10 Most danger Snakes


Without an inch of doubt, snakes tend to rank high among all that we shall be scared of. For the simple reason that they are among the deadliest and most toxic living beings, snakes have as much beauty of creation as any other animal.

1. The Belcher’s Sea Snake
Also known as the Faint-banded Snake. This reptile was christened John Edward Gray after the legendary explorer, Sir Edward Belcher. The Belcher is by nature quite and amiable, found mostly in the coastal areas near Philippines. The Belcher snake has a poison, which is around 100 times stronger than the Inland Taipan. However, the snake is not known to deliver a lethal dose every time.

2. The Inland Taipan
It is by default a local of the deserts of Australia. The snake is known to be docile, and coy, which should be good news, for its default venom is strong enough to deliver a fatal blow to around hundred full grown humans. Venom around four hundred times stronger than that of a Cobra.

3. The Beaked Sea Snake
Another big time exploit in world of snakes. This snake is known for its venom and is spotted around the rim of the Persian Gulf up to those of Australia without fail. A dig of this reptile has enough power to kill 10 men. Also this snake is known for biting without aggravation and is to blame for almost half of all sea snake bites and most of the deaths thereafter.

4. Krait
It is known for its venom which happens to be around fifteen times stronger than that of a cobra. There are accidents of people being bitten by this snake when they end up surprising it. Mostly, because the krait may take a shelter in domestic civil areas.

5. The Philippine Cobra
By the very implication of its name is found on Philippines Islands and has a way of flaring its hood. This way of the cobra has given it a special category among snake charmers.

6. The Indian King Cobra
It is simply the largest of the venomous as it can take on a length up to 13 feet in length and gain somewhere around 9 kilograms of weight. Though it does not come with the strongest of venoms, it sure does know the art of pumping a good quantity of its venom into its victim.

7. Russell’s viper
A lot many people consider the Russell’s viper as being the most venomous snake in Asia. Its high presence among civil population has made it quite a killer.

8. The Black Mamba
The Black Mamba found in Africa is not a high time man killer because of its nature, but because of the fact that its territory has been invaded by humans and also because it is found in some 14 nations world wide. In fact, besides being a poisonous snake, the black mamba is the fastest snake by all measures, which can reach a speed of around 20 kmph.

9. The Yellow-Jawed Tommy Goff
It is also known as the ‘Fer-de-lance’ is locally found in many areas of South America. This snake is reputed for having a very bad nature and severe temperament, which make this snake strike a very high, which is not matched by many snakes. There fangs seek heat patterns, an ability which makes them deadly at night hunts. Be it man, animal or simply fun.

10. The Multibanded krait
It is better known as the Many Banded or Taiwanese Banded krait will be the last mention in our list. The snake is mostly found in the Indian subcontinent. The venom of a multibanded krait is known to paralyze people before killing them.

10 Top Dangerous Snake Species


Snakes are very fearsome creatures, even those that are not that poisonous. However, since these slithery beings are associated with their killing power, which causes fear and panic to everyone, their existence brings terror to anyone who sees them. Check this list and see if you can survive the horror.

10. Jararacussu
Found hanging in the forests and trees of Argentina, Bolivia, Brazil, and Paraguay is the dark greenish Jararacussu. The color of its lower body has striking yellow, which makes it obvious on ordinary environments. With length growing to a maximum of over 3 meters, this snake has a lot of poisonous ammo with 800mg per bite, enough to kill 32 people in one shot.

9. Tiger Snake
Watch out when you are in the lands of Australia, particularly in Tasmania, Bass Strait islands, and New Guinea as there are Tiger Snakes that may be found in arid environments and in near human settlements on grassy areas and waterways. You cannot mistake its dark brown color with body that extends to a max length of 1.8 meters. It is known to be very aggressive when aggravated as it can produce poison from 35mg to 180mg per bite.

8. Multibanded Krait
You cannot misjudge this for a zebra, as a Multibanded Krait is a very poisonous snake that cannot be belittled. One comforting info about these snakes is that they are rarely found on land, but are usually tangled on fishnets, victimizing fishermen in the process. They feed on frogs, fish, and other snakes, which make them famous in islands like those found in the South China Sea, Vanuatu, and Fiji. Their Alpha-Bungarotoxin is one powerful neurotoxin that can knock down people.

7. Yellow Jawed Tommygoff
When you are living in farms and other cultivated lands, make sure that you do not have too many rodents at home as it may attract a Yellow Jawed Tommygoff to stay in one of your rooms. Also, be sure not to be too frantic when seeing one, even in the dark, as it has heat-seeking fangs that are accurate to the bite. When you are poisoned by its cytotoxic venom, expect that your skin, even tissues, will be burned in minutes.

6. Black Mamba
You cannot dance with this baby as Black Mamba is the fiercest of its species, even feared all over the continent of Africa. Despite being called Black, it can also be found in other shades of brown, olive, and even yellow green. Be sure to have an antivenin handy when you are venturing in dense forests, as its bite is 100% fatal when you do not treat its bite right away.

