What exactly is a turtle shell? Once the tortoise loses its shell, can it survive? The tortoise is a small animal full of mystery. In ancient times, many images of spirit beasts were related to turtles.

At first, experts thought that the ancestors of turtles were half-toothed turtles evolved from their ancestors, but modern turtles did not have front teeth, which was not quite consistent. Later, experts regarded Zhengnan turtle as the ancestor of turtle, but after the occurrence of molecular structure biology, they confirmed that the ancestors of turtle and Hubei fish and their birds were the same ancestor, while the ancestors of Hubei fish and their birds were not separated in Permian, but Permian was just the period of Zhengnan turtle's daily life, so they inferred.

The beginning of the turtle is often not found, which is closely related to the growth of ancient times. During the Permian period, there was a deep sea between Laocrow and Gondwana, called Tethys Sea, and the top predator of Tethys Sea was Lei Long. Lei Long has strong bite force and faster speed, so many creatures have stepped into the road of overlapping armor in order to better avoid disasters, which prompted many overlapping armored creatures to occur at the same time. Because of its long history, it is difficult for people to clearly understand the evolutionary path of the turtle. But most of the overlapping creatures gradually declined in the later struggle for existence. At this stage, the turtle became the only mammal with a closed hard shell on the earth.

Hard shell is the representative feature of tortoise and a powerful protective weapon for tortoise. Experiments show that an adult male standing on a turtle with a big slap on his face with one foot is not only not easy to crush the turtle shell, but also not easy to cause all the damage to the turtle at all.

John sampson, a master photographer, has shot such scenes before. A lion was walking on the grassland and found a turtle. He opened his mouth and bit it. As a result, he turned around and bit left and right, indicating that he did not move. Finally, he had to leave. An adult lioness can bite about 1000 kg, in other words, the tortoise shell can bear the working pressure of 1000 kg, which is really not simple. Tortoise shell maintains the tortoise's soft human body, so if the tortoise has no tortoise shell, can it live any longer? To master this problem, we need to know what a turtle shell is.

In some cartoons, little turtles can come out of their shells, but this is not true. In the process of realization, the tortoise can't shell itself, and everyone can't pull it out of the shell intact, because the shell is not only a defensive weapon of the tortoise, it is a whole with the tortoise.

Tortoise shell can be divided into two parts: the carapace, including the tortoise's spine, and the carapace, including the tortoise's ribs and breastplate bones. The two sides of the carapace and the carapace are connected together to form an arc structure. What will happen if we remove the tortoise's shell? Removing the tortoise's shell is equivalent to removing the tortoise's spine. Obviously, mammals without backbones will have any adverse effects.

Similarly, if the tortoise's abdominal armor is removed, it is equivalent to removing the tortoise's ribs and breastplate bones. If all the tortoise shells are removed, the tortoise's human body suddenly loses its support point and collapses to the ground.

In fact, the tortoise will die when it is forcibly shelled. Because the tortoise shell and the tortoise are integrated, forcibly shelling will cause the tortoise to tear the flesh, and it will kill the internal bleeding at once. Therefore, the tortoise can't live without its shell. If its shell is damaged, its life will end. This is why little turtles with patterns on their shells can't survive for a long time.
