The class of vertebrates, which occupy an intermediate position between amphibians and mammals, is called reptiles (reptiles). More similarities are observed with birds. This class includes the following animals on the list:

• crocodiles;
• turtles;
• snakes;
• lizards;
• dinosaurs (fossil shape of animals Mesozoic era).

The overall characteristic of Presbysey

Like amphibious animals, reptiles refer to cold-blooded beings. In other words, their body temperature is determined by the surrounding space. To some degree of reptiles, they are able to adjust their temperature, covered from supercooling. For example, in the winter time of the year, the animals fall into the hibernation, and during the periods of strong heat begin to hunt at night.

Reptiles have rigid skin covered with scales. The main task of which is to protect the body from drying out. For example, the turtles are top protection is provided by a solid shellThe crocodiles on the head and back there are solid plates of bone origin.

The breath of the reptiles is carried out only through the lungs. Some animal species have the same size and equal degree of development, and others, such as snakes and lizards, the right light has a larger size and is located across the body cavity. Turtles have fixed ribs due to the shell, so the body ventilation is organized in another way. In the light air enters when the front legs are swinging or intensive swallowing.

The bone skeleton reptile is well developed. The amount and form of the ribs depends on the specific type, but they are available at all class representatives. Almost all the turtles have fucked bone plates of the shell and spine. In the serpent edge designed for active crawling. Rib lizards are used to support the metering of a fan-shaped form for planning in the air.

Most reptiles have a short language that cannot be aligned. Snakes and lizards have a long tongue, divided by the sun, which is able to extend far from the mouth. For this type of animal, these are the most important organs of feelings.

To protect OT. ambient In small reptiles, the original color is observed. Turtles are reliably protected by a dense shell. Some snakes are poisonous.

According to reproduction bodies, reptile has similarities with birds. As a rule, reptiles belong to the egg-owned animals. But in some species until the hatching eggs remain inside on the oil area. This type includes some types of lizards and viper.

Reptile classification and their distribution

Modern reptiles divided into four detachments:

• turtles (about 300 species);
• crocodiles (25 species);
• scaly (about 5,500 species of lizards and snakes);
• gatteria (Tiatara).

The last detachment refers to the only representative of the climber animals among reptiles.

Presbysey distributed worldwide. The greatest number is seen in warm areas. In the regions with a cold climate and the lack of wood vegetation, reptiles are practically not found. Representatives of this class dwell on Earth, in water (fresh and salty) and in the air.

Ancient fossil reptiles

Reptiles are known since the time of the coal period. They achieved the largest size in Perm and Triassic periods. At the same time, an increased multiplay of animals was observed, which settled all new territories. IN mesozoic era The pregnancy of reptiles was overwhelming, and on land, and in water. This period is not in vain received the name of the century reptiles.

Turtles

To one of the most famous types of reptiles include turtles. There are both sea and land representatives of animals. The species is distributed in the entire world. Animals are also possible contain at home. The most ancient representatives of the turtles were discovered 200 million years ago. Scientists believe that they occurred from the primitive species of quotosavrov. Turtles have practically harmless animals, they are not dangerous for people.

Animals of this species has a bone shell. Outside it is formed by numerous separate elements made of horny fabric, which is connected by plates. For breathing ground turtles, light function excellent. Water representatives Classs breathe with the help of the mucous membrane of the pharynx. main feature These animals are longevity. Average age Turtles exceed the life expectancy of any other reptiles.

Crocodiles

Animals belong to one of the most dangerous species Reptiles. The origin of crocodiles is associated with ancient reptiles, the size of which exceeded 15 meters long. Scientists were able to find the remains of ancient crocodiles at all continents globe. Modern representatives of this class have more familiar dimensions. But among the reptiles still remain the largest species.

Almost all the time crocodiles are in the water. On the surface only ears, nose and animal eyes appear. Crocodiles are floating with the help of refilled tails and paws. But at great depths there can be only single class representatives - a rowing look. Crocodile nests are located on land. In some cases, they also crawl out of the water to warm up.

Reptiles have a strong powerful tail, and also characterized by high movement speed on land. Therefore, crocodiles are extremely dangerous for a person. A sharp unexpected throw can catch people by surprise. Most dangerous representatives Crocodiles are alligators.

