Where are the houseflies in winter?

Almost all flies die at 0 degrees. Cold and lack of moisture make them dry out. However, some of the mosquitoes survive the winter in basements or attics, where they can reduce their metabolism so far that they can survive a three-month cold spell, although otherwise they only have a life of about three weeks.


How fast is "Snail's pace"

Roman snails bring it to a top speed of about 0.0036 km / h and are thus already in the "fast troop" of the approximately 25,000 terrestrial snail species. In one hour of high speed they cover a little more than 3.5 m. There is pure power behind this apparently sluggish movement. Compared to humans, in the prone position we only have to move with the support of our abdominal muscles.


The rat, a fascinating animal!

Rats live in large groups. The rat has a keen sense of smell, and when two conspecifics meet, the smell reveals which group they belong to. The animals use their whiskers as a kind of sonar device to measure distances in the dark. If the rat emits a sound, an echo is created that the animal senses with its whiskers. The longer it takes for the sound to be reflected, the greater the distance to the opposite side. Rats run 100 m in less than 10 seconds and jump up to 2 m. Animals are true athletes. At the beginning of their lives, they are naked and blind and need the care of their mother. The mother recognizes individual cubs by their individual body odor. A female gives birth to up to 18 babies every 4 weeks. Such a rat can produce up to 1000 offspring per year. Studies show: rats are extremely intelligent. One reason science uses rats as experimental animals. Many medical successes would not have come about without laboratory rats. Rats adapt their reproduction to the respective habitat. If there is little food they produce almost no offspring, but if the food supply is abundant they can become a nuisance. Often poison baits are then laid out, but the rats are very skeptical of strangers. If one of your fellow species dies of a bait, never touch it again.


Why do mosquitoes fly to the light?

Everyone knows the phenomenon: if you are blinded by a headlight on the street at night, you often only see this one light. The surroundings almost completely disappear into the darkness. Mosquitoes and many other insects are not doing any better. For them, a source of light is the lifeline in a sea of ​​darkness. While we are still able to feel our way despite the glare, the mosquitoes can no longer leave the light, there is no one behind or in front of them for them. The reason why mosquitoes are so "blind": Their eyes are around a thousand times more sensitive than those of humans, so they are perfectly adapted to the darkness. Even a light source at a distance of one kilometer, which we can only see as a point, dazzles mosquitoes.


Are there any poisonous mammals?

It has a fur, beak, and webbed feet between its claws. It multiplies by laying eggs. Even so, it nurses its young. This peculiarity and its unique appearance make the platypus perhaps the most unusual living being. Australia is the home of the platypus. In 1798 they discovered the first specimen. They had heard of it before, but did not believe in its existence and thought it was an invention. You were wrong. And were twice surprised: because platypuses are also the only poisonous mammals. However, only the males have a hollow and mobile spur on the inside of their hind feet. The sting is connected to a poison gland in the thigh. It is a weapon for defense or against rival males. If the platypus feels threatened by a person, it tries to clasp him with his hind legs and stab him. However, such incidents are hardly known, because the animal lives mainly in water, is nocturnal and very shy. An attack is not fatal either. The symptoms: severe pain, local swelling. Fish? Seal? Duck? The platypus has something of everyone.


How does a woodpecker stand the hammering?

Competition for the hammer drill: The great spotted woodpeckers have courtship time as early as January and try to mark their territory with their love-drumming. With a top speed of 1000 km / h, the great spotted woodpecker hammers its beak into trees up to 30 times per second. This doesn't give the bird a headache, it is well equipped for the stresses of the drum roll. The skull bones are particularly solid. Above all, bone reinforcements on the forehead provide important protection. The muscles that move the head are also strong. The decisive factor, however, is that the chisel-shaped beak works according to the shock absorber principle. It is resiliently connected to the head by a movable bone. This intercepts every blow and protects the brain from vibrations. The nesting holes that the great spotted woodpecker hammer into tree trunks are up to 50 centimeters deep. It takes him a few weeks to do this.


