How to tell the age of a tortoise? Determining the age of a tortoise can be challenging; however, examining growth rings on the shell, size, and general health can provide some indications.
Some Common Methods To Tell a Tortoise’s Age
“Counting Rings” Method:
- Understanding Scutes and Rings:
- Scutes are the scales covering a turtle’s carapace (upper shell), where rings develop.
- Rings form during periods of both proper feeding and scarcity of food, not just during summer and winter, providing a rough age estimate.
- Identifying Rings on Scutes:
- Rings alternate between wider and narrower sections on the scutes, sometimes with varying colors.
- Wider rings represent times of proper feeding (summer), while narrower rings signify scarcity (winter).
- A complete ring cycle (wide + narrow) represents a year; counting and dividing by 2 offers a rough age estimate.
- Carefully count the rings within the scutes, as they can be more visible in some turtle species.
- Calculating Age:
- After counting the rings, divide the total by 2 to estimate the turtle’s age.
- For example, if you count 14 rings, the turtle is roughly 7 years old.
- Note: Counting becomes challenging after 15 years as rings converge.
“Checking The Size” Method:
| Male Plastron Length (mm) | Female Plastron Length (mm) | Age (Years) |
|---|---|---|
| 30 to 40 | 30 to 40 | Newborn |
| Around 75 | Around 130 | 5 |
| Around 100 | Around 160 | 10 |
| A little above 100 | Around 225 | 30 |
| A little above 100 | Around 230 | 40 |
| A little above 100 | Around 235 | 50 |
- Size Assessment:
- Measure the turtle’s length from nose to tail using a measuring tape or ruler, primarily for matured turtles.
- For restless turtles, offer a tempting treat to keep them still during measurement.
- Reference Size Chart:
- Obtain a size chart specific to the turtle’s species from reliable sources online or in libraries.
- Note that turtles in captivity grow faster than those in the wild, potentially skewing age estimations.
- Comparing Length to Age:
- Compare the turtle’s length to the corresponding age on the size chart, especially if it hasn’t reached full length yet.
Note: Actual age determination may vary due to species-specific factors and growth rates influenced by captivity or wild conditions.
Visual Signs Of Age:
In the wild, some turtles exhibit visual indicators of aging, although these signs do not provide precise age information but help determine maturity. For instance, the condition and coloration of the shell reflect whether a turtle has reached adulthood.
Older turtles typically have worn and torn carapaces with dents and chips, while the plastron may remain smooth, and scars may appear on the head and legs. These signs suggest maturity, typically occurring between 10 to 20 years of age.