Chameleons

This type of lizards is known to almost everyone. Reptiles are known for their unique color, which performs a masking function. Animal skin can change its color depending on the environmental conditions. Chameleons live on trees. Some people contain these cute creatures and at home.

Reptiles are pretty whimsal care. They need a spacious terrarium, which is equipped with special lamps. It will take a tree, a small pond, floor heating and excellent ventilation. Fell chameleons insects. Therefore, their presence will also have to take care of the owners.

Iguana

Currently, more and more lovers of pets - Iguan appears. This representative of lizards also requires special care. Iguanas should be contained in a special terrarium, which can maintain a specific temperature mode. From food, homemade iguana prefer fresh fruits and vegetables, as well as greens. With good care and creating optimal conditions of existence, lizards at home can grow large enough. Maximum weight iguan - 5 kg. It is difficult to contain such a pet home, it will require a large financial infusion, as well as significant labor costs.

Iguana belong to those rare species Reptiles, who have a molting. Most reptiles experience this period in two days, and Iguan is stretched for several weeks.

Varana

There are about 70 species of representatives of Varanov. They live in various territories. Animal dimensions are very impressive. In short varana, the length is about 20 cm, and other representatives have much more (about 1 meter). Major Varana are the most expensive views. Their sizes reach three meters in length, and the mass is 1500 kg. No vain of such animals is called modern dinosaurs.

Warana covered with large scales. They have strong paws with a chain grip and powerful long tail. The language of the animal is also different large sizesAt the end it is divided in half. Lizards can only smell in the language. In the color of animals, gray and brown shades are dominated. Young representatives of the class are often encountered with a spotted or striped scales. Warana live in regions with a warm climate. Most often found in Australia, Africa and South Asia. Depending on the habitat, the Varana is divided into two types. The first of them lives on a deserted terrain with dry trees and shrubs. And the second is closer to the rainforest and reservoirs. Some representatives of Varanov live on the branches of trees.

Gecko

Unique reptile representatives that are capable of sticking to any surfaces, even the smoother. Gecko can climb on smooth glass walls, hanging on the ceiling and many other interesting things. The lizard is able to hold on the surface with just one paw.

Snakes

These are famous representatives of reptiles. The main difference from other species is the body shape. Snakes have a long torso, but do not have paired limbs, eyelids and outdoor auditory passages. Some of these characteristics are present in certain types of lizards, but all together such signs are observed only in snakes.

Snake the body consists of three elements:

• head;
• body;
• tail.

Some representatives retained rudimentary forms of limbs. A large number of Snake species poisonous. They have furred or tubular teeth, which contain poison. This dangerous liquid comes from salivary glands Animal. All internal serpene organs differ from standard indicators. They have an oblong shape. The bladder in animals is absent. There is an eye on the eyes horny shellwhich was formed from the thorough eyelids. Snakes that lead a daily lifestyle, have a transverse pupil, and night snakes are characterized by a vertical position of the pupil. Because Anvisory passage in animals is absent, then only loud sounds are heard for them.

Sizz

These are representatives of one of the varieties of snakes. Their main feature is not poisonous. Frecks have bright scales with a large ribbed surface. Animals are common near reservoirs. As nutrition, amphibians and fish are used for them. Sometimes the hood manages to catch a bird or a small mammal. Such snakes do not kill their prey, they swallow it entirely.

If the snake learned the danger, then she pretends dead. And when attacking it, a liquid with an extremely unpleasant smell is distinguished from the mouth. Frecks multiply on vegetable soils covered with wet moss or natural garbage.

The list of modern reptiles can be continued for a very long time. All class representatives have certain similarities characteristic of this type of animals, as well as clear differences. Such animals are of great interest for scientists and lovers from around the world. Their unique features can tell about many.

Reptiles, also known as reptiles, are the class of animals, as a rule, terrestrial and vertebrates. It includes such creatures as turtles, crocodiles, lizards, snakes. For several centuries ago, they were combined with amphibians, and now they consider close to birds. Many reptiles are so unique that the study of this class will be interesting even not a professional biologist. What are the reptiles of animals? Photos and names, as well as some information about each, posted in our article, will help you figure it out.

