How to determine the age of turtles

Size and age

The simplest criterion is the size of the dorsal part of the armor of the animal.Options individuals compare with the average for the species.

To determine the age of tortoises and freshwater, at home grown, the exact size will not work. Getting plenty of food, living under favourable temperatures all year round, the reptile grows faster than wild relatives. Pet can significantly outperform the dimensions of statistical data.

Common types of pet turtles — trachemys and Central Asia, do not differ in growth pattern. Neonates hatch with a shell of 2.5-3 cm in length. To year grows up to 5-6 cm by the second year of life is a marked difference between females and males. These types of girls are larger. Two-year-old males grow to 8cm, females are at an inch more. By the third year boys gain another inch of 2 girls about 5. In the fourth year regardless of sex for season 4 of turtle grows up to 2 cm.

The growth rings

Shell free reptile grows in cycles. So in appearance the upper part, you can understand how and how much lived reptile. The intensity of the process is affected by climatic indicators of the location and schedule of its annual activity. Pets reptiles live in stable conditions and do not fall asleep on schedule. Their armor is less prone to wear, as it is not attacked by predators, and is not in contact with rough terrain. To determine how old a turtle on the shell, you need to make amendments on the lives of specific individuals.

The dorsal part of the armor is called karapakkam. It consists of a thick flaps, which are separated by recesses. The joints between the plates in animals up to 4 years light age begin to darken. The shields on the carapace grows from the middle, which are formed on each of the centric grooves. They are called growth rings. In order to know the age slider or Central Asian tortoise on the shell, you need to count the number of grooves on the flap.

The herpetologists recommend take an average between the number of rings on a few panels, because sometimes the parameter doesn't match.

Individuals under the age of two years, the new furrow appears about once in three months. During this time the turtle can be formed from 8 to 12 rings. Reptiles have matured for 12 months there is only one ring. In turtles that do not fit into hibernation, growth rings indistinct, with blurred boundaries.

Other signs

Quality trimming and the condition of the shell does not help in determining the exact age but to distinguish the elderly from a Mature individual. In adult reptiles claws are massive, bigger. Young turtles are more active and active, older individuals lead a regular life.

Signs of old age:

  • erased, monolithic shell;
  • smooth flaps with no growth rings;
  • passive behavior;
  • noticeable wear of the claws.

Burrowing species have a carapace deteriorate faster. This happens due to the friction with the ground until the animal builds and uses the shelter.

The youth trachemys turtles color bright, rich. Over time, the bright stains fade and merge. Red spots on the sides of the head, which gave the species the name, can also give a growth phase. In youth they are bright red, later darkens and becomes brown.

The age of turtles by human standards

Do not try to derive a formula that will allow year of life reptiles be equated to any period of human. For objectivity it is better to rely on the phase of development of the animal. For reptiles to make it more complicated than mammalian Pets. Stages of development of the human body and the turtles there are significant differences.

Childhood is the period from hatching until the onset of puberty. First visual differences between males and females become visible in two years. On average, 5 years to reptiles is able to produce offspring. In captivity, turtles and the Central Asian tortoise can live up to 25-30 years, some species with good care meet 50th anniversary.

Second birthday turtles by human standards, can be compared with decade of the child. To five years the reptile is fully formed reproductive system.

This phase corresponds to the 16th birthday of a person. 20 for Pets the same as for the owner 50. Animal after 30 can be considered the older, and should provide increased attention.

The comparison is important for meadow and steppe tortoises. For breeds with another cycle of development costs to implement the amendment to data on specific species. Similarly, it is possible to compare the age of the Pets from different families and groups.
