Turtles cannot climb trees.
Turtles’ habitat:
Turtles generally live in streams, rivers, lakes, swamps, reservoirs and mountain streams, sometimes Also go ashore for activities. In the natural environment, turtles feed on worms, snails, shrimps and small fish, as well as the stems and leaves of plants. The turtle is a cold-blooded animal. In winter, or when the temperature is low for a long time, the turtle will enter hibernation. Different types of turtles have different temperatures at which they start to hibernate, but they are usually between 10 and 10 16℃. At this time, the turtle will stay in its shell for a long time, almost inactive. At the same time, its breathing rate will decrease, its body temperature will decrease, its blood circulation and metabolism will slow down, and the nutrients it consumes will also decrease relatively. This state is similar to sleep, but it is a deep sleep that lasts for several months, and may even present a slight state of paralysis.
In addition, turtles also have the following characteristics: low reproduction rate and slow growth. A turtle weighing about 500 grams only gains about 100 grams in one year of feeding. However, turtles have strong hunger tolerance and are not easily starved to death even if they have been without food for several months. They also have strong disease resistance and a high survival rate. Therefore, turtles are the reptiles that are easier to raise in captivity and are also more popular pets.
6 Distribution areas
Edit
Turtles are distributed in most parts of the world and have existed in the same form at least 200 million years ago. There are 200 to 250 species in existence, most of which are aquatic or semi-aquatic. Most are distributed in tropical or near-tropical areas, and many are also found in temperate areas. Some turtles are terrestrial, a few live in the ocean, and the rest live in freshwater. Feed on tender plants or small animals, or both. Fasting can be tolerated for long periods of time. They usually breed once a year. The female lays eggs on land. The eggs are white, round or elongated. Usually the female turtle digs a hole with her hind legs and lays the eggs in the hole.
Except for the northeastern and northwest provinces (autonomous regions) and the Tibet Autonomous Region, which have not been reported, it is distributed in other places in China, but the output in the provinces in the middle and lower reaches of the Yangtze River is higher.
Turtles are distributed in Japan and North Korea abroad; turtles have a wide distribution range and are very adaptable. However, due to serious environmental pollution, habitat destruction, and man-made excessive predation, it is now rare in our country and is in an endangered state. It can be artificially reproduced in large numbers.
Turtles provide humans with meat, eggs and shells. Some species are kept as pets. In the UK, non-turtles are usually called tortoises, while in the United States some edible turtles are called terrapins. Extant species worldwide are divided into two suborders. One type of turtle, the Pleurodira, has its neck bent to one side to retract its head into the shell, while the other, the Cryptodira, has its head and neck retracted into the shell together. Side-necked turtles are now only found in South America, Africa, Madagascar, Australia, New Guinea and neighboring islands. In contrast, cryptonecked turtles are found on all continents except Australia, and include about four-fifths of extant turtle species.
The largest family of the suborder Emydidae is the Emydidae, which includes about 1/3 of the existing species, and its geographical distribution range is equivalent to that of all suborders. Mostly distributed in the eastern half of the United States, they are mostly aquatic or semi-aquatic. Next is the turtle family (Testudinidae), which has about half the species of the terrapin family. The dull, slow tortoise of the fable belongs to a widespread group of tortoises, the large species of which are found only in the Galapagos and other islands. Other families of hidden-necked turtles include Kinosternidae and Cheloniidae, which are found in warm seawater all over the world; and snapping turtles (Chelydridae), which are large and aggressive and are common in North America.
Species of the side-necked turtle suborder are now only distributed in the southern hemisphere continent, including about 20% of the existing turtle species. Among them, there are two existing families: Chelidae, named for its long head and neck, and Pelomedusidae, from which the name of this suborder comes.