Turtles

Perhaps with a shell - the most famous include both land and sea speciesThey meet in many countries of the world, in addition, they often contain even those who are not a big fan of exotic. The turtles appeared two hundred million years ago, it is believed that they originated from primitive quotosavrov. For a long time, they liked people - it is practically no dangerous animals that cause associations only with wisdom and tranquility. Turtles are the only class having a shell. Inside it is bone, and outside is formed by a horn cloth from a plurality of individual elements connected by plates. Land turtles Breathing light, and aqueous - with the help of the mucous membrane of the pharynx. In addition, these animals are unique in that they live longer than any other reptiles. The names of the oldest turtles include such species such as Caroline boxed, one of the caught reptiles was 130 years. However, B. wildlife More impressive numbers are possible, simply these individuals did not fall into the hands of researchers.

Chameleons

Perhaps, many people, if they offer to recall the names of reptiles, not least will say about these lizards. Unusual reptiles live on the branches of trees and are known for their unique disguise. Their skin can change the color according to the surrounding environment. It is not surprising that chameleons often keep at home. But it is worth considering that these are quite demanding reptiles. Photos and names are not all that needs to be studied before buying an exotic pet. First you need to deal with the conditions of content - the chameleon need a spacious terrarium and special lamps, small reservoirs and wood, with excellent ventilation, and insects will have to buy.

Iguana

Listing the names of reptiles, which often become homeless, can not be mentioned iguan. He became very popular in last years, and the number of such pets can be measured with tens of thousands. But you should not believe the information that keeping such a lizard as simple as a cat or a dog. Iguana is a picky creation, the existence of which requires a lot of attention and cash. For lizards need a special terrarium with a special temperature regime, as well as food from fresh vegetables, fruits and greens. If you observe all the conditions, Iguana can grow up to five kilograms! A unique feature of these creatures is a molt - many reptiles happens quickly, and sometimes it takes weeks.

Crocodiles

These animals are perhaps the most dangerous and frightening reptiles. Names can be different - crocodiles, gavuals, alligators, currens, but in any case it is creatures from one detachment. They originated from reptiles for more than fifteen meters long and are known for a long time. Paleontologists discovered traces in Europe, North America, India and Africa. Now their dimensions are much more modest, but they still remain the largest reptiles. The crocodiles are carried out most of the life in water, exposing only eyes, nose and ears from it. The tail and paws with a membrane make a swim in an easy task, but only a ridge variety can swim far into the sea. On land, they build nests, and sometimes they just choose to warm up. The names of the reptile animals of this squad differ, but also alligator, and the crocodile combines one - they are dangerous for a person. Reptiles have an incredible speed and a strong tail, so a sudden throw can cost a careless traveler of the limbs or even life.

Snakes

This is another reptile, whose names are known to everyone. They differ from other reptiles long body shape, lack of paired limbs, eyelids and outdoor auditory passes. Separate such signs can be found in lizards, but all together - only in snakes. Now a person knows their three thousand species. The body of the snake consists of three parts - head, torso and tail. Some species in rudimentary form preserved the hind limbs. Many of them are poisonous, with tubular canal or furillary teeth, which contain a dangerous liquid, incoming there from all internal organs differ from the elongated form, and there is no bladder. Eyes covers a transparent horn shell formed from the thorough eyelids. In the serpent, the leading day lifestyle, the pupil is located crosswise, and at night - vertically. Due to the reduced ear, only loud sounds differ.

Sizz

Can be very different, despite the fact that they relate to the same detachment. For example, cakes are snakes, although some believe that this is a separate type. In fact, these reptiles are simply not poisonous. However, these are snakes. They are distinguished by expressive scales with large ribs. Most of the already live in reservoirs and feed on fish or amphibians. Less often, they manage to catch a small mammal or bird. I swallowing prey live, without killing her. With the danger of reptiles, they are pretending to be dead, and during the attack, liquid is distinguished with an unpleasant odor. For reproduction, curses are looking for a bunch of vegetable garbage, manure or wet moss.

Varana

These are very famous reptiles, whose names are most often associated with a domicile variety. In fact, there are seventy species, and they live not only on certain islands. However, they all differ in impressive dimensions - only short-tighted reaching up to twenty centimeters, and all others can grow to meters. But, of course, the Komotors are the largest, with a weight of one and a half centners and three meters long. That is why they were called dragon. Varanans have tenacious and severe paws, a muscular long tail and a large scales. Long tongue with a split at the end of the lizard feel smells. The color is most often inexpressive, in gray, sandy and brown tones, although young individuals can be striped or spotted. Warana live in warm countries in South or Africa and in Australia. In place of habitat, they can be divided into two groups. The first prefers the desert terrain and dry shrubs, and the second keeps closer to the water in tropical forest. Some varana love to spend time on trees.

