Top 10 Most Dangerous Snakes in the World

Saw Scaled Viper, also known as Echis, is a venomous snake found in arid regions such as Africa, Pakistan, India, and Sri Lanka. Saw Scaled Viper is rarely seen during the day as they are nocturnal. The venom of this snake acts quite slowly, so victims of snakebites often take a long time to seek treatment. The diet of Echis is quite diverse, including various species of grasshoppers, beetles, worms, snails, spiders, scorpions, centipedes, frogs, lizards (including snakes), small mammals, and birds.

Echis is a genus of venomous snakes in the family Viperidae, mainly found in arid regions of Africa, the Middle East, India, and Sri Lanka. Victims of their bites account for a large proportion of snakebite deaths worldwide. A characteristic of this snake is that when in danger, they rub their body parts together to produce a hissing sound. Their venom consists mainly of haemotoxins. Victims of this toxin quickly die because haemotoxins destroy red blood cells, causing blood clotting disorders leading to multiple organ failure and death.

The Tiger Snake Family is a family of snakes belonging to the suborder Serpentes in the branch Ophidia. Traditionally, it only includes venomous snakes living on land, but recently it has been expanded to include sea snakes as well. As of April 2019, 371 species are recognized in this family. The tiger snake is an extremely venomous snake found in the southern regions of Australia. It is easily recognizable by the prominent bands on its body. When bitten, you will feel pain and itching around the bitten area, initially experiencing difficulty breathing, which gradually leads to paralysis. According to research, the mortality rate when bitten by a tiger snake without timely treatment is 40-60%.

All tiger snake species have a pair of fangs in the front to inject venom from glands located behind the upper jaw. Outwardly, land-dwelling tiger snakes resemble water snakes (Colubridae): almost all have slender bodies with smooth scales, heads covered with large shields that are not always distinguishable from the neck, and round pupil eyes. Additionally, their behavior is often quite aggressive, and most are egg-laying species. There are also exceptions to these generalizations including slow-moving ambush predators, short and stout, rough-scaled, very broad heads, cat-like eyes, live-bearing, prey-hunting with partially fragmented head shields.

The Philippine Pit Viper is commonly found in the northern islands of Luzon, Mindoro, Catanduanes, Azria, and Masbate of the Philippines. It's highly venomous, with an average length of about 1 meter, and particularly fond of water, often found near ponds, rivers, or large puddles. Its diet consists mainly of small mammals, frogs, other snake species, and mice. Given the opportunity, it will also prey on small birds. This species is easily recognizable by the white stripes on its body.

The Philippine Pit Viper, or the Philippine venom-spitting snake, is a short, highly venomous species of pit viper native to the northern regions of the Philippines... This species was first described by Taylor in 1922. It is the second most venomous snake in the true pit viper genus (Naja) after the Caspian cobra. Just hearing about it gives you goosebumps, doesn't it?

The Malayan Krait is a species of the cobra family. This species is mainly distributed in the lowlands of countries such as Cambodia, Indonesia, Malaysia, Singapore, Thailand, and Vietnam. They can live in bushes, piles of bricks, mouse holes, and even inside houses. They appear docile during the day but dominate at night. The venom of the Malayan Krait mainly consists of neurotoxins that cause neurological paralysis. When bitten, victims often experience severe abdominal pain accompanied by paralysis. After 4-8 hours, victims may die if not treated promptly, with the main cause of death being respiratory failure.

The Malayan Krait lives in various habitats, from hills, sparse forests, grasslands, stream banks to rice fields. They live in termite mounds, animal burrows, tree hollows, and rock crevices. Malayan Kraits are solitary and usually curl up during the day, often very slow-moving. They are often seen during rainy weather. At night, they become active and forage near forest edges, stream banks, and water pools. Kraits do not actively hunt but rather lie in wait for prey to pass by. They are good swimmers and often follow light sources. Their main food source is other snakes, but they sometimes eat fish, frogs, and snake eggs.

Black Mamba Snake is commonly found in the Sahara Desert in Africa, it is the most dangerous snake in Africa, and residents there often avoid encountering them as much as possible, hence they call this snake the 'kiss of death'. True to its name, this snake is jet black, with smooth and flat scales. The Black Mamba can move at an astonishing speed - 20 km/h, with this speed, it outranks the top spot in the world of snakes. Its venom is extremely dangerous, causing unconsciousness within 45 minutes of being bitten, and if not treated promptly, death can occur within 7 - 15 hours.

Black Mambas reproduce annually. The mating season takes place in early spring. The female snakes lay eggs after being pregnant for more than 80 to 90 days. Young black mambas are lighter in color than adults and darken as they age. Although mambas are typically arboreal snakes, Black Mambas only occasionally live in trees, preferring to build burrows on the ground. Black Mambas inhabit a variety of terrains from dry grasslands, sparse forests, rocky hillsides to dense forests. They are diurnal animals, mostly hunting during the day, preying on small mammals, rock hyraxes, and other small vertebrates. Adult Black Mambas have a few natural predators hunting them in the wild.

Inland Taipan Snake is a native species of Australia and is considered the most venomous snake in all land snakes based on the LD50 index. It is a snake species belonging to the Elapidae family. Despite being venomous, it is very shy and secretive, always trying to flee if disturbed. It has a dark brown or olive-green color depending on the season and can grow up to 1.8 meters in length, with a maximum of 2.5 meters. It preys on small mammals and birds. Its habitat is central Australia, from southeastern Northern Territory to western Queensland. It also inhabits the northern Eyre basin and to the west of the Murray, Darling, and Murrumbidgee rivers.

