Sea turtles are large marine reptiles that appeared on Earth around the same time as the dinosaurs. Later, they migrated from the land to the sea, and survived with their armor and unique lifestyle. It can swim at speeds of up to 32 kilometers per hour in the sea, can dive to depths of 50 to 100 meters, and changes its air at the surface every ten minutes.
Although sea turtles live in the ocean, they maintain the breeding habits of their ancestors. When male and female turtles reach the age of 20 to 25, they reach "marriage age". Female tortoises will work hard to migrate to their birthplace and climb onto land to lay their eggs.
They take advantage of the darkness of the night to dig a sand pit in the sand with their forelimbs to accommodate their bodies, then climb into the sand nest, use their hind limbs to dig a 30-centimeter-deep pit under their genital holes, and then lay eggs in 2 to 5 spawns, 10 to 15 days apart, each time laying 52 to 214 eggs. Whenever the eggs are laid, it uses its hind limbs to pull sand on the pile of eggs, and uses its forelimbs to press it on the sand pile. Then climb to another place and use your claws to dig up the sand, and also press on it, so as to confuse the predators.
Sea turtles lay hundreds of eggs per stage, and the eggs are white and tough, not easy to break, and shaped like a table tennis ball.
After laying eggs, the turtle drags its tired body back to the sea. The next breeding time interval is 2 to 9 years (usually 3 years), and the eggs buried in the bunker hatch naturally by the heat of the sun and the temperature of the sand. The incubation time is about two months.
After the baby turtle broke out of its shell, it struggled to climb out of the thick sand pile, and then hurriedly crawled into the sea by relying on a large area of sea light signals. How do adult female turtles find their birthplace and climb onto their mother's birthing bed to carry on their origins? Some scientists take green sea turtles.
Experiments, it was found that it was particularly sensitive to the smell of very thin organic compounds, and could sense that there was a gas factor in its hometown that was different from that of the ocean. When baby turtles run into the ocean, they remember the smell of their hometown, and they rely on this smell to identify their directions. Some scientists have used remote control technology to study turtles by attaching transmitters and antennas to them, and they believe that turtles use star navigation to identify their route home.
Some believe that sea turtles can remember the geomagnetic direction of their birthplace and the elevation angle of their magnetic axis.
Scientists have different accounts, and this natural mystery needs to be further explored. There are not many sea turtles left on the planet. Due to the large number of indiscriminate capture, plundering of turtle eggs and destruction of the spawning and breeding environment over the years, the landing of sea turtles has decreased sharply year by year, and China has listed sea turtles as second-class protected wild animals.

Turtles crawl up to 60 meters per hour. Turtles do not crawl after being frightened and just after hibernation. Turtles don't crawl very fast, but turtles are ancient reptiles.
Turtles grow more slowly. Under normal conditions, the growth rate of turtles is about 15 grams for one-year-old turtles, 50 grams for two-year-old turtles, 100 grams for three-year-old turtles, 200 grams for four-year-old turtles, 250-350 grams for five-year-old turtles, and about 400 grams for six-year-old turtles.
Male turtles grow slowly, and the maximum sexual maturity is generally less than 750 grams.
Distribution. It is found in Japan (Honshu, Kyushu), North Korea, South Korea, Timor-Leste, Indonesia (smaller Sanda Island), Palau, and China. In China, it is distributed in Hebei, Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi, Shandong, Henan, Hubei, Hunan, Hong Kong, Guangdong, Guangxi, Sichuan, Guizhou, Yunnan, Shaanxi, Gansu, Taiwan and other places; It is distributed in all parts of Guangxi, and is more abundant in Yulin, Bobai and Yongning. It has been introduced in Europe, America and other places.

Under normal circumstances, the turtle can climb 60 meters an hour, and the size of the turtle also affects the crawling speed of the turtle, which is an amphibious carapace reptile.
There are 200,250 extant species, mostly aquatic or semi-aquatic, mostly found in tropical or near-tropical regions, but also found in temperate regions. Some turtles are terrestrial, a few are ocean-dwelling, and the rest live in freshwater. Feeds on fresh plants or small animals, or both.
Can tolerate fasting for long periods of time. Usually reproducing once a year, females lay their eggs on land, which are white, round, or elongated, and usually the female turtle burrows with her hind legs and lays her eggs in the burrows.

The tortoise moves at a speed of about 60 meters per hour.
Tortoises are ectotherms, and their lives are greatly affected by the temperature of their environment. From November to March, when the temperature is below 10, the turtle hibernates in the silt at the bottom of the pond or in the loose soil covered with straw, does not eat, does not move, and hibernates, at which point its metabolism is very slow and fragile.
It wasn't until early April, when the temperature rose above 15, that the turtles began to resume their activities and began to eat in large quantities. Therefore, there is no need to feed or change the water during hibernation. During this time, the main work is to keep warm, such as covering the space around the pool and between the pool and the walls with straw.
The second is to prevent the invasion of natural enemies and sea turtles.
Turtle belongs to the turtle family, a species of the turtle genus. Sometimes it refers specifically to the alias of turtles, grass turtles, mud turtles, etc. Taxonomically, it belongs to the class Turtle Reptilidae, the family Turtles, and is a common type of turtle.
It is an ancient reptile. It is characterized by a very hard carapace, and when attacked, it can retract its head, tail, and limbs into its shell, except for turtles and snapping turtles.
Most turtles are carnivores and feed on worms, snails, shrimp, small fish, and the stems and leaves of plants. Tortoises can be found almost everywhere in China, but they are produced in higher quantities in the middle and lower reaches of the Yangtze River. It is also produced in Guangxi and Shandong, especially in the southeast of Guangxi and the south of Guangxi.
It is mainly distributed in Japan, Brazil and North Korea.