Gecko

These are reptiles, the names of the species of which are associated with a unique ability to glue even to the smoother surfaces. Little heckon can climb on a vertical glass wall or even hanging on the ceiling. In order to keep your weight, a lizard can hold on to one paw. Such a feature surprises people for several millennia - the skill of Gecko was trying to solve another Aristotle.

Modern science knows the answer - on the fingers of the reptile there are small ridges with thin bristles, which help her to hold on the surface due to the law of interaction between molecules.

On Earth makes our planet so unique and beautiful. Surprisingly, it still happens to open new animal species, which were not previously known to science. The most interesting for scientists are reptiles. This is the type of animals that are considered the most ancient on the planet and have not yet been fully studied by scientists. It is about them that we will tell you today.

Reptiles - who are these?

Each schoolboy can tell a lot of interesting things about these amazing representatives of the animal world. Another course of biology is known that reptiles are a special class of animals that are currently represented by four squads. They relate to cold-blooded vertebrates and therefore prefer to dwell in countries with a warm or hot climate. Many people believe that reptiles and amphibians belong to one class, but in fact it is not. Reptiles can live both in the water and on land, and their skin covers, in contrast to the skin of amphibians, are covered with small scales, allowing preserving precious moisture in the body.

The class of reptiles, or reptiles, as they are called, millions of years ago dominated our planet. Helped them in this egg shell, which reliably defended the future young from all dangers. Ikrinka same amphibians could easily damage. In addition, the cubs reptiles appear on the light fully adapted to independent life, which cannot be said about amphibians passing several stages of development to complete mature.

Reptiles: what looks like

Reptiles are animals that have an oblong body and small short legs (some species are missing). The skin is always dry, and the need for water and fresh air is minimal. When moving on the ground, animals are asleep on the surface, so they are called "reptiles". Reptiles grow very slowly, and their growth occurs throughout life. The life expectancy of certain types of reptiles reaches six hundred years.

Most reptiles are perfectly transferred hot weather And literally "charged" from the sun. They are enough to crawl on warm surface After the cold night, so that the body temperature increases to about human. In too hot days, reptiles are hiding in the shade.

Types of Reptile

Reptile class is represented by approximately family of thousands of species and four squads:

1. Turtles

It is believed that the turtles appeared on the planet more than two hundred million years ago, it remained to this day about six and a half thousand different species. Moreover, the turtles are in nature twelve families. Scientists argue that such a variety of preserved species of this detachment was ensured by their durable shell provided animals to protect against predators.

2. Lizards and snakes

They are combined into one detachment, but have some differences. As scientists were convinced, lizards live in almost all corners of the planet, there are more than three hundred fifty species. And they are so diverse that it is difficult to reveal some common features between all lizards.

Snakes cause scholars of delights, there are three thousand species on the planet.

3. Crocodiles

These creatures are the closest relatives of birds and are considered the most ancient animals on Earth. Only three kinds of crocodiles have been preserved to this day.

4. Gatteria

This animal is the only one in its kind and lives only in one place of the planet.

When did the reptile appear on the planet?

The class of reptiles (or reptiles) appeared on our planet 340,000,000 years ago. Almost immediately they spread across the planet, some species chose the land, while others went down to sea depths. Flying reptiles appeared later than other species, but also took their niche in the animal world of the Earth.

Scientists believe that the ability of reptiles to grow all his life and thwarted them in the end. Indeed, in the process of evolution, they have achieved huge sizes, and this is, as you know, leads to the disappearance of the species.

The perception of the world reptile

Reptiles are unique animals that have not only vision and hearing, but also special organs of feelings that allow them to perfectly adapt to various conditions. For example, snakes can perceive and classify odors using special cells in the language. Many of the reptiles have the ability to distinguish between infrared radiation, coming from warm-blooded creation. This allows some reptiles to hunt even at night.

Lizards, for example, are very much relied on their eyesight. They see the world in the color spectrum and, according to scientists, can also distinguish heat, coming from items. In addition, most reptiles do not have a century, so they can not blink. They moisturize the mucous membrane of the eye through the language.