5. Russell’s Viper
Three rows of splotches, seeing it in a length of up to 1.5 meters is a sign that you are seeing the Russell’s viper, even close to death by the doors. It can be found in Sri-Lanka, Southern China, India, Malaysian Peninsula, Java, Sumatra, Borneo, dwelling in rain forests and farmlands. It is very irritable, thus it is encouraged not to bug it even a bit. Its hemotoxic venom can damage tissues and red blood cells upon contact.

4. King Cobra
The King Cobra has a disposition that goes well by its name. It is the biggest venomous snake in the world, plus it has wits in suppressing its anger from messing with other poisonous snakes, showing its superior intelligence. It grows very long averaging at 3.5 meters to 5.5 meters max, and can inject a large amount of neurotoxin in the system.

3. Philippine Cobra
Despite of being small, the Philippine Cobra is one of the most poisonous snakes to exist in this planet, even overpowering the King when it comes to its destructive power. Just imagine that with a length of only 100 centimeters max, it packs killing ammo that cannot be mistaken for something small fry. It can be both friendly to snake charmers and deadly by its own remark.

2. Common Indian Krait
The nocturnal Common Indian Krait is a very threatening concern, as its poison is 15 times stronger than that of a normal cobra. Be sure to guard your things when you are on camp as they find sleeping in tents, boots, and in bags, very pleasant. Its powerful neurotoxin cannot only cause poison, but it can also complicate breathing.

1. Inland Taipan
Taipan is a snake that is best described as death because of its very powerful venom that can kill people in just a couple of hours. It can inject over 110mg of toxin that can kill over 100 people and 250,000 mice in a single bite. They are often misunderstood as aggressive as they are very docile despite of their fame.

philippine cobra

The Philippine Cobra (Naja philippinensis) or "ulupong" in Tagalog is listed as "near threatened" in IUCN due to heavy persecution in some areas and widely trading of this species. They are endemic in Philippines, in Luzon, Mindoro, Masbate, and Marinduque which typically found in low level areas in moist forest to agricultural and urban areas.

The Philippine cobra is a stocky and very toxic snake. Its average length is 1.7 m and some grows up to 2 m. Its color is light to medium brown while the young cobra's color is a darker brown, sometimes a dark band behind the throat. They have 23 to 27 scale rows around the neck, 21 just above the middle part of the body, 182-193 ventrals, 36-49 subcaudals, basal pairs sometimes undivided . They prey upon mice, frogs and small mammals. The female lays eggs in clutches of ten to twenty with an incubation time of sixty to seventy days.The venom is a neurotoxin which affects cardiac and respiratory function and can cause neurotoxicity and respiratory paralysis and death in thirty minutes. The bite causes only minimal tissue damage. The Philippine cobra is capable of spitting their venom up to three meters.

These species is widely persecuted. collected for exotic food trade, for pet trade and collected for anti-venom production by Research Institute for Tropical Medicine (RITM). At present to conservation moves are made by any organization to protect the decreasing population of Philippine Cobra.
















Exploring Top 10 Venomous Snakes


Rattlesnake
Death Adder
The appropriately named Death Adder is found in Australia and New Guinea. They actually hunt and kill other snakes, including some on this list, usually via ambush. Death Adders look quite similar to vipers, in that they have triangular shaped heads and short, squat bodies. They typically inject around 40-100mg of venom with an LD of 0.4mg-0.5mg/kg. An untreated Death Adder bite is one of the most dangerous in the world. The venom is a neurotoxin. A bite causes paralysis and can cause death within 6 hours, due to respiratory failure. Symptoms generally peak within 24-48 hours. Antivenin is very successful in treating a bite from a Death Adder, particularly due to the relatively slow progression of symptoms, but before its development, a Death Adder bite had a fatality rate of 50%. With the quickest strike in the world, a Death Adder can go from strike position to striking and back again within 0.13 of a second.

Vipers
 Vipers are found throughout most of the world, but arguably the most venomous is the Saw Scaled Viper and the Chain Viper, found primarily in the Middle East and Central Asia, particularly India, China and South East Asia. Vipers are quick tempered and generally nocturnal, often active after rains. They are also very fast. Most of these species have venom that cause symptoms that begin with pain at the site of the bite, immediately followed by swelling of the affected extremity. Bleeding is a common symptom, especially from the gums. There is a drop in blood pressure and the heart rate falls. Blistering occurs at the site of the bite, developing along the affected limb in severe cases. Necrosis is usually superficial and limited to the muscles near the bite, but may be severe in extreme cases. Vomiting and facial swelling occurs in about one-third of all cases. Severe pain may last for 2-4 weeks. Often, local swelling peaks within 48-72 hours, involving the affected limb. Discoloration may occur throughout the swollen area as red blood cells and plasma leak into muscle tissue. Death from septicaemia, respiratory or cardiac failure may occur 1 to 14 days post-bite, or even later.

