Secondly, turtles, like people, have different body colors.

Leg color: semi-red and yellow scales, semi-blue and yellow scales, semi-brown and yellow scales, etc.

Shell color: bright yellow shell, orange shell, blue-yellow shell, red-yellow shell, crimson shell, etc.

Head color: generally, it is yellow in the front section and blue in the back section, some are overall bluish yellow and some are overall bright yellow.

But in general, the wild throats that have just come out of the water are all blue and yellow (this is the picture)

Claw color: generally refers to brown roots, translucent waxy yellow fingertips, and some whole translucent waxy yellow.

Tail color: generally dark brown, with two yellow or red-yellow lateral lines, but some are white-yellow or red-yellow.

Pupils: generally, there are those with lateral lines and those without lateral lines (it seems that the pupils are very large), and a clear eye film is wrapped outside.

Next, I will focus on the influence of feeding quality on the body color of yellow throat. Yellow throat, or other turtles, or even people, their body color (called skin color) is directly related to their health.

Contact. The same yellow throat, the turtle in sub-health state is definitely not as good as the healthy yellow throat. For example, the yellow throat in the rotting state of skin and nails, or the infection of respiratory and digestive systems, its body color will be darker than that of turtles in normal health. Especially for young turtles, the shell is thin and the pigment deposition is unstable, which is more contrasted with the adult larynx. And good water quality (clear, flowing weak alkaline water, no toxic organic matter), large enough feeding space, proper illumination, reasonable food and proper vitamin supplement. These are all necessary conditions for raising a healthy yellow-throated turtle. For example, the cleanliness of the air directly affects our health. Then there is the water turtle, an animal that has been dealing with water for a long time. As the name implies, water quality has the greatest influence on a water turtle. A jar of good water can promote turtle's metabolism and appetite, and avoid diseases such as rotten skin, rotten nails and white eyes. How to raise a tank of water, I have detailed instructions in other posts, so I won't go into details here. Sufficient feeding space can increase turtle's exercise, promote appetite and avoid muscle atrophy and body size limitation. Increasing the shelter space can make the tortoise hide quickly when it is frightened or the direct sunlight is too strong, so that the tortoise can maintain a good mental state for a long time. Proper light is essential for turtle to synthesize calcium, maintain skin health and promote metabolism (there are many good posts explaining it, so I won't go into details here). Reasonable food, I don't need to go into details, is nothing more than food diversification and reasonable feeding. Among them, carbohydrate supplement is very important for intestinal conditioning, and feed is recommended here. Appropriate vitamin supplementation is essential, which can improve the comprehensive immunity of soft-shelled turtle and prevent many diseases, such as blindness, dermatosis and fungal infection. Here we recommend a reptile multivitamin, which can be made by American or Taiwan Province brands. As for the prevention and treatment of diseases, I won't go into details. Only a healthy yellow throat can present the most beautiful body color, and long-term use of correct feeding methods is the premise to ensure health. As for some minor diseases, we can completely cure them through diet therapy and water quality control, such as skin diseases such as rotten skin and nails, vitamin deficiency such as muscle weakness and white eyes. It's a three-point poison Use it as little as possible unless absolutely necessary. Of course, all the above are based on the experience of raising in a small family environment. As for the big pond culture, there is no such condition to practice, please ask experienced friends to supplement it. But I believe that the best environment is the most suitable environment for nature.

Having said that, I just want to tell you that raising a beautiful yellow throat is not only by "keeping it in a light-colored container or a yellow container", nor by "eating more shrimps to accumulate pigments", nor by "exposure to the sun at the limit water level". Of course, when the yellow throat is raised in a clear light container, its body color will gradually fade, on the contrary, it will gradually deepen in the dark environment of muddy water, indicating that its body color is affected by certain environmental factors. However, personally, these are not the body colors that a normal yellow throat should have. How to keep the color of wild throat full of game for a long time in artificial environment is a problem that yellow throat lovers should study and ponder. A friend said to me, "Put your yellow throat in a black container for a while to see if it will turn black." "Dare to expose your yellow throat in the sun for a while to see if the color on your head will turn black." My answer is: "You shut yourself in a dark room for a week to see if it will turn white." "You expose yourself to the sun all day to see if it will turn black." The strange color raised by incorrect feeding methods does not represent the healthy body color of yellow throat, but is the performance of sub-health, which is not comparable and cannot be used as a standard to measure the normal body color of healthy yellow throat. Comparing this abnormal body color with healthy yellow throat with normal body color, it is concluded that "body color is not affected by genetic factors, but only by environment" and "yellow throat is artificially made".