Reproduction Reptile

Most reptiles postponing eggs. It ensures the safety of their offspring and allows it to develop to the level of an adult individual, while in the shell. This feature gives a large percentage of the survival of the cub in nature, which, in turn, ensures the safety of the species.

Some types of reptiles are nobbing, it belongs to snakes and lizards. Their offspring is also born prepared and can exist separately from parents. Surprisingly, the young reptiles from the moment of birth can hunt and completely repeat the habits of their parents. Moreover, this quality is congenital, parents do not teach their offspring.

How is the growth of reptile?

As we said, reptiles grow all their lives, but for this they need to lift. The fact is that the skin reptile is quite dense and tough, in composition it is very reminded by human nails. In the cushion of reptiles, quite a lot of keratin, so over time the skin becomes quite solid and holds back the growth of the animal.

That is why the reptiles pass the rinch process. Under old leather, a thin layer of new and delicate peel is started to grow, which is gradually compacted. As a result, the animal throws out the old skin, getting out of it from the stocking. This is especially noticeable on the snakes, they as if they crawl out of their skin by turning her inside out. Lizards, for example, linen a little different way - they dump the skin with large pieces for several days.

The reptiles remaining in our world from the most ancient times are the object of close attention of scientists of the whole world. Their abilities are used in many areas of science, as well as robotics. These amazing nature creatures can give us a lot of discoveries, because there was no wonder only they managed to live our days from the non-distant dinosaur era.

Class Required: Face Features

Reptiles have those interesting features, as internal fertilization, as well as yays tabwhich are rich in nutrients and covered with a sufficiently dense protective shell, which gives them the opportunity to develop on land.

In all animals belonging to the class of reptiles, the body is covered by protective formations in the form of scales forming solid cover. They always have a dry, evaporation of moisture through it is impossible, thanks to which they can live in dry places.

The respiration of reptiles is carried out extremely lightweight, having a more complex structure in comparison with light lungs. Such breathing became possible due to the fact that reptiles had a new skeleton department - a chest, formed by a number of ribs, which are connected from the dorsal side with the spine, and from the abdominal side with the sternum. Thanks to the special muscles, the ribs are mobile, which contributes to the expansion of the chest, as well as the lungs in time inhaling and falling into them when exhaling.

The changes in the structure of the respiratory system affected the changes in blood circulation in all animals included in the class of reptiles. Most of them have a heart 3-chamber and as much as amphibians 2 circle circle. And the structure of the heart in reptile is characterized by a more complex structure, compared to amphibians. His ventricle has a partition, at the time of a reduction in the heart, almost completely dividing it on the right (or venous) and left (or arterial) of half.

It is such a structure of the heart and other than that of amphibians, the location of the main vessels contributes to a stronger demaring of venous and arterial flows, due to which the body of reptiles is better supplied with more oxygen blood.

The main vessels included in the large and small circles circulation are typical for all ground vertebrates. But the main difference between the small circle of blood circulation of amphibians and reptiles, is that the latter has disappeared the skin veins and artery, and the small circle of blood circulation includes exclusively pulmonary vessels.

Science is known about 8,000 existing species Reptiles who live on all continents for the exception of Antarctica. The class of reptiles includes the following detachments: final, scaly, crocodiles and turtles.

gecko

Reproduction of reptiles

In the ground reptiles internal fertilization. In the process of mating, the male introduces the spermatozooid female in the clock, then they penetrate the egg cells, where they occur their fertilization. Eggs develop in the body of the female, and then she puts them out on land, instilled in pits.

The egg is covered with a special dense shell. It contains the necessary supply of nutrients, due to which the development of the embryo occurs. After time, there are no larvae from eggs, like amphibians, but an individual who are capable of independent life.

Turtle postponed eggs

This squad includes real "live fossil" called gatteria(Lat. Sphenodon Punctatus.), which is the only species preserved near the coast of New Zealand, on small islands. This animal, similar to a lizard, is very small and maintains a main lifestyle. The structure of Gatteria has features that reptile reptiles with amphibians: the bodies of her vertebrae are bicked, and the chord is preserved between them.

Gatteriya.