Why does the tree frog climb the ladder?

Satellites, millions of expensive computers - as reliably as they can predict the weather, the tree frogs always manage. Or at least that's what the common mouth thinks. The living apparatus is very simple. The frog, which is in a jar together with a small ladder, climbs up when the weather is nice, and stays on the ground when the weather is bad. Real weather frogs, however, cannot be misled by this. Because in nature the tree frog is primarily attracted by the appetite for mosquitoes and insects, which buzz at higher altitudes when the weather is nice, for trees and bushes. If the weather changes, the animals prefer to hide under the leaves near the ground. The frog follows them there. If you were to feed him enough at the bottom of his glass, he would climb the ladder less and less, no matter how nice the weather was. When the tree frog climbs the ladder, happy to go up, courageous and even undaunted, holiday weather is announced (weather rule)


What color is the polar bear's skin?

They look yellowish in the zoo. slightly dirty. But you can recognize a polar bear at first glance by its white fur. Wrong, it is not even white! The polar bear's hair is actually colorless like water. Only because the light breaks through its fur. it looks white. Even more astonishing: the polar bear's skin under the fur is jet black. This way it can better absorb the sun's rays, which is essential for the animals' survival. Because they make optimal use of the sun's warmth, they still feel good at minus 35 degrees Celsius.


Why do chickens lay eggs every day?

Strictly speaking, there are only about 300 eggs a year that a hen lays. But compared to other feathered animals, this is a remarkable achievement, and actually not intended by nature. Most birds in our latitudes lay an average of four to five eggs once a year, which they then hatch. Only when their nest is destroyed do wild species replace the loss and produce offspring again. But because farmers or staff remove freshly laid eggs every day in laying batteries, the chickens suffer from this loss of nest, so to speak: They can never satisfy their hatching instinct and are therefore constantly producing new eggs. If the hens were given the chance, like other birds they would build a nest and try. to hatch the eggs. The lighting conditions in the chicken coop also play a role. When the days get shorter, the hens usually put egg production on the back burner, like other birds, they too adjust their reproductive phase according to the seasons. Factory owners use artificial light to extend the days to 14 to 15 hours and thus achieve the highest "egg potency", as the hard work of the chickens is called in technical jargon. After 14 months, however, even the busiest hen stops laying eggs. Only when the farmer gives the animals one If you take a breather, there is a second laying period.


Why do llamas spit?

Zoo visitors know the South American llama as a peacefully grazing animal. But anyone who has ever witnessed a rutting battle between two lama stallions knows that llamas are hot-blooded bundles of temperament. At first the two males just sniff each other. Then they bite and kick and spit. Not only does saliva and half-digested chyme fly through the air, but also gastric juice, which can painfully burn the rival in sensitive areas such as the eyes. Lama stallions and mares react similarly when they are frightened or annoyed by alien creatures. Many intrusive tourists in the Andes and sometimes zoo visitors have been the target of a violent spitting attack.


Interesting facts about the rabbit

The incisors of rabbits grow about 10 cm per year, but they are kept to their normal length by constant nibbling. They are only coated with hard enamel at the front, which is how they get their chisel shape when they are used. The molars only rub off when the feed is ground, so low-energy feed that requires a lot of chewing (hay, greens) is much better than grain feed. The rabbit intestine is 4.5 to 6 m long. The feed is pushed through the intestine at a rate of about 1 m per day, which is eaten today, so it only reappears after a week or less. Rabbits have to be able to constantly "mumble", they eat small amounts of feed up to 80 times a day . Long intervals between meals can be life-threatening: the animal feeds too much with ravenous appetite, but cannot vomit because the stomach muscles are weak. The result: the stomach can burst.


Which animal can live without drinking?

