How should a Brazilian tortoise be aged?

There are two ways to identify the age of a tortoise. One is to look at the abdominal spots of the turtle towards the sky, each abdominal spot has a circle pattern, each circle represents a year (some have two circles or no circles), and a few circles represent how old they are, basically so; Another way is to look at the carapace on the back (the so-called thirteen hexagons), each carapace also has circles, and the number of circles represents the age.

The Brazilian turtle is also known as the red-eared turtle and the painted turtle.

Features: The head, neck, limbs, and tail are covered with yellow-green inlaid stripes of uneven thickness, and there are 2 thick red stripes on both sides of the top of the head. The cornea of the eye is green with a black dot.

Snout blunt. The dorsal and abdominal armors have yellow and green inlaid and irregular spots on each shield piece**, and the pattern of each turtle is different. Webbed between the fingers and toes.

The tail is moderate. Brazilian tortoises spend most of their time in water and prefer to be in clear water. Therefore, the quality of water is very important. In summer, the water is changed once every 10-15 days.

If the water color is brownish-green or blue-green, it indicates that the water quality is too "fertile", and all the water should be changed in time. From June to September, due to the high temperature, the water change should be carried out 3-4 hours after feeding. In winter, the turtle can change the water less or no water during the hibernation period.

The turtle has large dark spots on its abdomen, has a fierce personality, is agile, and is more aggressive. And the skin is smooth, the body is thin and the skirt is wide, and the fat color is golden. In terms of taste, nutrition, safety and other indicators, it has surpassed wild soft-shelled turtles.

Distinguish the male and female, look at the pattern on its abdominal carapace, if it is a hollow circle pattern, it is a female, if it is a solid pattern, it is a male turtle.

Age identification: Look at the lines of the back armor, one thick and one thin two lines are one year.

Brazilian tortoises should be distinguished from the quality of the flesh.

Kill your turtle first. Tun for two hours. The older ones are the old turtles. The meat is more tender, and it is a tender turtle.

When you tell the age of the Brazilian tortoise, you can look at its abdominal spots, which usually have a lot of irregular circles on them, and you can know the age of the Brazilian tortoise by counting the lines in these circles.

There are many concentric rings on the dorsal carapace of the Brazilian tortoise, and this ring pattern represents a year, and when looking at the age, the number of rings is increased by one to the age of the Brazilian tortoise.

The age can also be judged according to the size of the Brazilian turtle, usually about five or six centimeters of age is about one year old, about ten centimeters of Brazilian turtles are only three years old at most, and more than ten centimeters are more than three years old.

First of all, we can turn the turtle over and turn its belly towards us, and then we can see the abdominal spots on its abdomen, which are all circled. Each circle represents a year, and several circles represent a number of years, so that we can roughly estimate the age of the Brazilian tortoise.

In the second step, we can look at the concentric rings on the turtle shell, each circle represents a year, that is, a growth cycle. Based on the number of concentric rings, one is then added, so that the age of the turtle can be calculated. The premise of using this method is that the concentric ring pattern of the turtle must be relatively clear, so that the calculated result is more accurate.

If it is a warm-fed turtle, it is not suitable for this method.

Third, the age can be deduced from the weight of the turtle. Generally speaking, a one-year-old turtle weighs about 20g, a two-year-old turtle weighs about 60g, a three-year-old turtle weighs about 110g, a four-year-old turtle weighs about 210g, a five-year-old turtle weighs about 260g, and a six-year-old turtle weighs about 450g.

Fourth, the age can be calculated by measuring the ratio of the head to their body, and the larger the shell, the older the turtle, the older they will be. But if the shell reaches more than 18 centimeters, the age of the Brazilian turtle at this time is not easy to calculate. Because at this time they belong to adult turtles, and the shells of adult turtles do not grow much.

How old the Brazilian turtle can be seen from three aspects. 1.Looking at the texture of the turtle's back shell, the dark color and clear texture indicate that the older and older the age.

2.Look at the concentric rings of the turtle's back shell. Every winter, when it stops growing, it grows a growth ring, one ring represents a growth period, and the number of circles represents its age.

3.Look at the weight. It is about 15 grams for one year, about 50 grams for two years, and about 100 grams for three years.

Questions. So how do you judge the male and female?

I'm a bit blind to judging the sex of animals, I'll send you a ** to see, okay.

I'm a bit blind to judging the sex of animals, I'll send you a ** to see, okay.

Regarding the Brazilian tortoise to distinguish between male and female, we can do the following:

First, the body size of the female is generally larger than that of the male; Clause.

Second, look at the female of the front paws shorter than the male; Clause.

3. Look at the short tail of the female and the length of the male; Clause.

Fourth, look at the turtle shell mother turtle shell generally presents a round and thick shape.

With the periodic change of nature, the turtle has an obvious growth period and hibernation period, the dorsal carapace shield grows like the body during the growth period, forming a loose and wide concentric ring circle, the tortoise enters a dormant state during the hibernation period and stops growing, and the dorsal carapace shield almost stops growing, forming a narrow and tight concentric ring circle. Such dense concentric rings are similar to the age of a tree based on its growth rings, and a growth ring occurs when it experiences a winter when development stops.