Detachment Scaly

Scaly (lat. Squamata.) Also are one of the commercial-type crop-type detachments. This group includes suburbs: lizards, chameleons, snakes and amphisben (diversion). The squad received such a name, because The bodies of all its representatives are covered with special horny scales or shields.

A typical representative of the cups is lizard is angry. Her external structure It indicates that it is ground animal. There is no swimming pooling on its five-way limbs, and the fingers are armed with short curls, so that its body crawls on the surface of the earth, contacting it, i.e. Presbytent (hence the name).

Xamelion.

Squad crocodiles

Water vertebral crocodiles (lat. Crocodilia.) - are the largest and most highly organized predatory reaches, adapted to the water lifestyle. These representatives of the class reptiles live in the tropics. All crocodiles are semi-wheeled predators that are fed by water, incoming and carbon animals.

Detachment Turtle

The turtle detachment includes about 328 modern species belonging to 14 families and two suburbs. They are widespread both tropical and moderately climatic zones, both in water and on land.

Turtles (lat. Testudines.) They differ from the other durable, well-developed carcire formed from bone plates, which are covered with a corneum. It consists of two parts: upper convex shield and lower flat shield. Sheets of turtle serves the main protection against enemies.

Reptiles are an unusual class, which is located between amphibians and mammals. Otherwise, they are called reptiles. But not everyone knows who reptiles are.

Reptiles are vertebrates that have similarities with birds and mammals.

Let's study this class in more detail.

Who are such reptiles

Representatives of this class are cold-blooded creatures. The temperature of their body is determined by the ambient temperature. But they have one feature, they can regulate their temperature themselves. The ancestors of reptiles are amphibians. Winter reptiles, as a rule, sleep. And in hottime, only a nightlife is leading.

Reptile leather rigid and covered with scales. Such skin is needed in order to protect the body from drying out. Breathe these animals are only through the lungs. In some representatives of this class, lungs have the same dimensions, and others have one easier more than the other. And this is the norm. The skeleton in reptiles is well developed. There are all the ribs, but their number depends on the representative of this class.

Almost all types of this class have language, But someone is short, and someone is very long. And he is the main organ of feelings. To protect yourself from enemies, these animals change painting, someone has a solid shell, and some are generally poisonous. These animals breed like birds, that is, lay eggs.

The following animals belong to the class of reptiles:

• Snakes;
• Lizards;
• Turtles;
• Dinosaurs.

Types of Reptile

Reptiles or reptiles are divided into four detachments:

Reptiles can be found anywhere, but their largest amounts live in warm countries. Where there is always cold and little vegetation, these animals are very rare. Reptiles live everywhere. And in water, and on earth, and in the air. Let's consider representatives of this class in more detail.

Turtles

Turtles are The most famous among reptiles. They can dwell both on land and in water. They can be seen not only in the zoo and in the wild, many contain them at home. These cute animals do not represent any danger to a person, they are harmless.

Turtles appeared about two hundred million years ago. These reptiles have a shell. He protects them from enemies. It consists of two parts: abdominal and dorsal. From above, it is covered with a horny cloth in the form of plates.

These animals have a different size. There are giant turtles that can reach 900 kilograms. And there are small turtles. Their mass does not exceed 125 grams, and the length of the shell is only ten centimeters.

Instead of teeth, this animal has a powerful beak. With it, it crushes food.

At the habitat, the turtles are divided into:

• Freshwater: painted or decorated, European marsh, red, kayman;
• Sea: Biss Turtle, Leather, Green or Soup;
• Ground;
• Land: elephant, Egyptian, Central Asian, leopard, capskaya;

What these animals eat. Their food is completely dependent on their habitat. Ground turtles are powered by fruits, vegetables, trees branches, mushrooms and grass. And sometimes they can even eat worms and snails.

Water turtles feed on fine fish, shrimps, squid, frogs, snails, mollusks, insects, bird eggs.

Land turtleswho live at home feed on cabbage, apples, tomatoes, swear, cucumbers, dandelions, chicken eggs. And water home turtles love to be enjoyed with rainworms, boiled meat, a moth, insects, algae and lettuce leaves.

Turtle is a long-liver. She will survive any other representative of reptiles.

Crocodiles

Crocodile

The crocodile is the only representative of the subclass of Arkhozavrov. The length of their body is from two to seven meters. And the mass can reach more than 700 kilograms. Crocodile is a fairly fast animal in the water. Its speed can reach forty kilometers per hour.