Inland Taipan Snake is an extremely venomous snake, often found in arid regions of central eastern Australia. Its color changes with the seasons, lighter in summer and darker in winter, allowing it to absorb more light when it's cold. When bitten by an Inland Taipan, the victim initially feels headaches, nausea, dizziness, abdominal pain, diarrhea, convulsions leading to blood clotting disorders, and potentially fatal muscular paralysis.

Pseudonaja is a genus of venomous elapid snakes native to Australia. Species within this genus are often referred to as brown snakes and are considered some of the most dangerous snakes in the world; even bites from juveniles can be fatal. Despite the common name, the Eastern Brown Snake is not a true brown snake but a member of the genus Pseudechis, often referred to as black snakes. Brown snakes are highly nervous and may bite if approached closely, handled, or threatened. Sudden collapse, often early, is a characteristic sign of envenomation by them. A notable effect of their venom is coagulopathy due to consumption of venom, which can lead to death. Renal failure may also rarely occur.

Through experiments on mice, this brown snake species was found to contain the second-highest toxicity among land snakes in the world and primarily contains neurotoxic venom. Classified as one of the most dangerous snakes in the world not only because of its venom but also because it is a combative, attacking species. They can be found in Australia, Indonesia, Papua New Guinea, but they can live anywhere, from densely populated areas to remote regions. Their primary food includes rodents such as house mice, as well as frogs, small birds, eggs, and other snake species. When bitten, victims may experience diarrhea, dizziness, severe convulsions, renal failure, paralysis, and cardiac arrest.

Rattlesnakes, also known as bell snakes or rattlers, are a group of venomous snakes belonging to the genera Crotalus and Sistrurus of the subfamily Crotalinae (the 'pit vipers') with the shared characteristic of their tails capable of rattling and producing a warning sound when hunting prey or sensing danger. There are 32 species of rattlesnakes with about 65-70 subspecies, all native to the Americas, ranging from southern Canada to central Argentina. Most rattlesnakes are highly venomous. Their venom can quickly paralyze the nervous system of prey such as mice, birds, and some other small animals, ultimately causing the victim's heart to stop beating within minutes of being bitten.

Rattlesnakes originated in the Americas, inhabiting diverse environments from southwestern Canada to central Argentina. Their name comes from the distinctive feature of their appearance, the rattling sound produced by their tails when in motion, resembling a small bell, hence the name rattlesnake. These snakes typically prey on mice, birds, and small animals. Rattlesnake venom is potent, causing tissue destruction and coagulation disorders. They will not attack indiscriminately unless threatened first. With prompt medical treatment, rattlesnake bites are usually not fatal.

Death Adder is a genus of the family Elapidae. They originate from Australia, New Guinea, and nearby islands, and are among the most venomous snakes in the world. The name of this genus is derived from the ancient Greek akanthos, referring to the spine on the tail of the deceased. Seven species are listed by ITIS, although the exact number of species remains uncertain, with figures ranging from 4 to 15 species cited.

Death Adders are native to Australia, being the deadliest land snake in Australia and globally. They have a stout body with bands of red, brown, black, and gray. Death Adders are masters of camouflage, often hiding beneath loose leaf litter and debris in forests, bushlands, and grasslands. Their primary prey includes birds and small mammals. Bites from this snake cause neurological paralysis, and if not treated, victims may die within about 6 hours after being bitten.

Acanthophis là một chi của họ Rắn hổ. Chúng có nguồn gốc từ Úc, New Guinea và các đảo lân cận, và là một trong những loài rắn độc nhất trên thế giới. Tên của chi này bắt nguồn từ tiếng Hy Lạp cổ đại akanthos, đề cập đến cột sống trên đuôi của người chết. Bảy loài được liệt kê bởi ITIS, mặc dù vẫn chưa rõ có bao nhiêu loài này bao gồm, với số liệu từ 4 đến 15 loài được trích dẫn.

Rắn tử thần có nguồn gốc từ Úc, là loài rắn đất độc nhất ở Úc và trên toàn cầu. Có cơ thể dày với các dải màu đỏ, nâu, xanh đen và xám. Rắn tử thần là một bậc thầy về thuật ngụy trang, chúng thường giấu mình dưới các đống lá lỏng lẻo và các mảnh vụn ở trong rừng, bụi cây và trảng cỏ. Thức ăn chính của chúng là chim và các động vật có vú nhỏ. Các vết cắn của loài rắn này gây tê liệt thần kinh và sau khi bị cắn khoảng 6h nếu không được chữa trị, nạn nhân sẽ bị tử vong.

The ocean harbors numerous snake species, but none more venomous than the Belcher's sea snake, with a slender body, usually yellowish or dark green, often found offshore in the northern coast of Australia and Southeast Asia. Possessing extremely potent venom, just a few milligrams can kill thousands of people, but fortunately, like most other sea snakes, the Belcher's sea snake is relatively harmless and avoids contact with humans, only striking when feeling threatened. If unlucky enough to be bitten by this snake, although the wound may not cause significant pain, do not underestimate it; seek medical attention immediately, as death can occur within 30 minutes after being bitten.

Belcher's sea snake has a moderate size, ranging from 0.5 to 1 meter. Their slender body is typically chrome-yellow with dark greenish veins. The dorsal color pattern does not extend onto the belly. They have short heads with uniformly colored bands. Their mouths are very small but suitable for aquatic life. The body color, when viewed out of the water, appears a pale yellow. Their scales differ from most other snake species in that they overlap. Each dorsal scale has a ridge in the center. Their bodies are strongly compressed toward the rear. Their ventral scales are very narrow, only slightly wider than the dorsal scales. This species is reclusive and typically only bites humans under severe provocation. Typically, those bitten are fishermen handling nets, although only about a quarter of those bitten are envenomated, as this snake rarely injects its venom.
