Why does a turtle have a shell and what does a turtle s shell look like when it falls off?

It is said that once upon a time, the turtle had no shell, and it was very proud to be counted among the animals that it ran fast.

Once, the United Nations of the Forest held a running conference, inviting all the fastest runners in the same animal country to participate in the race, which was scheduled to be held on the Turtle Day of the Ox Moon in the Year of the Elephant.

On the day of the competition, the Turtle Nation sent long-legged turtles that had won many championships in each competition; On behalf of the rabbit country is the short-tailed rabbit, don't look at it looks thin and small, it can jump up fast, and it has won many battles in the race of the rabbit country. Naturally, after a battle between the dragons and the tigers, as expected, the final was played between the country of turtles and rabbits.

Although the rabbit country won the right to the finals, they are very modest, they do not relax at all, they are still stepping up their training, and they are determined to become the fastest in the world! The Turtle Country is also busy, but they are busy drinking celebratory wine, thinking that the victory is decided, and the gold medal belongs to the Turtle Country.

The finals began. "Smack", only to hear the referee's gunshot, the short-tailed rabbit and the long-legged turtle, a bullet like a disemboweled, a flying arrow like a string, "swish, swish" out.

Running and running, the tortoise was physically exhausted due to lack of serious training, and gradually fell behind the rabbit. The turtle was in a hurry, and the four long legs were pounding vigorously. After running for a while, I suddenly felt dizzy, it turned out that I was drunk, and the turtle couldn't care so much, so I closed my eyes and ran forward desperately.

At this time, an unexpected accident appeared: a clay pot with a pattern suddenly rolled out of the roadside, and the turtle was confused, and just plunged into ......

When the turtle woke up, it was pitch black in front of him, and he couldn't see his five fingers, "Where am I?" "The turtle felt inexplicable. After some struggle, the turtle finally stretched its head and four long legs out of the jar, and crawled towards the finish line with the clay pot, probably wanting to be the runner-up!

Although the turtle lost the gold medal, it carried a clay pot with a pattern. From then on, the turtle had a shell.

To protect yourself. It's the same as why hedgehogs have thorns. Simple, right.

Evolved along the belt.

There's a new shell inside.

The shedding of the tortoise's shell is not about shedding the entire shell and replacing it with a new carapace. It's the cuticle on its back and belly.

The substance falls off one by one, it is a thin layer, but when you touch it with your hand, it feels like a fingernail, and it also has a certain hardness. The large ones are the size of a coin, and the small ones are like a fingernail.

Turtle precautions.

The first thing to do in turtle breeding is to choose the right breeding location, followed by to ensure that the water quality is fresh. Pay attention to balanced nutrition in feeding, and do not feed too much.

Secondly, in the selection of small turtles, everyone should choose small turtles with good breeds, lively and healthy. Don't choose a small turtle of an out-of-town breed for the sake of a momentary novelty. Baby turtles purchased from other places may be extremely unsuitable for the local breeding environment, which is not conducive to the breeding of baby turtles.

Summary. Hello dear, the shell of the turtle is made up of rows of firmly attached bony plates, which are then covered with some horny plates or shields, and the dorsal dome carapace is connected to the flat ventral carapace below by a bony bridge. The resulting shell wraps around the shoulders and hips, but the head, neck, and front of the front legs, as well as the tail and the back of the hind limbs, are all open, so they can stretch freely, except for the turtles, do you see anything else that needs help?

The whole shell of the turtle why this.

How to raise turtles.

1. Feeding containers.

Storage boxes, logistics boxes, fish tanks, etc. can all be used to raise turtles. Before feeding, it should be disinfected with light salt water, potassium permanganate dilution, etc., and rinsed with water repeatedly after disinfection. The height of the container should not be too shallow, and the inner wall should not be too rough, because the black chain bird turtle has a strong climbing ability, and a container that is too shallow and too rough can easily allow it to escape.

The feeding density should not be too large, too large density can easily cause turtles to fight and grab food, bringing the risk of tail breaking.

2. Water for feeding.

Turtles can be kept with tap water that has been dried in the sun for more than two days, well water, etc. After drying, it can remove harmful substances such as chlorine in the water, and at the same time can promote the reproduction of algae and probiotics in the water. Turtles are more stressful, and it takes a long time to adapt to the water quality after arriving in a new environment, and the direct use of tap water will cause turtles to get sick, so do not be greedy for convenience and directly use tap water to raise turtles.

The water level of the turtle is better to be twice the length of the tortoise's back carapace to 1 time earlier, so that the turtle can stick its head out of the water at any time to breathe. Every time you change the water, you can change about half of the old water, pay attention to the temperature of the new water added should be consistent with the old water, and the water change time should be carried out every day when the temperature is high, so as not to cause the turtle to catch a cold. Filters can also be used to purify water quality, enhance water circulation, and reduce the frequency of water changes.

3. Feeding temperature.

The optimal growing temperature for turtles is between 25 and 30 degrees, with too high temperatures causing heat stroke and too low temperatures causing turtles to stop feeding. In summer, turtles should be raised to prevent heatstroke and cool down to avoid turtles from heat stroke and die.

Fourth, light. When raising turtles, it is necessary to set up a gentle slope and exposed sundeck in the water, so that the turtles can climb out of the water at any time to rest and bask their backs. Receiving proper light every day is of great significance to turtles, which can not only promote the synthesis of vitamin D3 in their bodies to speed up calcium absorption, but also effectively prevent the occurrence of various diseases.

Also, when sunbathing turtles in the summer, avoid the midday hours to avoid excessive temperatures.

5. Food. Turtles can be raised using a variety of water turtle larvae food, or they can be fed fish and shrimp meat. When feeding fish and shrimp, cut the food into appropriate shapes, too large food is not conducive to the turtle to eat, and pay attention to clean up the hard residue in the food to avoid scratching the turtle's gastrointestinal esophagus.

It can be fed once a day, and the amount of each feeding is preferably so that the turtle can eat it within 5 minutes. Do not overfeed food, first, overfeeding can easily cause indigestion and rapid growth of turtles, resulting in gastrointestinal diseases, growth deformities, etc.; Second, overfeeding is easy to produce too much food residue, resulting in poor water quality.

The tortoise shell rots because of nail rot, and the shell needs to grow during the growth of the turtle, so the old shell will fall off like scales, so the tortoise shell can grow back to its original state.

** method of nail rot disease:

Dry rearing in the sun. Slight rotting armor is easy to heal, except for the diseased turtle in the special location of the rot, under the action of sunlight, the carapace of the wound will be warped, and the white rot will fall off on its own. If the back armor is rotten, then feed it in shallow water, and basically do not need to use medicine.

The abdominal armor is injured, all dry and nourishing, and the water is regularly entered and eaten every day.

Moderately rotten, need to use scissors to pick up and cut off the injured tortoise shell after the sun, and then use a toothpick that is not sharp to remove the rotten part of the sun, until you see the new muscles, the important thing is not to make the tortoise bleed, causing 2 injuries. Then clean and disinfect with hydrogen peroxide, apply potassium permanganate powder, and can also be sealed with petroleum jelly and protected by band-aids.
