There are more than 3, species of snakes in the world and there is at least one type of snake on every continent except Antarctica. While the snake has a bad rap as a pest, snakes can often be quite helpful and even a fun pet. With so many different species, there are snakes of many different sizes. The world's smallest snakeaccording to National Geographic, is the thread snake, which grows to only about 3. It looks much like an earthworm.
The largest snake, the reticulated python, can grow to a whopping 30 feet 9 meters. The largest snake fossil ever discovered is called the Titanoboa. This creature lived 60 million years ago and would have been 50 feet 15 meters long. It is a common misconception that snakes build nests for their eggs. Only one species of snake, the king cobra, will build a nest for its young.
Not all snakes lay eggs, either. About 70 percent of snakes lay eggs. These types of snakes are called oviparous. The other 30 percent give birth to live young, much like mammals. This is because some climates are too cold for eggs to develop and hatch, so snakes living in colder climates do not lay eggs.
Snakes are carnivores. This means that they only eat meat. Snakes are often seen as pests, but they actually can help keep pests at bay by eating rodents. Many people think that all snakes kill their prey by biting it and injecting the prey with poison. This isn't true. Cobras, vipers and other related species are the only snakes that use venom to hunt.
Most snakes simply swallow their prey whole. Large snakes, such as the python, will strangle their prey to death and then swallow it whole.
Snakes can eat other animals 75 to percent bigger than their own size, according to National Geographic. They have been known to eat animals such as crocodiles and cows.Snake venom comes in different types. Different types of venom have different effects on humans. Cytotoxic Venom destroys tissue and causes pain, swelling and eats away at the flesh.
Cytotoxic bites varie in potency according to the species of snake, size of the snake and the amount of venom injected. Tissue damage will occur and without antivenom death may follow. There are species of Viper whose venom does not cause such severe symptoms and antivenom is not usually needed and is often not produced as the symptoms of the bite are not severe enough to warrant the time and money it takes to produce antivenom.
Neurotoxic Venom is very dangerous and bites will cause drowsiness, blurred vision, difficulty speaking and eventually paralysis which causes your lungs to stop working. Neurotoxic venom is very fast acting. If you get bitten antivenom will usually be needed, patients may also have to be put on life support if antivenom is not available or if they are not treated quick enough.
Heamotoxic venom stops blood from clotting causing internal bleeding. The bite site will start bleeding and the person will start to bleed from small cuts and mucus membranes. The person will also have headaches, nausea and may start to vomit.
Death may occur if antivenom is not administered. Snakes which have heamotoxic venom include: the Boomslang a back fanged snake from Africa and the Vine Snake. Some snakes have a combination of different venom types for example the Berg Adder. I have not used the term victim in this article as snakes only bite people in self-defence. People are most likely to get bitten trying to pick up a snake or to kill a one.
Need Help? Call Now! Types of Snake Venom and their Effects on Humans.Snake venom is the poisonous, typically yellow fluid stored in the modified salivary glands of venomous snakes. There are hundreds of venomous snake species that rely on the venom they produce to debilitate and immobilize their prey.
Venom is composed of a combination of proteins, enzymes, and other molecular substances. These toxics substances work to destroy cells, disrupt nerve impulses, or both.
Snakes use their venom cautiously, injecting amounts sufficient to disable prey or to defend against predators. Snake venom works by breaking down cells and tissues, which can lead to paralysis, internal bleeding, and death for the snake bite victim.
For venom to take effect, it must be injected into tissues or enter the bloodstream. Snake venom is the fluid secretions from the modified salivary glands of venomous snakes. Snakes rely on venom to disable prey and aid in the digestive process. The primary component of snake venom is protein. These toxic proteins are the cause of most of the harmful effects of snake venom. It also contains enzymeswhich help to speed up chemical reactions that break chemical bonds between large molecules.
These enzymes aid in the breakdown of carbohydratesproteins, phospholipidsand nucleotides in prey.
Snake Facts & Types of Snakes
Toxic enzymes also function to lower blood pressure, destroy red blood cells, and inhibit muscle control. An additional component of snake venom is polypeptide toxin. Polypeptides are chains of amino acids, consisting of 50 or fewer amino acids. Polypeptide toxins disrupt cell functions leading to cell death.
Some toxic components of snake venom are found in all poisonous snake species, while other components are found only in specific species. Although snake venoms are composed of a complex collection of toxins, enzymes, and non-toxic substances, they have historically been classified into three main types: cytotoxins, neurotoxins, and hemotoxins. Other types of snake toxins affect specific types of cells and include cardiotoxin, myotoxins, and nephrotoxins. Cytotoxins are poisonous substances that destroy body cells.
Some tissue may experience liquefactive necrosis in which the tissue is partially or completely liquefied. Cytotoxins help to partially digest the prey before it is even eaten. Cytotoxins are usually specific to the type of cell they impact.Personality of the Snake.

Snake people of O-type blood are mellow, sophisticated, polite and considerate yet unapproachable, sharp-witted and suspicious. They don't trust people and things around and would rather hide away their ability than show it, making others feel mysterious. O-type Snakes are strong-minded and struggle quietly to stand out.
They act as if nothing were on their minds but are actually determined to achieve their goals. Highly self-esteemed and jealous, they never admit defeat but strive for the best at any time. Of course, they are mostly good-natured and kindhearted and never hurt others.
