Measuring Size and Weight
Measuring the size and weight of a field turtle can present invaluable data 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). Document the measurement in millimeters or inches.
2. Measure the Carapace Width
Measure the straight line distance throughout the widest level of the carapace. Document 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). Document the measurement in millimeters or inches.
4. Measure the Plastron Width
Measure the straight line distance throughout the widest level of the plastron. Document this measurement in millimeters or inches.
5. Weigh the Turtle
Use a kitchen or postage scale to weigh the turtle. The size must be correct to inside 1 gram or 0.05 ounces. Document the load in grams or ounces.
| Measurement | System |
|—|—|
| 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 Based mostly on Remark
Figuring out the age of a field turtle shouldn’t be an actual science. Nonetheless, there are a number of strategies that can be utilized to estimate the age of a turtle primarily based on its look and conduct.
Dimension and Weight

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 rely the scute rings, you will want to look at the turtle’s shell underneath a shiny mild. The rings are most seen on the scutes on the highest of the shell (carapace). Depend the variety of rings on a number of completely different scutes and take a mean to get a extra correct estimate.
Measuring the Carapace Size
The size of a field turtle’s carapace (high shell) will also be used to estimate its age. The connection between carapace size and age shouldn’t be 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) will also be used to estimate its age. The connection between plastron size and age shouldn’t be 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 usually are not at all times correct, however they will present a common estimate.
Further Elements to Take into account
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 |
