There are two ways to determine how old the beloved turtle has hit: by comparing the length of the shell with the standards, or by counting the number of rings on the shell. However, both options cannot give a 100% result, since there is always some error.
It is necessary
- - Ruler;
- - table of the ratio of age and size of the shell.
Instructions
Step 1
Option one. Measure the length of the turtle's shell and check the table for shell-to-age ratios.
Aquatic red-eared turtle
First year: 6 cm.
Second year: male 8 or 9 cm, female 10 cm.
Third year: male 10 cm, female 14-15 cm.
Fourth year: male 12-14 cm, female 16 cm.
Fifth year: male 15-16 cm, female 18 cm.
Year 6: male 17 cm, female 20 cm
Land turtle
First year: 5 cm.
Second year: male 6 cm, female 7 cm.
Third year: male 8 cm, female 9 cm.
Fourth year: male 10 cm, female 10 cm.
Fifth year: male 12 cm, female 12-13 cm.
Year 6: male 14 cm, female 14 cm
Step 2
Option two. Count the number of rings on the turtle shell. Keep in mind that the first rings appear at an early age, and up to two years of age, there are several, two or three grooves for each year of life. After this age, one groove grows per year. So the first four to six rings will be in a two year period.
Step 3
Consider if the turtle hibernated, grew slowly, or had a poor diet. If the conditions in which she was kept cannot be called good, add another year to the resulting number of years - in poor living conditions or during periodic hibernation, the turtles grow more slowly.