Though they are very polite and courteous, O-type Snakes are apparently unapproachable because they are suspicious and unwilling to express their inner world. Also, they are vain and hate to be surpassed; otherwise, they will feel bad and become vindictive, even towards their friends, colleagues and old classmates. They hate those with great achievements and would revenge by fair means or foul without a trace, thus lonely for the whole life.
As for love, Snakes of O-type blood are very possessive and would make every endeavor, even play hard to pursue the one they love. After marriage, they disallow their partners to make any mistake and hate the extramarital affair bitterly. Though obsessed and loyal to love, they are quite suspicious and sometimes don't trust their partners at all, even follow or wiretap, which hurt their love mentally and make themselves feel bad. O-type Snake people should be more broad-minded and less jealous.Mi note 4 sim ic jumper

Auspicious Chinese Names.Modern reptiles do not have the capacity for the rapid sustained activity found in birds and mammals. It is generally accepted that this lower capacity is related to differences in the circulatory and respiratory systems. Before the origin of lungsthe vertebrate circulatory system had a single circuit: in the fishesblood flows from heart to gills to body and back to the heart.
The heart consists of four chambers arranged in a linear sequence.Pigeon wikipedia
With the evolution of lungs in early tetrapodsa new and apparently more efficient circulatory system evolved. Two chambers of the heart, the atrium or auricle and ventriclebecame increasingly important, and the beginnings of double circulation appeared.
An early stage in this evolution can be seen in amphibians today, where one of the main arteries from the heart the pulmonary artery goes directly to the lungs, whereas the others the systemic arteries carry blood to the general body. In amphibians the blood is aerated in the lungs and carried back to the atrium of the heart. From the left side of the atrium, which is at least partially divided, the aerated blood is pumped into the ventricle to mix with nonaerated blood; nonaerated blood from the body is returned to the heart via the right half of the atrium.
Then the cycle begins again. One aspect of the amphibian system is that the blood leaving the heart for the body is only partially aerated; part of it is made up of deoxygenated blood returned from the body. All groups of modern reptiles have a completely divided atrium ; it is safe to assume, therefore, that this was true of most, if not all, extinct reptiles. In the four major living groups of reptiles, the ventricle is at least partially divided.
As pressure builds up in that chamber, the nonaerated blood is forced through the gap in the partition into the right chamber of the ventricle. Then, when the ventricle contracts, nonaerated blood is pumped into the pulmonary artery and thence to the lungs, whereas aerated blood is pumped into the systemic arteries the aortas and so to the body.
In snakes all three arterial trunks come out of the chamber of the ventricle that receives the nonaerated blood of the right atrium. During ventricular contraction a muscular ridge forms a partition that guides the nonaerated blood into the pulmonary artery, while the aerated blood received by the other chamber of the ventricle is forced through the opening in the ventricular septum and out through the aortas.
In crocodiles the ventricular septum is complete, but the two aortas come out of different ventricular chambers. A semilunar valve at the entrance to the left aorta prevents nonaerated blood in the right ventricle from flowing into the aorta.
Instead, part of the aerated blood from the left ventricular chamber pumped into the right aorta flows into the left by way of an opening. The ventricle of the turtle is not perfectly divided, and some slight mixing of aerated and nonaerated blood can occur.
Despite the peculiar and complex circulation, lizards, snakes, and crocodilians have achieved a double system. Tests of the blood in the various chambers and arteries have shown that the oxygen content in both systemic aortas is as high as that of the blood just received by the left atrium from the lungs and is much higher than that of the blood in the pulmonary artery.
Except for the turtles, limitation of activity in reptiles cannot be explained on the basis of heart circulation. An explanation may lie in the chemistry of the blood. The blood of reptiles has less hemoglobin and thus carries less oxygen than that of mammals.
The form of the lungs and the methods of irrigating them may also influence activity by affecting the efficiency of gas exchange. In snakes the lungs are simple saclike structures having small pockets, or alveoli, in the walls. In the lungs of all crocodiles and many lizards and turtles, the surface area is increased by the development of partitions that, in turn, have alveoli.
10 Unknown Health Benefits of Drinking Snake Blood
Because exchange of respiratory gases takes place across surfaces, an increase of the ratio of surface area to volume leads to an increase in respiratory efficiency. In this regard the lungs of snakes are not as effective as the lungs of crocodiles. The elaboration of the internal surface of lungs in reptiles is simple, however, compared with that reached by mammalian lungs, with their enormous number of very fine alveoli. Most reptiles breathe by changing the volume of the body cavity.
By contractions of the muscles moving the ribs, the volume of the body cavity is increased, creating a negative pressure, which is restored to atmospheric level by air rushing into the lungs.
By contraction of body muscles, the volume of the body cavity is reduced, forcing air out of the lungs. This system applies to all modern reptiles except turtleswhich, because of the fusion of the ribs with a rigid shell, are unable to breathe by this means; they do use the same mechanical principle of changing pressure in the body cavity, however. Contraction of two flank muscles enlarges the body cavity, causing inspiration. Contraction of two other muscles, coincident with relaxation of the first two, forces the viscera upward against the lungs, causing exhalation.
