What are the dorsal carapaces of the grass turtle, the dorsal carapace and the ventral carapace of t

Under normal circumstances, it is generally 13 pieces, but individual ones are not necessarily 13 pieces, such as 12 pieces of Chinese tortoise.

<> tortoise's dorsal and ventral carapaces are its tail keel and ribs, respectively. The shell is a part of its bones and is the result of biological evolution. The shell protects the turtle from predators, while the tortoise can also shrink its limbs and head and tail into the shell so that it cannot be bitten.

The shell of the turtle is renewed as it grows, that is, the shell is replaced, because the shell restricts the growth of the turtle and needs to be replaced with a larger shell to grow.

The darker the color, the clearer the grain, the older it is, and the other way it is tender, if it is the actual age, it is difficult to judge.

Methods for identifying the age of a tortoise. It is to look at the lines on the carapace on the back of the turtle, that is, the number of circles, there are circles on each carapace, and the number of circles represents the age. The more laps you have, the older you get.

The age of the turtle is generally calculated by the number of concentric rings on the shield on the back of the turtle, and each circle represents a growth cycle, that is, one year.

The number of concentric rings on the shield and the rubber sheet, and then add 1 (the broken shell is born for one year) is the age of the turtle. This method can only be calculated accurately when the concentric rings of the tortoise carapace are clear, and the approximate age of the old turtle or the concentric rings are blurred, can only be estimated.

The Basics:

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.

This does not belong to the rot armor. This is a superficial fungal infection, initially. Fungal infections and rotting nails are actually quite easy to distinguish.

1.Smell, rot is generally believed to be caused by anaerobic bacteria invading the bone plate, anaerobic bacteria will cause the soft banquet tissue between the bone plate and the shield plate to be destroyed at the same time, and the damaged soft tissue will release various amines and ammonia after protein deterioration. As a result, the affected area of the turtle with rotting shells will have a characteristic foul smell, similar to the smell of rotting fish and old aqua toilets.

The fungus erodes the stratum corneum of the shield and generally does not have a peculiar smell.

2.The shape of the affected area, the carapace of fungal infection, generally presents white spots or mottled dots, flakes of the stratum corneum peeling, the location of the appearance is generally in the stratum corneum, very rare cases will be because the stratum corneum is damaged after exposing the underlying bone plate, the bone plate loses the protection of the stratum corneum and gradually atrophies or proliferates to form a developmental deformity. The armor does not erode the cuticle, so the shield is basically intact, and only after the soft tissue under the shield is hollowed out will warping or hollowing occur.

Is the grass tortoiseshell so rotten and bright?

This situation does not belong to nail rot, it should be that the turtle has been out of the water for too long, causing the dry hall of the lead song to dry up like this, hurry up and give it a basin of water bubbles.

Generally, this is a rotten armor, so it needs to be ** in time, so that this small animal can grow better.

Hello, the grass tortoise back carapace is red and black because of the body caused by nail rot, nail rot is a disease caused by the influence of water quality, the need for pants to swim to trap water for three days in use, ** and treatment methods are: Ensure that the titer before feeding temperature is 25-30 degrees. It is best to use a ceramic heater or infrared heating lamp for reptiles to heat the air in the breeding box, avoid rabbits with high temperature and humidity caused by bacteria, fungi, viruses, mycoplasma, chlamydia and other pathogenic microorganisms breeding containers cleaning and disinfection It is recommended to dry raise, bathe 2-3 times a day, each bath time is 10-15 minutes or dry and water alternately when feeding dry raising, the affected area is smeared with 5% povidone-iodine solution, multiple times a day, when water raising, you can use 5% Solution:

Water = 1: 500-1000 ratio of the liquid medicine soaked turtle turtle Hu penitential skin is serious or due to rotten skinIf you refuse to eat, it is recommended to take oral antibiotics (cefraj, etc.) in combination**. Do you have any questions that I would like to answer for you?

The details are as follows:Hawksbill turtles belong to the class Reptiles, marine animals of the turtle family, generally move in waters above the sea depth, have strong activity ability, and swim faster. Its dorsal carapace scales have regular radial patterns, mixed yellow-brown and black.

Hawksbill turtle (scientific name: eretmochelysimbricata): a marine animal belonging to the family Reptiles, the family of sea turtles.

The dorsal carapace is centimeter long and weighs 35-127 kg. Generally, they are active in waters above the sea depth, and their mobility is strong and their swimming speed is fast. The main living areas are shallow lagoons and coral reef areas, and food includes sponges, jellyfish, anemones, shrimp, crabs, and shellfish, as well as fish and seaweed.

It is distributed in a wide range of seas, and is mainly found in the tropical areas of the Atlantic Ocean and the Pacific Ocean.

Due to the overexploitation of the nesting beaches where hawksbill turtles lay eggs and nests, the habitat of the nest has been degraded, and the populations of both larvae and adults in the main marine areas have been greatly reduced. Listed in the IUCN criteria Critically Critical (CR); It was included in the first level of China's "List of Wild Animals under National Key Protection" (February 5, 2021).
