age of a snake. While there are methods to estimate the age of a snake, such as the size, or by counting the number of segments in a snake’s scale, these methods are not entirely accurate. Additionally, there are some species of snake whose age cannot be estimated in any way. As such, it is important to take great care when handling a snake, as it is not possible to accurately determine its age.


In conclusion, determining the age of a snake is not an exact science, and can be difficult to do accurately. However, there are various methods to estimate the age of a snake, such as body size, physical characteristics, and breeding history. While these methods are not foolproof, they can provide some insight into how old the snake is. It is important to be aware of the age of the snake, as proper care and nutrition can vary significantly depending on the age of the snake.
