Why do turtles live long and why can turtles live for how long

Because turtles have a slow metabolism, but not all turtles live long. The normal lifespan of a Brazilian turtle may be about 80, I don't know if it's right, hehe. Our Chinese grass turtle (tortoise) has lived a relatively long time.

Because tortoises are hungry, drought-tolerant, and lazy, they live for a long time

Because tortoises are hungry, drought-tolerant, and lazy!

Generally around 15 years! It seems that there is a record of living for more than 100 years now! Different varieties have different lifespans.

Why can turtles live for how long

Turtles are long-lived animals, according to statistics, turtles can live for more than 150 years, and tortoises can even live for more than 200 years. So, why do turtles live so long? The following is elaborated from several aspects.

1. Low metabolic rate

The body of a turtle has a very low metabolic rate, which means that their metabolism is slow. Since metabolism can release free radicals, which can damage cells and DNA, which can accelerate aging. Therefore, the turtle has a slow metabolic rate which is one reason for its longevity.

One of the turtles' worst enemies in nature is birds, as they are able to catch turtles in slow motion. Despite its slow speed, tortoises do not need a lot of food to maintain their bodily functions because their bodies have little to no process of decomposition and consumption.

2. Strong defense mechanism

Turtles have very strong defense mechanisms. They have a hard shell that protects themselves from predators. If attacked, the turtle can gain further protection by retracting its head, legs, and tail.

In addition, turtles have strong immunity. Studies have shown that their blood contains a protein called turtle blood, which has antibacterial, antiviral, and anticancer effects. This is one of the reasons why tortoises have been able to live so long.

3. Rolling reproduction

The longevity of a turtle is related to the way it reproduces. Most tortoises are oviparous and take a considerable amount of time to give birth to their offspring. The tortoise forces its own intergenerational continuation to be longer, greatly increasing its life cycle.

In addition, female tortoises need to eat a lot of food in order to lay a sufficient number of eggs, which may also explain why people are impressed by the long life span of the tortoise.

4. Genes

The DNA of turtles, like the DNA of other animals, is susceptible to aging and decay. However, according to research, the genetic makeup of turtles is significantly different from that of other birds, mammals, and other animals. It was found that the genome in the turtle has a strong anti-aging ability, which is one of the reasons why the turtle can live a long life.

The above is the reason why turtles can live for so long, low metabolic rate, strong defense mechanism, reproductive methods, genes and other aspects of excellent performance, making turtles an outstanding representative of long-lived animals. The remainder is late.

Analysis: 1) The tortoise's body is contained in a bony carapace, and the surface of the carapace is covered with keratin sheets. No matter how much mechanical pressure from the outside world and how vicious the enemy, as long as the turtle shrinks its toes, it will be safe and sound.

Therefore, although people are reluctant to be a "turtle with a shrunken head", the head of the turtle is an excellent way to protect themselves.

2) The ability of turtles to adapt to the external environment is particularly strong and widely distributed. In China, except for the northeast and northwest provinces and autonomous regions, which have not been reported, other provinces in the country are distributed. Whether it is land, rivers, mountains, plains, deserts, or silt, there are traces of it.

This is because the turtle has a water reservoir (attached to the bladder) and an auxiliary respirator (an auxiliary respirator in the throat and a respiratory sac on both sides of the cloaca).

3) Turtles have a wide range of diets and are resistant to hunger. The "recipes" of turtles are: fish, meat, earthworms, snails, animal blood clots, animal liver, melons and vegetables, insects, etc.

Whether it's animal food or plant food, turtles can eat with relish. In addition, turtles can go without eating or drinking for years or even centuries. It has been found that the abdominal carapace of the turtle is used to store food.

4) Turtles are not very active and tend to enter a dormant state. When there is danger from the outside world, ordinary animals are bound to flee in a hurry, but turtles are not. It just shrank its head unhurriedly.

When the external environment deteriorates, especially when the temperature is too high or too low, the turtle goes into hibernation. The turtle's "adaptation to change" behavior reduces energy expenditure and avoids some accidental deaths.

5) Turtles rarely get sick. At present, only a few diseases have been found in captivity, which cause turtles to suffer from poor technology. In the wild, tortoises rarely get sick.

There are two reasons for this: first, turtles have the habit of basking in the sun, which can kill some pathogens that may cause disease; Second, the tortoise's lymphatic system is particularly developed and its immunity is extremely strong.

In addition, some people have found through research that the tortoise's cell reproduction generations are particularly large, the tortoise's heart beats slowly during exercise, and the isolated heart of the turtle can beat for two days, which is undoubtedly the "trick" of the tortoise's longevity.
