Introduction of the tortoise, introduction and characteristics of the tortoise

Turtles. Overview].

The turtle (chinemys reevesii), also known as the golden turtle, grass turtle, mud turtle and mountain turtle, belongs to the reptiles, turtles, turtles, turtles, and turtles subfamily in animal taxonomy, and is one of the most common turtles and turtles. Turtles are distributed in almost all parts of China, but the production in the middle and lower reaches of the Yangtze River is relatively high. It is also produced in various parts of Guangxi, especially in the southeast and south of Guangxi; It is mainly distributed in Japan and North Korea.

The tortoise shell is slightly flattened, the dorsal and ventral carapace is fixed and immobile, the dorsal carapace is 10 to 12 cm long and about 15 cm wide, with three longitudinal bulges. Yellow linear markings on the flanks of the head and neck, slightly flattened limbs, fully webbed between the fingers and toes, and claws at the ends of the toes except for the fifth hind limb.

Turtles generally live in rivers, lakes, swamps, reservoirs and mountain streams, and sometimes come ashore. In their natural environment, turtles feed on worms, snails, shrimp and small fish, as well as the stems and leaves of plants. The tortoise is an ectothermic animal that is active and feeds heavily when the temperature is above 150 degrees Celsius, and hibernates when the temperature is below 10 degrees Celsius.

Turtles are active from April to October every year, during this period, every day at sunset, turtles begin to swim in the water to feed, until dawn before the end of the day, do not stop feeding, dive into the water, and often climb ashore from 10 am to 16 pm on a sunny day, quieter than the shore to bask in the sun. From June to August, the turtle feeds during its peak season, and its food consumption gradually decreases in October, and it is in a state of hibernation from November to March.

In addition, turtles also have the following characteristics: low reproduction rate and slow growth, a turtle of about 500 grams only gains 100 grams after a year of rearing. However, turtles are more resistant to hunger, and are not easy to starve to death even if they fast for several months, and they are also resistant to disease and have a high survival rate.

Therefore, turtles are relatively easy animals to keep in captivity.

Turtles belong to the family Turtles, a species of the genus Turtles. 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.

The dorsal carapace is brown, and the males are almost black. The ventral carapace and nail bridges are brownish-yellow, and the males are dark. Each shield has large black-brown patches, and sometimes the ventral carapace is almost entirely occupied by black-brown patches, appearing brownish-yellow only at the sutures.

head olive or black-brown; There are dark trimmed yellow lines and macula on the side of the head and throat.

The skull has a bony zygomatic arch; The square yoke bone is tangent to the postorbital bone and the yoke bone; The anterior margin of the parietal bone is truncated, and the posterior end extends to the end of the epioccipital bone; posterior part of the upper occipital ridge slightly upturned; The posterior part of the squamous bone is acutely angled.

China is distributed in Hebei, Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi, Shandong, Henan, Hubei, Hunan, Hong Kong, Guangdong, Guangxi, Sichuan, Guizhou, Yunnan, Shaanxi, Gansu and Taiwan. Abroad it is distributed in Japan and North Korea.

Extended information: It often inhabits rivers, lakes and ponds, eats worms, snails, shrimp and small fish and other animals, as well as plant stems and leaves and grains. Copulation begins in late April and takes place in the evening; 5 August is the spawning period, and the annual spawning is divided.

Three or four times to complete, each time a hole to lay 5 7 eggs;

Before laying eggs, the female turtle uses her hind limbs to dig a hole in the loose soil on the sunny and shady shore, lays the eggs in the hole, and covers the loose soil on the eggs after laying. The eggs are oblong-oval, hard, grayish-white, with a diameter of 27-38 mm and 13-20 mm.

After 50 to 80 days of hatching under natural conditions, the hatchlings can live independently after hatching. The sex of the hatchlings is controlled by temperature, and the hatchlings hatchling at a temperature of 25 are males, and the hatchlings hatchlings at temperatures above 28 are females.

Turtles are a relatively common type of reptile that belongs to amphibians that breathe on their lungs and may drown if they do not surface in time. It is an omnivore and can be eaten with both meat and vegetables. When the temperature is below 10, it hibernates, lasts for 3 to 4 months, and retracts its limbs into its shell when in danger.

Turtles are more common reptiles, amphibians, swimming, but breathe through their lungs and need to surface regularly to absorb oxygen. Turtles are omnivores and can be eaten both meat and vegetables, but they should not eat too much of vegetables and fruits, which can cause diarrhea.

The appetite of the turtle changes with the temperature, and the lower the temperature, the lower the appetite. When the temperature is higher than 24, it is necessary to eat every 2 days, 20 to 24 can be fed once a week, and when the temperature is below 18, the turtle almost does not eat. In winter, when the temperature is consistently below 10, the turtle goes into hibernation, which usually lasts for 3 to 4 months.

The biggest feature of the turtle is its long lifespan, if it is well raised, it can live for a hundred years or even longer, but its growth rate is relatively slow, so the general body size is not very large, and the size of the male turtle will be larger.