Based on this, the age of the turtle can be determined, that is, the number of concentric rings on the shield, and then add 1 (the broken shell is born as a ring), which is equal to the actual age of the turtle. However, this method is only clear before the turtle's growth rings before the age of 10, and the status quo will be blurred after that.

You can also look at the shell of the turtle's abdomen, which also has a circle of circles, each circle also represents the year of the turtle, and the age of the turtle can be roughly estimated according to the number of circles.

It can also be judged according to the weight of the turtle, generally the weight of the first-year-old turtle is about 15 grams, the weight of the second-year turtle is about 50 grams, the weight of the third-year turtle is about 100 grams, the weight of the fourth-year turtle is about 200 grams, and the weight of the fifth-year turtle is about 250 grams.

It can also be judged according to the ratio of the head and body of the Brazilian turtle, when the length of the dorsal carapace of the Brazilian turtle is less than 5 cm, the Brazilian turtle is about 1 year old at this time, if it is about 8 cm long, then the age of the Brazilian turtle is about 2 years old, if it is 15 cm and above, it is an adult turtle, and the adult turtle is not easy to judge, because the shell of the Brazilian turtle basically stops growing after it becomes an adult.

To see how old the Brazilian turtle is, you can count the circular lines on its abdominal spots. Moreover, there are many concentric rings on the Brazilian tortoiseshell, and this ring pattern represents a year, and the number of rings is increased by one is its age. Usually about five or six centimeters of Brazilian tortoises, about one year old, ten centimeters of Brazilian tortoises up to three years old.

: Generally, the length of the dorsal armor is less than 5-6cm, and the age is about 1 year old; dorsal carapace 6-10 cm long, 1 to 3 years old; dorsal carapace 10-18 cm 3 years old; Most of the turtles with dorsal carapaces of 17 cm or more are adults, and it is not easy to judge the age at this stage because the adult turtles have stopped growing, so it is impossible to extrapolate backwards.

The Brazilian turtle should be an adult in one year, and its age can be judged by the patterns on its body.

.Identification by hand feel. First of all, we have to touch it with our hands to feel the feel of the fabric, in general, no fiber has been added.

2.By observing the wrinkles and surface gloss. There is no bright light on the surface of the cotton fabric, so you can look at the light to see if there is any reflection. Other than that.

3.Identified by combustion. If conditions permit, you can also remove a small piece of fabric from the cotton cloth and try it with fire, after the cotton cloth is burned.

4.Distinguish by listening to sounds. The fibers of cotton cloth are relatively coarse, and cloth sellers usually cut the cloth after measuring it.

Brazilian tortoises can be seen in the following ways:

Method 1: You can put the turtle shell facing the sky to see its abdominal spots. Here, each abdominal spot of the Brazilian turtle has that kind of circular pattern, but not all of them are very regular and round.

The circular pattern of each circle represents a year (some may have two circles or none at all), and counting how many circles it has represents how old it is, so that you can estimate its age.

Method 2: You can also judge from the number of ring-like textures on its back shell. Here, each lap represents a year. Based on the number of rings you count, and then add 1 to get the age of the turtle. (This is because the turtle comes out of the shell for a year).

This method can only be used when the ring pattern on the turtle shell is very clear, so that the calculation can be relatively accurate. For those old turtles or turtles with vague and unclear concentric rings, you may only be able to estimate an approximate approximation. In addition, the Brazilian tortoise that is raised by heating cannot be used to calculate its age.

If you want to determine the age of the turtle, you can use the spots on the turtle's abdomen, the concentric rings on the turtle's back, the weight of the turtle, the length of the turtle's back carapace, etc.

To see the age of the turtle, you can turn the turtle upside down and look at the spots on its abdomen, each spot has irregular circles, and a few circles indicate how old the turtle is.

If the concentric rings on the back of the turtle are relatively clear, you can also judge the age of the turtle by the number of concentric high dust rings by Qi Chan, and the number of circles of the concentric rings plus 1 is the age of the turtle.

There is a relationship between the weight and age of a turtle, and the age of a turtle can be roughly judged by its physical constitution. About 15g is 1 year old, about 50g is 2 years old, about 100g is 3 years old, and about 200g is 4 years old, of course, these are summarized based on usual experience.

It is also possible to approximate the age of the turtle based on the length of the dorsal carapace. The length of the dorsal carapace of a 1-year-old turtle is less than 6 cm; Turtles between 1 and 3 years old have dorsal carapaces about 6 cm long and less than 10 cm long; Turtles with dorsal carapaces of more than 10 cm are adult turtles.

You can also judge the age of the turtle by the color and cleaning degree of the turtle's back lines, and the dark and clear color of the lines is older; If the texture is light and unclear, it is young.

The above method is to estimate the age of the turtle by yourself, if you want to determine the age of the turtle and know how old the turtle is, you have to find a professional.
