In many families, especially in which there are small children, live pets. These are usually cats, dogs, hamsters or parrots. Much less often in a comfortable apartment will meet the representative of the rejection, the turtle. These animals have changed little over the last 200 million years and are distinguished by a large life expectancy (about 150 years). Although in captivity of the turtle rarely live more than 40-60 years. It depends on the care of reptiles. Calculate how many years your favorite is difficult, but maybe.
How the age of turtles depends on its size
At birth, the length of the small turtle armor is on average 3 cm. It weighs it only 10-12. Like newborn children, for the reptile, there are some norms. So, every year they grow by 2 cm. For example, if the measurements have shown that the length of the turtle is 16 cm, then producing simple arithmetic calculations (15-3) / 2, we come to the conclusion that it is 6 years old. By 8-10 years old, a pet grown in captivity becomes 18-20 cm long long. To achieve this turn, growth slows down significantly. It is worth considering that some types of female turtles grow more intense than males.
The calculation method of the rings on the shell to find out the age of the turtle
This method is informative for any type of reptile and similar to the definition of annual rings of trees. The turtle armor consists of a horn and bone layer. The horny shields just born the animal are soft, with time become tougher. For 12 months for 12 months, two or three annual rings are formed. These layers are lighter than the rest of the shell. When the reptiles "knocks out" five years, the horny rings will begin to darken and appear one year annually. Older "Tortyl" is an oval, smooth and pale shell.
Subjective factors indicating the age of the turtle
The habitat is crucial in the content of these reptiles. It is very important to stick to balanced nutrition and the optimal temperature mode. Due to the lack of food and low temperature, the turtle can fall into the hibernation and not to grow at all. In a close and uncomfortable house, a shell is deformed. Adults are distinguished by large claws and a powerful tail, the color of the eyes and the nose changes.
Turtles in our house
In Europe, in captivity most often maintains land reptiles of the following types:
- Bolotnaya - lives 25-30 years.
- Mediterranean - up to 100 years.
- Redeshaw - 40-50 years.
- Central Asian - 40-50 years.
The above facts will help you at least approximately define the biological age of a domestic pet. And if you are just planning to buy a bug in a pet store, you can not get to write and not buy an old sick animal that will not live for a long time.
