Measuring the size and weight of a field turtle can present invaluable info for figuring out its age and total well being. Observe these steps:
1. Measure the Carapace Size
Place the turtle on a flat floor and measure the straight line distance from the entrance to the again of its shell (carapace). Report the measurement in millimeters or inches.
2. Measure the Carapace Width
Measure the straight line distance throughout the widest level of the carapace. Report this measurement in millimeters or inches.
3. Measure the Plastron Size
Flip the turtle over and measure the straight line distance from the entrance to the again of its backside shell (plastron). Report the measurement in millimeters or inches.
4. Measure the Plastron Width
Measure the straight line distance throughout the widest level of the plastron. Report this measurement in millimeters or inches.
5. Weigh the Turtle
Use a kitchen or postage scale to weigh the turtle. The size needs to be correct to inside 1 gram or 0.05 ounces. Report the load in grams or ounces.
| Measurement | Formulation |
|—|—|
| Carapace Size | CL = Distance from entrance to again of carapace |
| Carapace Width | CW = Distance throughout widest level of carapace |
| Plastron Size | PL = Distance from entrance to again of plastron |
| Plastron Width | PW = Distance throughout widest level of plastron |
Estimating Age Primarily based on Statement
Figuring out the age of a field turtle isn’t an actual science. Nevertheless, there are a number of strategies that can be utilized to estimate the age of a turtle primarily based on its look and habits.

Counting Scute Rings (Scutes)
Scute rings are development rings that seem on the scutes (scales) of a field turtle’s shell. Every ring represents a yr of development. To depend the scute rings, you’ll need to look at the turtle’s shell underneath a brilliant mild. The rings are most seen on the scutes on the highest of the shell (carapace). Rely the variety of rings on a number of totally different scutes and take a mean to get a extra correct estimate.
Measuring the Carapace Size
The size of a field turtle’s carapace (prime shell) may also be used to estimate its age. The connection between carapace size and age isn’t as exact as counting scute rings, however it may present a common estimate.
Measuring the Plastron Size
The size of a field turtle’s plastron (backside shell) may also be used to estimate its age. The connection between plastron size and age isn’t as exact as counting scute rings, however it may present a common estimate.
Evaluating to a Reference Chart
There are a number of reference charts obtainable that present an approximate age vary primarily based on the size of a field turtle’s carapace or plastron. These charts should not at all times correct, however they will present a common estimate.
Further Components to Think about
Along with the strategies described above, there are a number of different components that may have an effect on the accuracy of age dedication, together with:
| Issue | Impact on Age Estimate |
