All the most interesting things in one magazine. Interesting facts, amazing facts, unknown facts in the museum of facts

  • Reptiles, or reptiles (Reptilia) - predominantly terrestrial vertebrates, including modern, beaked, amphisbaen, and. Together with amphibians in the XVIII - 19th centuries reptiles were united into a group - cold-blooded terrestrial vertebrates.
  • Reptiles occupy an intermediate position in terms of organization between amphibians (), on the one hand, and mammals, on the other.
  • Reptiles are in many respects more similar to birds than to or mammals.
  • There are about 9,400 species of reptiles known in the world.
  • 74 species of reptiles live in Russia.
  • Reptiles flourished during the Mesozoic era, when they dominated the sea, land and air.
  • Most reptiles went extinct millions of years ago - at the end of the Cretaceous period.
  • Modern reptiles are only scattered remnants of that world.
  • Reptiles are the first true land animals.
  • Unlike larvae, in which the larvae breathe with gills and usually live in water (in some, the gills remain throughout their lives), reptiles breathe only with their lungs.
  • Due to the presence of a shell, turtles have immobile ribs, so they have developed a different method of ventilation than other reptiles. Turtles force air into their lungs by swallowing it or pumping movements of their front legs.
  • Like amphibians, reptiles are cold-blooded, i.e. their body temperature depends on environmental conditions. But reptiles have learned to partially control it by hiding from hypothermia or overheating. For example, hibernation allows you to avoid cold weather, and night activity- daytime heat.
  • All reptiles have tough, dry skin covered with scales. Its main function is to protect the body from drying out.
  • Such tough skin interferes with growth. Therefore, almost all reptiles are characterized by molting. Snakes and lizards shed their skin quite often. This is not typical for crocodiles. Their skin can grow along with their body.
  • The largest living lizard is.
  • Reptiles lay large eggs covered with a dense shell.
  • The muscular system of reptiles is better developed than that of amphibians.
  • Many reptiles live in very dry places, so maintaining water in their bodies is extremely important to them. They lose almost as much moisture through their skin as birds and mammals. In mammals, a high respiratory rate leads to high evaporation from the surface of the lungs, while in reptiles the respiratory rate is much lower, and accordingly, water loss through the lung tissue is minimal.
  • There are reptiles that need absolutely clean water. These are caimans - representatives of the Crocodile order. For this reason, their distribution area is quite small.
  • Of all reptiles, they spend the most time in the water, coming onto land only to lay eggs or bask.
  • Reptiles are found throughout the world, but are especially numerous in warm areas and are practically absent in cold areas outside the distribution of woody vegetation.
  • The most highly organized of reptiles are crocodiles.
  • Crocodiles are among the largest modern reptiles.
  • Typically, reptiles have widely spaced limbs. Crocodiles are the only reptile to move their legs under their body when moving quickly, and when running they go into a gallop; some species are capable of reaching speeds of up to 17 km/h.
  • The crocodile opens its mouth to cool, and the water evaporates from it; At the same time, the small ones peck stuck pieces of meat and leeches from the crocodile’s mouth.
  • Diurnal lizards have color vision. This is very rare in the animal world.
  • Many species of lizards, escaping from an enemy, are capable of throwing off part of their tail (autotomy).
  • In the dark, the eyes of large individuals glow red, while those of small individuals glow green.
  • The only place on Earth where alligators and crocodiles coexist is Florida.
  • Mississippi alligators are capable of changing the surrounding landscape. Sometimes they live in a swamp. To have plenty of standing water, alligators in swamps dig ponds by loosening and scattering the soil with their hind legs and blows of their tails. They constantly clean the ponds in which they live from thick mud and excess vegetation, pushing it out and carrying it to the shore. Willows grow along the banks of ponds dug by alligators. Tree roots bind the soil, forming islands of land among the swamps.

Biologists of the 17th-19th centuries. classified amphibians and reptiles into one group, which they called “reptiles”.

Approximately 9,400 species of reptiles walk and crawl on the Earth. Only 77 of them live on Russian territory.

