How does the Chinese Juvenile Encyclopedia introduce squirrels? Hurry, Hurry, Hurry!!

1. Squirrels, belonging to the rodent squirrel family, generally refer to a large class of rodents with fluffy long hairs on their tails, there are about 58 genera and 285 species, distributed throughout all continents outside Antarctica (introduced species in Oceania).

2. Contrary to most people's impressions, the squirrel that lives in trees, has a big fluffy tail, and can hold a pine cone to gnaw on is actually just a small branch of the squirrel family.

3. From the snow-capped mountains at an altitude of more than 6,000 meters to the tropical islands in the Pacific Ocean, from the western hemisphere to the eastern hemisphere, except for the areas with extremely harsh climate and extremely simple vegetation in the deserts close to the polar regions or the driest deserts, the species of the squirrel family are active in various terrestrial habitats, and some also play an extremely important role in the ecosystem.

4. Squirrels are mainly distributed in coniferous forests or mixed coniferous and broad-leaved forests composed of Pinus, larix and Picea species. Due to the relative abundance and stability of food**, squirrels can maintain high population densities in mixed coniferous and broad-leaved forests, and can use small woodlands in suburban or even urban areas to become companion animals.

5. It is widely distributed in the temperate and cold temperate forest ecosystems of the Palearctic boundary, from Iberia and Great Britain in the west, to Kamchatka Peninsula, Sakhalin Island in Russia and Hokkaido in Japan in the east, and to the Mediterranean, the Black Sea, northern Mongolia, and the northwest and northeast regions of China in the south.

Squirrels are a family in the mammalian rodents, which includes the subfamily Squirrel and the African ground squirrel subfamily, characterized by a long, fluffy tail and a well-proportioned and flexible body. According to the living environment, the squirrel family is divided into tree squirrels, ground squirrels and stone squirrels. Other animals that are closely related to each other are collectively known as the squirrel suborder.

There are nearly 35 genera and 212 species in the world, and there are 11 genera and 24 species in China, among which two species are endemic to China, the rock squirrel and the laterally striated rock squirrel.

The squirrel (sciuridae) is a family of mammalian rodents, which includes the subfamily Squirrel and the African ground squirrel subfamily, characterized by a long, hairy tail. Other animals that are closely related to each other are collectively known as the squirrel suborder. Squirrels are small, herbivorous and feed mainly on seeds and nuts, with some species feeding on insects and vegetables, and some tropical species migrating to hunt insects.

Squirrels are native to the northeast, northwest and Europe of China, and are distributed in other parts of the world except Oceania and Antarctica.

Personality: Gentle, cute, well-behaved, tame, likable, very hardworking, clean, intelligent, dexterous, and does not like to go into the water. Lifespan:

The current varieties are generally 4-10 years old, and in special cases may be less than four years. Distribution: Squirrels have a wide range of distribution and can be found throughout cold temperate forest areas.

Squirrel habits: The ears and tail hairs of squirrels are particularly long, which can adapt to life in trees; They use claws and tails like long hooks to hang upside down from tree branches. At dawn and evening, they also leave the trees and go to the ground to hunt.

Reproduction: The squirrel has a strong ability to give birth to children, and like other rodents, it has the characteristics of early maturity and fast reproduction. The squirrel has an extremely well-developed sense of smell, and it can accurately distinguish the emptiness of pine seed kernels.

1. Squirrels are generally small, and their body size can be as small as 7 10 cm long and about 100 grams in weight in African pygmy squirrels, and as large as 53 73 cm in length and about 5 8 kg in weight of marmots (marmots). The squirrel has no skin wings between the front and rear limbs, and the limbs are strong, with sharp claws on the toes, hooked claws, and the females are slightly heavier than the males. The genera and squirrel genera have buccal pouches on the inside of their cheeks, which can store a lot of food.

Squirrels are typical arboreal creatures with slender bodies that appear particularly small against the soft dense long hair. The body length is 20 28 cm, the tail length is 15 24 cm, and the weight is 300 400 grams.

It is distributed from the Russian Far East, Japan, Korea, and northern Mongolia to the west to Western Europe.

In the taiga, squirrels are not abundant every year, and the number of squirrels is transferred by the number of seeds of conifers in winter, because its diet is mainly seeds and fruits, and seeds sometimes account for more than 97%.
