In this article, i am going to explain how come tell the period of a turtle. Allow me start by speak that, over there is nobody reliable method to determine the period of a tortoise accurately. There space some methods to guess: v the age, but these techniques are no 100% reliable. If you desire to determine the accurate period of her turtle, you’ll need to know once it was born. Otherwise, unfortunately, you can only guess: v the period of a turtle.

You are watching: How to tell how old a turtle is

There room basically two approaches to guess: v the age of a turtle. These approaches are counting the rings on the turtle’s carapace (upper shell) and comparing the dimension with another same varieties of turtle. However, as I have said before, both of these methods are only great at guessing the period of the turtle.

“Counting Rings” method:


In this method, us count the ring on the spine of the turtle’s upper shell. The scutes room basically the scales the cover the turtle’s carapace. Generally, the ring only develop in times of proper feeding and scarcity that food. In various other words, the ring can kind when the turtle was effectively fed or seriously famished, not only during summer and winter. So, this an approach can only give a rough estimate that the turtle’s age.

You can observe the ring on the scutes of the turtle’s carapace. You deserve to see the the rings alternative between a wider ring and also a narrow ring in the scutes. The ring can likewise alternate between colors. Generally, the broader ring represents the time as soon as the turtle was appropriately fed, additionally considered as the summertime. ~ above the other hand, the narrow rings represent the time that scarcity of food, i m sorry is also considered together the winter time. So, theoretically, a broad ring and also a small ring both forms up a totality year. So, if you count all the rings and also divide that by 2, friend should gain a stormy estimate of the turtle’s age.Do not count the scutes. You need to count the ring within the scout. In some turtle species, the ring are more visually influential than the others.After you’ve counted the rings, you simply need to division it by 2. Suppose, did you do it counted 14 rings. Then the turtle’s period should be about 7 years old. However, the is an overwhelming to count the ring after the turtle has passed 15 years, together the rings gain closer v age.

“Checking The Size” Method:

Male Plastron size (mm)Female Plastron length (mm)Age (Years)
30 come 4030 come 40Newborn
Around 75Around 1305
Around 100Around 16010
A tiny above 100Around 22530
A tiny above 100Around 23040
A tiny above 100Around 23550
Please keep in mind that the data thought about here are simply a basic assumption. Actual data can vary depending on the types of the turtle and also many other factors.

In this method, us measure the size of the turtle to get a stormy estimate of its age. Here’s how this technique works:

This method is largely applicable because that matured turtles. You need to measure the size of your turtle from tip of the nose to the tail. You deserve to either usage a measuring ice or ruler. If you challenge a hard time to save the turtle still, a tempting treat have the right to help.Once you gained the dimension chart, compare her turtle’s size in the chart against the age. This method particularly functions if her turtle hasn’t reached its complete length yet.

Visual indicators of age:

Some turtles, specifically in the wild, present some visual signs of aging. Though these indicators don’t phone call the exact age of a turtle, these are beneficial to identify whether a turtle has actually reached maturity or not. For example, in wild, the shell’s condition, and also its coloration, show whether a turtle has actually reached adulthood or not. In wild, the carapace of enlarge turtles is an ext worn and also torn. The carapace can likewise have dents and chips. If the plastron can be smooth, there can be scars ~ above the head and also legs. Such indications tell that a turtle has reached that is matured age, i beg your pardon is roughly 10 to 20 years old.

These indications are not prominent in captive bred turtles, as the shells the captive-bred turtles execute not sustain injuries like wild turtles. So, this technique won’t work-related well for turtles in captivity. Also, some turtles begin to acquire darker together their period increases.

Giving too lot priority on the problem of the covering to identify the period is no recommended. A turtle that has lived on bad nutrition will flourish a negative shell and can look older than it is actually. Turtles that didn’t have actually a proper diet for number of years can flourish a bumpy, rough covering which will give you a false analysis of age. So, the visual indicators are no 100% reliable once determining the age of a turtle.