About similarities

  • Many reptiles combine several animal traits: the simplest amphibians and more developed vertebrates.
  • were the largest creatures that ever lived on planet Earth. Despite the fact that they belonged to reptiles, birds became descendants of lizards.

  • No animal is as similar to birds as reptiles.
  • Dinosaurs appeared on earth later than turtles.

About the senses, vision and coloring

  • Most cold-blooded animals have a third eye, hidden under a thin layer of skin. With its help, the brightness of sunlight, the power lines of the earth's magnetic field and spatial orientation occurs. This may not be a complete list of the abilities of the “extra” eye, but this has not yet been established.

  • Instead of eyelids, many lizards and snakes have a transparent membrane.
  • It is known that chameleons are capable of changing color and becoming covered with spots or stripes. Until recently, this feature was considered a way of protection from, but recently scientists have found out that animals, first of all, communicate this way.

  • The world of reptiles that are awake during the day is yellow-orange.
  • Snakes do not have eardrums, so they practically cannot hear. Instead of sounds, they focus on earth or water vibrations.

  • Turtles perfectly feel the lightest touches on their shells.
  • About 40 thousand years ago, Australia was inhabited by crocodiles that never entered water bodies. They were land-based.

Body, size, perception of sounds

  • The most massive snake on the planet is the anaconda. It can be up to 7 m long and weigh from 30 to 70 kg. A snake with a maximum length is considered to be 7.5 meters reticulated python.

  • The sounds made by most reptiles resemble whistling or hissing.
  • The chameleon's tongue sometimes grows up to 0.5 m in length.

  • Crocodiles tear their prey into pieces, swallowing them without chewing, since they do not know how to do this. They even have a special tooth in their mouth that helps dismember prey.
  • Alligator teeth grow throughout their lives. Instead of broken and fallen ones, over 3000 pieces grow.

About family

  • Reptiles are cold-blooded creatures, but there are Tegu lizards that, during the search for partners, experience chemical reaction, which increases body temperature for greater attractiveness.

  • The sex of the embryos depends on the place in which the eggs were laid, or rather, its temperature.
  • Reptiles, for the most part, are not caring parents. Having laid their eggs, they do not care about them, counting on the fact that newborn babies will show miracles of independence. Only turtles became an exception to this rule.

Reptile facts

Snakes, alligators, and lizards have something in common. They all reptiles. And yes, for some people they might send shivers down the spine at the mere mention. Reptiles are one of the oldest animal species on earth. Read on to find out some facts about them.

For example, lizards are more closely related to birds than to turtles. Crocodiles belong to the order Crocodiles and Alligators. The order Rhynchocephalia consists of only two species, known as tuataras, which are native to New Zealand. The Scaly order consists of lizards, snakes and other similar creatures. All turtle species are included in the order Testudines.

Surprisingly, the distance between the alligator's eyes in centimeters is directly proportional to the alligator's length in meters.

What animals do the third eye help navigate in space?

The third eye, or parietal eye, is a common light-sensitive organ in some agnathans, fish, amphibians, and reptiles. It is located between the main eyes and is much smaller in size, and is also covered with skin, although more transparent. It contains a retina, a nerve and an analogue of a lens, which allows it to perceive the direction of sunlight, the polarization of light from the sky and, according to some hypotheses, the lines of force of the Earth's magnetic field. For many species, the necessity of the parietal eye for normal orientation in space has been experimentally confirmed. In birds and mammals, all that remains of the third eye is the pineal organ - the so-called pineal body, which is part of the endocrine system.

Which person have you been friends with for 20 years? wild crocodile?

In 1991, Costa Rican Gilberto Sedden discovered a dying crocodile on the river bank, shot in the left eye. He took him away in a boat and nursed him for six months at his home, where he not only fed and gave him medicine, but also cuddled the reptile, which he named Pocho. When Pocho recovered, Gilberto took him to the river, but he returned to the house after him and began to live in a pond nearby. They began to swim together every day, play and hug, and later Gilberto began to organize performances for tourists from this. In 2011, Pocho died of old age.

What marine and terrestrial reptiles are able to mate and produce offspring?

