The jump distance is more than 100 times its own length, why can fleas jump so far?

Fleas are a type of parasite. The parasite receives food and protection from another organism (the host) without giving anything in return. Adult fleas feed on the blood of mammals (including humans) and birds.

Fleas are very well adapted to this parasitic lifestyle. Their flat body makes it easy to navigate between fur or feathers. Because the skin of fleas is thick and hard, they cannot be damaged by scratching by the host.

Although fleas are insects, they do not have wings. They jump from one host to another. Their jumping ability is extraordinary, with some fleas being able to jump up to 200 times their body length.

If humans had the ability to jump, we would be able to jump about 340 meters.

This is because it has a lot of elastin on its body, which can bounce like a rubber band and has a very strong explosive power.

Because the flea's bouncing ability is very strong, and this is one of its abilities, only in this way can it survive better.

According to a CCTV science and education record program, fleas can only jump to a distance equivalent to 38 times their own length, and 200 times is a rumor.

There are still so many people who have passed on the letter for so long = = do not accept the refutation, thank you)

Fleas like to live in groups and hide in hidden corners, while urban fleas mainly hide in the gaps in the walls, the gaps in the bed boards and the gaps around the bed, usually laying one to several eggs at a time, and the total number can reach 100-200. When the temperature drops, fleas rarely move, and it is not excluded that a small number of egg-laying fleas come out to suck blood in order to replenish their physical strength. When the flea sucks blood, it will inject anesthetic into the host, and the host can not catch up with the pain, when the flea sucks enough to leave, the wound will be red and swollen, and the itching is incomparable, and the swelling will usually disappear after 15-30 days, during which it is not allowed to scratch with your hands, you need to buy swelling drugs to clean the wound, if the flea bite wound is too much, you need to seek medical attention in time to prevent inflammation.

Because the flea itself is small in density, and there is an air sac in the stomach (I don't believe that if you catch a flea and press it with your fingernails, there will be a sound of air pressure, which means that the air bag has burst), and it doesn't take much effort to jump by air buoyancy. It's like jumping high with a large hydrogen balloon hanging from a person, and you can jump high with just a light touch.

The nature of fleas, insects have their nature, such as ants are naturally strong, earthworms grow in the soil, bees collect honey, etc.

Uh: I guess it's because it's called a "jumping" flea.

According to the title, so the answer is 1 250

That should be.

Answer: The height of the flea is 3 700 of the height he can jump