The crawling speed of a turtle is about 60 meters per hour.
1. Turtles are ectotherms, and their lives are greatly affected by the ambient temperature. From November to March, when the temperature is below 10, the turtle lies in the silt at the bottom of the pond or lies in the loose soil covered with straw, does not eat or move, and hibernates, at which time its metabolism is very slow and weak. It is not until the beginning of April, when the temperature rises above 15, that the turtles begin to resume their activities and feed in large quantities Therefore, there is no need to feed or change the water during the hibernation period, and the main work during this period is to keep warm, such as covering the open space around the pool and between the pool and the fence with straw; The second is to prevent the invasion of natural enemies of turtles.
2. Turtles belong to the turtle family, a kind of turtle genus. Sometimes it is specifically referred to as a turtle, also known as a golden turtle, a grass turtle, a mud turtle and a mountain turtle. In terms of animal taxonomy, it belongs to the class of reptiles, turtles and turtles, and is one of the common turtles and turtles.
It is an ancient reptile that exists. It is characterized by a very strong carapace that allows the turtle to retract its head, tail and limbs into the shell when attacked (except for turtles and snapping turtles). Most turtles are carnivorous and feed on worms, snails, shrimp and small fish, as well as the stems and leaves of plants.
Turtles are found almost everywhere in China, but the production is higher in the middle and lower reaches of the Yangtze River. Guangxi, Shandong is also produced in various places, especially in the southeast of Guangxi, south of Guizhou and other places. It is mainly distributed in Japan, Brazil and North Korea.
3. The turtle egg shell is grayish-white, oval, long and wide. Under natural conditions, after 50 to 80 days of hatching, the juvenile turtle will break out of its shell. However, the natural incubation of turtle eggs is susceptible to the influence of external conditions such as temperature and light, as well as the harm of natural enemies such as snakes, rats and ants, which makes the incubation period long, and the hatching rate and survival rate are low.
In order to improve the hatching rate of turtles, artificial incubation can be used.
4. When checking the head of the turtle, you can use your thumb and index finger to buckle the back of the head when it is not paying attention, and the action should be very fast, otherwise it will be difficult to check once it is retracted into the shell. If the turtle sheds too much skin, it may be caused by a problem or unbalanced nutrition. EyesThe eyes of the turtle should be very clear and bright, if you notice that the eyes and face are swollen and more tears are formed, it means that there is a problem with the eyes, in addition to eye infection, foreign body, corneal trauma or cataract, the more common is conjunctivitis caused by vitamin A deficiency, especially during development.

The speed of a tortoise crawling is about a kilometre-hour, and the speed of a rabbit is 60 kilometre-hour, which is 1,000 times faster than a tortoise. For the sake of calculation, if we assume that the race distance is a kilometer, it will take the rabbit 72 seconds to reach its destination, while the turtle will have to climb for 20 hours!
-
Turtles are 60 meters per hour, which is 30 meters faster than ordinary ants, and their large size will affect their speed.
-
Turtles crawl up to 60 meters per hour.
-
1.Turtles can climb about 60 meters an hour.
2.The reason why it crawls slowly is partly due to its own structure that is not conducive to rapid movement, and partly because of the low level of metabolism of this animal.
3.It is worth mentioning that although the crawling speed is not fast, many terrapins swim quite quickly in the water, which also allows them to prey on some fish and other aquatic animals.

The distance that tortoises crawl per hour is: 4 5 * 1 6 = 1 30 km
The time it takes for a tortoise to climb one km is 1 km 1 30 km hr) = 30 hours.
-
<> turtle can't climb more than 200 meters per hour, 200 decimeters is more than enough, in fact, under normal circumstances, it can climb about 60 meters an hour. There are two main reasons for the slow movement of the turtle, one is that its body structure does not allow it to move quickly, and the other is that its own metabolism is relatively low, so it is difficult to run fast. However, turtles are still very fast in the water and are good at swimming.

3 meters. The tortoise crawls three-quarters of an hour and the tortoise crawls 3 meters per hour. Because the mold spike oak according to the title of the Liedan side formula: 3 2 (m/h) 1 2 (h) = 3 m, so the tortoise crawls 3 m in 1 h.
1 kWh is equal to joules.

Sloth. It is the only wild animal with plants on it.
Although it has legs, it cannot walk, relying on its forelimbs to drag its body forward. So it takes 1 month to move a distance of 2 km. The speed of escape is no more than a meter second, and it climbs kilometers per hour. >>>More
This is of course true, snails can climb 50 decimeters in an hour, which means that they can climb 5 meters in an hour.