The Galapagos Islands are home to both marine iguanas, which eat mainly algae, and terrestrial iguanas, called conolophans, which eat mainly cacti and prickly pears. Despite the fact that these lizards belong not only to different species, but even genera, they are able to mate and produce viable offspring. Hybrid iguanas feel equally good under water and on land, and due to sharper claws they can climb up cacti, unlike conolophids, which only pick up fallen fruits. However, hybrids are no longer able to reproduce.

How high can crocodiles climb trees?

Crocodiles can climb trees and do it willingly. Watching individuals different types in Australia, Africa and America, zoologists have noticed crocodiles climbing trees to a height of up to two meters, although according to the testimony of some local residents they can climb much higher - up to ten meters. While young crocodiles can climb vertically up a trunk, adult crocodiles can only climb branches inclined toward the ground or water. Scientists associate this behavior with the desire of crocodiles to explore their territory and bask in the sun.

In which animals is necrophilia a common reproductive strategy?

In Amazonian frogs Rhinella proboscidea, the number of males is 10 times higher than the number of females. During the mating season, males, fighting for females, form large balls, under which the females sometimes drown. This fact does not stop some males - instead of fighting for the living, they extract eggs from the bodies of already dead females and fertilize them. Biologists have called this unique behavior “functional necrophilia.”

What animals eat their tail and in what cases?

The tail, which the lizard throws away in case of danger, “dances” to attract attention to itself. for a long time, and in some species it even makes sounds due to the friction of scales against each other. The North American scincella, after throwing off its tail, returns to this place after some time, and if the predator does not feast on the tail, it eats it itself, since it contains a large number of nutrients. In rare cases, the tail breaks, but does not break off completely - then the lizard may grow another tail at the site where the vertebrae are broken.

Why are lizards that reproduce by parthenogenesis still involved in mating games?

Many species of lizards are capable of reproducing through parthenogenesis, that is, without the participation of a male. Parthenogenesis is the most well studied in the population of lizards Cnemidophorus neomexicanus. Despite the complete absence of males among them, reptiles are still involved in mating rituals. Immediately after laying eggs, the female retains increased level progesterone, which encourages her to play the role of a male, climbing on other females whose laying is yet to come. Studies have shown that the productivity of lizards after such “mating” due to the release of hormones is higher than that of isolated individuals.

How does a snake charmer make a snake that is deaf to the sound of a pipe dance?

The spectacled snake from the genus of cobras is absolutely deaf to the sounds of the pipe. From the outside it may seem that the snake seems to be dancing, moving to the beat of the snake charmer’s melody. In fact, it simply follows the movements of the pipe, and also reacts to the vibration that the caster creates by tapping his foot. By the way, the lives of Indian masters of this profession are not in danger during the performance - all the venom from the cobra’s teeth is removed in advance.

What animals collect moisture in front of their eyes and then drink from it?

Gecko lizards do not have eyelids, so they are forced to periodically wet a special transparent membrane over their eyes with their tongue. And the web-footed geckos, which live in the deserts of Namibia, use this feature for the reverse process. Almost every morning, fog falls on the dunes here, after which liquid condenses in front of the lizard’s eyes. The gecko then licks it off to quench its thirst.

Which snake feeds exclusively on bird eggs, much larger than itself?

The African egg snake is unique in that it can feed exclusively on bird eggs, the diameter of which can significantly exceed the size of the snake itself. She succeeds in this thanks to the very mobile joints of the skull bones, underdeveloped teeth and special processes of the cervical vertebrae. It is thanks to them that the snake opens the shell, swallowing the liquid and then spitting out the remains of the shell.

Which chameleon muscle hardly slows down as the temperature drops?

Chameleons are cold-blooded animals, and as the air temperature drops, their nervous and muscular activity slows down. However, the speed of throwing out the tongue, which chameleons use to catch prey, decreases very slightly: if at 35 °C it is 4 m/s, then at 15 °C it is 3.4 m/s. This feature has helped chameleons gain an advantage over other reptiles that become inactive in cold weather.

Where do soft-shell turtles live?

