What parts of the squirrel have biomimicry

The parachute was invented using the aerodynamics of the tail.

The tail of a squirrel has biomimetic significance.

Biomimicry refers to the science of human beings imitating biological functions to invent and create. It is a new marginal discipline. The study of the structure, function and working principles of living organisms and the transplantation of these principles into man-made engineering techniques.

The advent of this discipline has greatly broadened the technological horizons of mankind, shown great development potential, and is the crystallization of human wisdom.

Biomimicry is a special ability to imitate organisms, using the structural and functional principles of organisms to develop machinery or various new technologies.

The term biomimicry was coined in 1960 by the American Steele based on the Latin word "bios (meaning way of life)" and the ending "nlc ('has ......nature's meaning)" The term has only been in use since about 1961. Biomimicry is a discipline that aims to achieve and effectively apply biological functions in engineering to the extent that certain living organisms have so far been superior to those of any man-made machine.

For example, the structure and function of living organisms such as information reception (sensory function), information transmission (neural function), and automatic control systems have greatly inspired the mechanical design. Biomimetic examples can be cited, such as the application of the dolphin's body shape or structure (which allows the surface of the body to be free of turbulence when swimming) to submarine design principles.

For example, flies are transmitters of bacteria and are generally classified as pests, but the wings of flies are natural navigators. Moreover, its eyes are a kind of "compound eye", which is composed of more than 3,000 small eyes, and people imitate it to make a "fly's eye lens". The "fly's eye lens" is a new type of optical component, and it has many uses.

The "fly's eye lens" is made of hundreds or thousands of small lenses neatly arranged and combined, and it can be used as a lens to make a "fly's eye camera", which can take thousands of identical photos at a time. These cameras have been used for printing plates and for mass copying of tiny circuits of electronic computers, greatly improving ergonomics and quality.

Biomimicry is also considered to be a discipline closely related to cybernetics, which is mainly a discipline that compares life phenomena with mechanical principles for study and interpretation.

The squirrel is a typical animal in the cold temperate coniferous forests and mixed forests, with a slender and light body, a body length of 18 26 cm, a weight of about 350 grams, and the weight of females is higher than that of males. The squirrel has strong limbs, the forelimbs are shorter than the hind limbs, the toes have sharp claws, and the claws are hooked at the ends. The ear shell is well-developed, blackish-gray, and reaches the eye when folded forward, and there is a tuft of long black hair at the end of the ear in winter.

The snout, cheeks, and chin are the same color as the back, with a bluish-gray tinge. The abdomen is white from the back of the chin to the base of the tail and the inside of the limbs. The tail is long and thick, more than 2 3 of body length, densely hairy and fluffy, brownish-black.

Appearance: Squirrels are usually medium in size and are typical animals in cold temperate coniferous forests and mixed forests. The squirrel has 5 maxillary molars and 4 lower jaw molars, and the number of upper and lower jaw molars varies.

There are no leather wings between the anterior and hind limbs. The limbs are strong, the toes have sharp claws, the claw ends are hooked, and the weight is usually around 350 grams, and the female is slightly heavier than the male. The squirrel has a dignified and light body, with a body length of about 18-26 cm and a long and thick tail, which is more than two-thirds of its body length, but not as long as its body length.

The tail hair is dense and fluffy, and the limbs and fore and rear feet are longer, but the forelimbs are shorter than the hind limbs. Chinese painting squirrel ** collection (17 photos) The ear shell is well developed, and the eyes can reach when folded forward.

The Eurasian red squirrel distributed at the eastern end of Eurasia has black back fur and white belly in winter, and brown and red between gray and gray in summer; The Eurasian red squirrel at the western tip of the Eurasian continent has a brownish-red dorsal coat throughout the year.

The narrow squirrel has a slender body with a length of 17 26 cm, a tail length of 15 21 cm, and a weight of 300 400 grams. It is found in Siberia, Mongolia, Korea, Japan, northeast China, northeast Inner Mongolia, northern Hebei and Xinjiang. The coat color is gray (winter), dark brown (summer) and blue-gray (winter) and reddish-brown (summer).

No hibernation. It prefers to inhabit coniferous forests or broad-leaved mixed forests in the cold temperate or subarctic zone, and mostly forages in the forests on the slopes and banks of river valleys. Active during the day, most active in the early morning, good at climbing and jumping in trees, agile in action.

Usually there are more than 1 2 animals, but when the food is extremely poor, there is a phenomenon of group migration. Nests are built in trees or in tree cavities, and the nest is made of dry branches and debris of the tree, and is about 50 cm in diameter. It feeds on hard seeds and young leaves and buds of conifers, but also eats mushrooms, berries, etc., and sometimes insect larvae, ant eggs, etc.

Have the habit of storing food for wintering. Moult every spring and autumn. 2 3 litters per year, generally more litters in the month, 4 6 litters each time.

Squirrels are famous fur-bearing animals. Winter fur is light and warm, and it is a good product that sells well in the international market. However, due to the reduction of forest area, the number has decreased significantly.

Squirrels can be seen from flat land to forests at an altitude of 2,500 meters, and their habitats are very diverse, and they are also very adaptable to the environment after human destruction, whether in orchards, bamboo forests, secondary forests, broad-leaved forests, and coniferous forests, they can adapt very well. During the Japanese occupation period, the red-bellied squirrel was brought to the zoo in Japan for people to see, and after the red-bellied squirrel escaped from the park during the Kanto Dynasty, it has become a large group of naturalized animals in the local area in a few years, and its adaptability can be seen from this.

First, there's a big tail. Second, if you have round eyes and you can't see the whites of the eyes, you will look at them and you will be happy. Thirdly, in winter, long hairs grow on the tips of the ears, which makes them stand out.

Fourth, four toes of the forefoot and five of the hind foot. Of course, the wild squirrel is an industrious animal that is always busy running its small home. Storage, nesting, foraging.

It is a very picky elf, and in fact all the pine seeds in the world are prepared for dexterous squirrels.

It's beautiful, cute, athletic, and small.

The body is small and has a fluffy tail.