SURVIVAL in extreme habitats - the North American kangaroo rat can do it. It is so well adapted to deserts and dry steppes that it can do without drinking.


Animals know the healing power of herbs

When a chamois is bitten by a snake, it will eat milkweed, which it does not otherwise. This herb protects the chamois from poisoning.


Why don't mosquitoes fly in the wind?

When the wind blows, no mosquito gets into the air. At the same time, it could comfortably let itself be carried away by the draft until it encounters suitable prey. But a mosquito shouldn't be tempted by this thought, found scientists at Cornell University in America. A wind is not a steady flow of air. Rather, the air moves in a turbulent manner and forms numerous short-lived eddies. For example, if a wind was blowing at 10 miles per hour, it would throw a mosquito in a different direction every few seconds. When changing direction, the mosquito would have to endure 15 times the acceleration due to gravity, according to calculation models from flow research. But the theory is more harmless than the reality, according to the Cornell researchers. You have checked the predictions of fluid dynamics research in a series of measurements. To simplify the observations, they took small plastic particles instead of the mosquitoes, which they put into turbulent flowing water. The result: The plastic particles experienced increases in speed that were 1500 times stronger than the acceleration of gravity. The scientists were flabbergasted. That is 40 times the value predicted by the theory. The flow researchers will now have to look for errors in their calculation models. And one can only advise the mosquitoes: With all theories, just stay on the ground when there is wind!


Fatal bites from non-poisonous animals?

Even non-poisonous animals can be dangerous to humans. They do not have poison teeth, but a bite can get cadaveric poison into the bloodstream (they rarely brush their teeth). So definitely get vaccinated against tetanus after a bite. Incidentally, this also applies to a human being bitten by a human. If left untreated, it is very likely to be fatal (tetanus).


Why do cartilaginous fish have no swim bladder?

Because they do not have a swim bladder, cartilaginous fish like sharks have to swim constantly if they do not want to sink, even when sleeping and taking breaks. They keep their height by undulating their body; the caudal fin provides the main propulsion. The pectoral fins serve as elevators, similar to wings, while the dorsal fins prevent the body from tilting. In contrast to this, the bony fish with their swim bladder have a very significant improvement in the "system" of fish. Millions of years ago they developed an additional respiratory organ, a kind of simple lung, from a bulge in the esophagus. This novel respiratory organ was the key invention in the animal kingdom to conquer the land, but also the reefs. While some of these fish developed their lungs and became land animals, others returned to the sea with their invention. Here the esophagus was no longer used to breathe, but was used as a hydrostatic organ to balance the buoyancy. The cartilaginous fish, on the other hand, which remained in the sea, developed neither lungs nor swim bladders. But the shark, for example, has a large fatty liver, which reduces the specific weight and thus partially replaces the swim bladder of the cartilaginous fish.


Why are monkeys lacking the whites of their eyes?

The iris of the human eye stands out in color from the bluish-white sclera, the dermis that shines through the conjunctiva. This means, among other things, that we can relatively easily determine the direction in which a person is looking. It is different with primates: at least from a distance, it is difficult to see where they are looking. While eye contact and moving the eyeball are an essential part of communication in humans, monkeys communicate by moving their heads. Why so "cumbersome"? Japanese researchers from the Technical Institute in Tokyo examined 81 different monkeys and found that all animals had dark eyes: either the sclera was the color of the iris or the face.This is a "great camouflage effect and protection" because the monkey's gaze remains impenetrable. An aggressive predator can therefore not know whether it has already been discovered by its victim. The view of other researchers that the dark skin of the eyes serves to protect against glaring sunlight was rejected by the Japanese: nocturnal animals also have dark eyes.


How heavy can ants carry?

Depending on the species, ants can carry 30 to 60 times their body weight (3 - 10 milligrams). During investigations at the zoological institute in Cambrigde, an ant was observed hanging upside down on a glass surface with 500 mg in its jaws. Around a hundred times its own weight.