Examining the bones:

While this method is not for any kind of average tortoise keepers, scientists have started to use this technique for identify the age of sea turtles. The clinical name because that this technique is skeletochronology. The method this technique works is, theoretically some bones in sea turtles produce annual rings. So, by counting this yearly rings, we can determine the period of the turtle.

However, a team that investigators under Dr. Brian Wallace native the “Non-profit Sea turtle Conservation Organization” has actually revealed the this an approach produced mixed results. According to Dr. Wallace, this an approach worked well v some types of the sea turtles, such as Kemp’s Ridley Sea tortoise species. However, the didn’t occupational on some varieties like the leatherback sea turtles.

How to tell the age of a red-eared slider turtle:


Red-eared slider is among the most well-known pet turtle in the USA. Castle can quickly live for up to 50 year in captivity. It is really difficult to identify the age of a slider turtle uneven you recognize when it has actually hatched. However, there space some approaches which can assist you guess the period of the slider turtle. Below are the steps to guess: v the period of a red-eared slider turtle:

When the red-eared sliders space hatchlings, castle get really bright coloring. The shells are dark environment-friendly with bright yellow markings all over it. However, the colors begin to fade after around 1 year. The dark green color fades right into an olive hue. After about 2 years, the red markings alongside the ears begin to disappear. The shell also turns into a brownish color.Another method to assumption: v the period is by measuring the size of the carapace. If the tortoise is simply hatched, it’s carapace will certainly be shorter than her thumb. As soon as the turtle is 2 years old, its carapace must be about 4 inches long. By the time the carapace reaches 6 to 8 inches long, the turtle is at least 4 years old. For this reason the development of the carapace proceeds until that reaches about 12 come 13 inch long.The third way is to watch the turtle’s front and also back. Male red-eared sliders start to grow large claws and also tail after ~ the period of 2. The claws start to acquire refined and prickly between the age 2 and 3. After ~ that, the claws get shorter and duller as the turtle proceeds to age.

How come tell just how old a painted turtle is?


Like red-eared sliders, painted turtles room also really common and popular in the USA. Here are the steps to guess just how old a painted tortoise is:

We should observe the abdominal area. The abdominal muscle area will likely be in the center of the plastron, contempt on the lower half. You should see around 8 part there. There will certainly be two abdominal muscle areas. Choose only the left or the ideal one.Now you should count the rings. Every ring to represent a complete growth cycle. The an initial ring have to be counted together zero together it is present when the turtle is born.You deserve to guess the period of the tortoise on the number of rings. If the ab area has actually 5 rings, climate the tortoise is likely 4 year old (as you have counted the first ring zero). This is not precise estimate, rather than an educated guess.

How to tell just how old a snapping turtle is?


Guessing the age of a snapping tortoise is very difficult, particularly when the tortoise is matured. Count the rings to acquire an estimated period is a trustworthy way, yet it doesn’t work on matured species. Sometimes, the shell condition and also the size additionally gives a an excellent estimation that the period of the snapping turtle.

Many tortoise keepers counting the growth rings to obtain an estimated age of the snapping turtle. You have the right to observe the growth rings on the scutes of the snapping turtle. The scutes grow an extremely quickly when there is many of food for the turtle. On the contrary, the growth rate that the scutes slows down when there is a scarcity the food. Each ring normally represents an annual cycle. So, if the snapping turtle has actually 7 rings, the is likely to it is in 7 years old.The shell gives a very tiny clue once determining the age of a snapping turtle. It deserve to only tell united state whether the snapping tortoise is a hatchling or not. Generally, the hatchlings have actually three ridges on their carapace. As they grow, the ridges start to disappear and also the carapace gets smoother. So, if your snapping turtle has a smooth carapace, the is likely to it is in at the very least a couple of years old.

So, this is my in-depth guide on exactly how to phone call the period of a turtle. Choose I have said before, there space no definite ways which can specifically tell a turtle’s age. These methods deserve to only offer you a calculated guess: v of the turtle’s age.