Not all turtles have a hard shell. Turtles of the soft-bodied superfamily completely lack horny scutes, so their shell is soft and leathery to the touch. Most species of this taxon also have a greatly reduced bony carapace. This is explained by the fact that such turtles spend most of their time motionless, burrowing into the sand at the bottom of the reservoir and waiting for prey.

What type of lizard is both oviparous and viviparous?

An Australian lizard called the yellow-bellied three-toed skink is known in different ways childbearing within the same species. In populations living on the seashore, the cubs hatch from eggs, and in cold mountainous areas these lizards are viviparous. The genus of forest lizards found in our latitudes also have similar properties - they lay eggs only in the southwest of their range.

What animal can get drunk by simply burying itself in wet sand?

The Moloch lizard, living in the deserts of Australia, has unique ability collect water with your skin. The liquid that gets on the skin is not immediately absorbed, but enters the lizard’s mouth through microscopic channels between the scales. Moloch is able to extract water even from wet sand, simply by burying his belly in it.

Where can you see flying snakes?

In Asian countries you can find flying snakes. They can climb to the tops of trees and from there soar down, spreading their ribs to the sides and turning into a kind of flat ribbon. Some individuals can cover distances of up to 100 meters in this way.

No animal can change colors this way and look in two directions at once, so the chameleon is definitely worth learning more about. The naked eye can see that the chameleon is one of the most beautiful and unusual reptiles on the planet. Here are ten interesting facts that you might not know.
1. Almost half of the world's chameleon species live on the island of Madagascar, with 59 different species that do not exist anywhere outside the island. There are approximately 160 species of chameleon. They are distributed from Africa to southern Europe, from southern Asia to Sri Lanka. They have also been introduced into the United States in places such as Hawaii, California and Florida.



2. Read more about color change. Most chameleons change color from brown to green and back, but some can take on almost any color. In just 20 seconds, repainting can occur. Chameleons are born with special cells that have color or pigment in them. These cells are found in the layers beneath the chameleon's outer shell. They are called chromatophores. The top layers of chromatophores have a red or yellow pigment. The lower layers have blue or white pigment. When these pigment cells change, changes in the chameleon's skin color occur.


Chromatophores change because they receive a message from the brain. The message tells the cells to expand or shrink. These actions cause the cell's pigments to mix, just like paint. Melanin also helps chameleons change color. Melanin fibers can spread like spider webs through layers of cells, and their presence causes the skin to darken.


Many people think that the color of chameleons blends in with their environment. Scientists do not agree with this. Their research shows that light, temperature and mood cause chameleons to change. Sometimes a change in color can make a chameleon appear calmer. Sometimes this helps the reptile communicate with other chameleons.


3. A chameleon's eyes have a 360-degree view and can see in two directions at once. Chameleons have the most special eyes of any reptile. They can rotate and focus separately to observe two different objects at the same time, allowing their eyes to move independently of each other.


This gives them a full 360 degree arc of vision around their body. When prey is located, both eyes can be focused in the same direction, providing acute stereoscopic vision and depth perception. Chameleons have very good vision for reptiles, allows them to see small insects at a long distance (5-10 m).


4. Chameleons vary greatly in size and body structure from maximum length, varying from 15 millimeters in males of Brookesia micra (one of the smallest reptiles in the world) to 68.5 centimeters in males of Furcifer oustaleti.


5. A chameleon's tongue can be 1.5-2 times the length of their body. They can shoot their tongue out of their mouth to capture prey. It was recently discovered that smaller chameleons have proportionally more large tongues than the big ones. The tongue is thrown with extremely high efficiency, reaching prey in just 0.07 seconds.





7. Males are usually much brighter. Many have decorations on the head or face, others may have large combs on top.



8. Chameleons don't hear very well. Like snakes, chameleons do not have an outer or middle ear, and thus do not have an eardrum. However, chameleons are not deaf. They can pick up sound frequencies in the range of 200-600 Hz.



9. Chameleons see in both normal and ultraviolet light. Chameleons exposed to ultraviolet light show greater activity and are more likely to hunt.



10. The American chameleon is not actually a chameleon. Anolis carolinensis is not a true chameleon, but a small lizard of the iguana family.