The number of teeth in the crocodile ranges from 70 to 100. It depends on the type of crocodile. Teeth are long and sharp, about five centimeters.

These animals live only in warm countries with wet climat: Africa, Japan, Australia, Bali, North and South America, Guatemala, Philippine Islands.

Crocodile is a predator, so it feeds on fish, molluscs, birds, lizards, snakes, antilopes, deer, buffaloes, boars, dolphins, sharks, leopards, lions, hyenas. These animals can even eat monkey and dickery, kangaroo and bunny. And there are cases when crocodiles eat like that.

Live crocodiles for quite a long time - one hundred years.

Variety of crocodiles

Crocodiles are divided into three families: real crocodiles, gavial and alligator.

In turn, the crocodiles of the family of the present are divided into the following types:

The Alligators family is divided into:

• Missisipsky - differ from other species in that it can safely move the cold, having sinking all the body in the ice.
• Chinese, rare and small species of alligators. Its length does not exceed two meters, and it weighs only about forty-five kilograms.
• The crocodile Cayman is otherwise called the speaker crocodile. This is due to the fact that on his face between eyes there are highlights that resemble glasses.
• Black Cayman is pretty large view Alligator. Its length reaches 5.5 meters, and it weighs more than 500 kilograms.

The Gavial family is divided into:

• Ganga gavial. The length of his body reaches six meters, and it weighs only about two hundred kilograms.
• Gavial. The muzzle of this species is narrow and long. The body length is six meters, and the weight does not exceed 200 kilograms.

Gatteria

Most people believe that gatteria is lizard. But this is an erroneous opinion. This reptile lived in the era of dinosaurs and forms a detachment of the beakhead. This reptile has another name - Tuhatara.

They only live in New Zealand. In appearance, they resemble Iguan. Internally, it looks like a snake. Something they took from the turtles, and something from crocodiles.

She has one more feature - three eyes. The third eye is on the occipital part. The length of Gatteria reaches more than fifty centimeters, and it weighs not more than one kilogram.

This amazing animal leads only a nightlife. Slow motter breathing. She may not breathe whole sixty minutes.

This reptile feeds insects, snails, worms. Life expectancy is quite long, about a hundred years.

Lizards

Lizards belong to the class of reptiles. Their variety is very large - about six thousand species. All of them differ from each other with their size, painting, habitat.

Lizards are very similar to the triton, but they have many differences. One of the main differences is that Triton is an amphibious animal. And the amphibian animal differs from the reptile.

Almost all lizards have a feature. - This is the ability to drop your tail in emergency cases. Many lizards can change body color.

Food insect lizards: butterflies, snails, grasshoppers, spiders, worms. Large representatives Feed small animals, snakes and frogs.

Lizards are divided into six infrastructors:

• Scintoobrous;
• Iguano-shaped;
• Geco-shaped;
• Yerethenice-shaped;
• Worm-shaped;
• Varano-shaped

All these infrautors are divided into families. Scincrugs are divided into:

Iguano-shaped They are divided into fourteen families. The most vivid representative of this infrared is chameleon.

Geckeless They are divided into seven families. From which you can allocate an unusual lizard - this is a scaled. The peculiarity of this reptile is that she has no legs.

Verethenice-shaped It is divided into five families: the bells of the Varana, the spontaneous, a naked lizard, Varana, xenosaurs.

Draw-shaped lizards consist of one family. These reptiles look like rainworms.

Varano-shaped lizards Consist of several families. They are the biggest lizards. For example, the Komodsky Varan can weigh more ninety kilograms.

Snakes

Snake is a cold-blooded animalwhich refers to the class of reptiles. Weight and stem size is different. Their length can reach nine meters, and the weight of more than one hundred kilograms.

Snakes are poisonous and unseated. These reptiles are deaf. They are guided by language. It is he collects environmental information.

Feed snakes rodents, bird eggs, fish, and some eat even like themselves like. They eat food only twice a year.

Snakes are egg stand. Someone postphes ten eggs, and someone one hundred and twenty thousand eggs. Some representatives give birth to live cubs.

The variety of snakes is huge. They are numbered more than three thousand species.

The most interesting representatives are the following:

Now you know who are such reptiles or reptiles. And who is their representatives.