Philippine Cobra
 Most species of Cobra would not make this list; however the Philippine Cobra is the exception. Drop for drop, its venom is the most deadly of all the Cobra species, and they are capable of spitting it up to 3 metres. The venom is a neurotoxin which affects cardiac and respiratory function, and can cause neurotoxicity, respiratory paralysis and death in thirty minutes. The bite causes only minimal tissue damage. The neurotoxins interrupt the transmission of nerve signals by binding to the neuro-muscular junctions near the muscles. The symptoms might include headache, nausea, vomiting, abdominal pain, diarrhea, dizziness, collapse and convulsions.

Tiger Snake
 Found in Australia, the Tiger snake has a very potent neurotoxic venom. Death from a bite can occur within 30 minutes, but usually takes 6-24 hours. Prior to the development of antivenin, the fatality rate from Tiger snakes was 60-70%. Symptoms can include localized pain in the foot and neck region, tingling, numbness and sweating, followed by a fairly rapid onset of breathing difficulties and paralysis. The Tiger snake will generally flee if encountered, but can become aggressive when cornered. It strikes with unerring accuracy.

Black Mamba
 The feared Black Mamba is found throughout many parts of the African continent. They are known to be highly aggressive, and strike with deadly precision. They are also the fastest land snake in the world, capable of reaching speeds of up to 20km/h. These fearsome snakes can strike up to 12 times in a row. A single bite is capable of killing anywhere from 10-25 adults. The venom is a fast acting neurotoxin. Its bite delivers about 100–120 mg of venom, on average; however, it can deliver up to 400 mg. If the venom reaches a vein, 0.25 mg/kg is sufficient to kill a human in 50% of cases. The initial symptom of the bite is local pain in the bite area, although not as severe as snakes with hemotoxins. The victim then experiences a tingling sensation in the mouth and extremities, double vision, tunnel vision, severe confusion, fever, excessive salivation (including foaming of the mouth and nose) and pronounced ataxia (lack of muscle control). If the victim does not receive medical attention, symptoms rapidly progress to severe abdominal pain, nausea and vomiting, pallor, shock, nephrotoxicity, cardio toxicity and paralysis. Eventually, the victim experiences convulsions, respiratory arrest, coma and then death. Without antivenin, the mortality rate is nearly 100%, among the highest of all venomous snakes. Depending on the nature of the bite, death can result at any time between 15 minutes and 3 hours.

Taipan
 Another entry from Australia, the venom in a Taipan is strong enough to kill up to 12,000 guinea pigs. The venom clots the victim’s blood, blocking arteries or veins. It is also highly neurotoxic. Before the advent of an antivenin, there are no known survivors of a Taipan bite, and death typically occurs within an hour. Even with successful administration of antivenin, most victims will have an extensive stay in intensive care. It has been likened to the African Black Mamba in morphology, ecology and behavior.

Blue Krait
 The Malayan or Blue Krait is, by far, the most deadly of this species. Found throughout South East Asia and Indonesia, 50% of bites from the deadly Blue Krait are fatal, even with the administration of antivenin. Kraits hunt and kill other snakes, even cannibalizing other Kraits. They are a nocturnal breed, and are more aggressive under the cover of darkness. However, overall they are quite timid and will often attempt to hide rather than fight. The venom is a neurotoxin, 16 times more potent than that of a Cobra. It quickly induces muscle paralysis by preventing the ability of nerve endings to properly release the chemical that sends the message to the next nerve. This is followed by a period of massive over excitation (cramps, tremors, spasms), which finally tails off to paralysis. Fortunately, bites from Kraits are rare due to their nocturnal nature. Before the development of antivenin, the fatality rate was a whopping 85%. Even if antivenin is administered in time, you are far from assured survival. Death usually occurs within 6-12 hours of a Krait bite. Even if patients make it to a hospital, permanent coma and even brain death from hypoxia may occur, given potentially long transport times to get medical care.

Eastern Brown Snake
 Don’t let the innocuous name of this snake fool you, 1/14,000 of an ounce of its venom is enough to kill an adult human. Coming in a variety of species, the Eastern Brown snake is the most venomous. Unfortunately, its preferred habitat is also along the major population centers of Australia. The Brown snake is fast moving, can be aggressive under certain circumstances and has been known to chase aggressors and repeatedly strike at them. Even juveniles can kill a human. The venom contains both neurotoxins and blood coagulants. Fortunately for humans, less than half of bites contain venom and they prefer not to bite if at all possible. They react only to movement, so stand very still if you ever encounter one in the wild.

Inland Taipan
 While I did say that I would not include multiple sub-species in this list, the incredible Inland Taipan deserves a spot of its own. It has the most toxic venom of any land snake in the world. The maximum yield recorded for one bite is 110mg, enough to kill about 100 humans, or 250,000 mice! With an LD/50 of 0.03mg/kg, it is 10 times as venomous as the Mojave Rattlesnake, and 50 times more than the common Cobra. Fortunately, the Inland Taipan is not particularly aggressive and is rarely encountered by humans in the wild. No fatalities have ever been recorded, though it could potentially kill an adult human within 45 minutes.
