1. Top 8 Fastest Snakes in the World – Nature’s Speed Demons
Snakes are not only terrifying because of their venom or sophisticated hunting abilities, but also because of their incredible speed. In the wild, some snakes can dart like lightning to attack or escape. Let’s discover the world’s Fastest Snakes right here:
1.8. Black Mamba – Africa’s Fastest Moving Snake
- Kingdom: Animalia
- Phylum: Chordata
- Class: Reptilia
- Order: Squamata
- Suborder: Serpentes
- Family: Elapidae
- Genus: Dendroaspis
- Species: D. polylepis
Known for its slender, solid black body and astonishing speed, the Black Mamba (Dendroaspis polylepis) rightfully earns the title of “king of speed” on the African continent. This venomous snake is not only a terror to small animals but also commands respect from humans due to its lightning-fast attacks and extremely potent venom.
The most notable feature of the Black Mamba is its extraordinary speed. It can reach speeds of up to 20 km/h on the ground, equivalent to the speed of a moving bicycle. This ability allows the Black Mamba to easily chase down and overpower its prey, while also evading dangerous predators.
The venom of the Black Mamba is a formidable weapon, containing neurotoxins that can cause muscle paralysis and lead to death in just 20 minutes if not treated promptly. A single bite from a Black Mamba can inject enough venom to kill 10 adult humans.
1.7. Common Death Adder – Australia’s Fastest Striking Snake
- Kingdom: Animalia
- Phylum: Chordata
- Class: Reptilia
- Order: Squamata
- Suborder: Serpentes
- Family: Elapidae
- Genus: Acanthophis
- Species: A. antarcticus
Hiding in the dense forests and vast grasslands of Australia, the Common Death Adder (Acanthophis antarcticus) is one of the world’s most dangerous and agile snakes.
Though its size is modest, only 60cm to 1 meter long, the Death Adder possesses an extremely potent neurotoxin. In just a tenth of a second, this snake can inject its venom and return its jaws to an active striking position. And more than half of its venomous attacks on humans will result in death if left untreated.
1.6. Southern Black Racer – The World’s Fastest Non-Venomous Snake
- Kingdom: Animalia
- Phylum: Chordata
- Class: Reptilia
- Order: Squamata
- Suborder: Serpentes
- Family: Colubridae
- Genus: Coluber
- Species: C. constrictor
- Subspecies: C. c. priapus
The Southern Black Racer (Coluber constrictor priapus) is the world’s fastest non-venomous snake, widely distributed in the southeastern United States. Although it lacks venom, this snake still attracts the attention of nature observers for its speed and agility.
With an average length of 3 to 5 feet (about 0.9 to 1.5 meters), the Southern Black Racer can move quickly through grass, fields, and forests. It often hunts at night, preying on animals like mice, rabbits, and even other snakes.
The Southern Black Racer lives up to its “sprinter” title in the snake world. With the ability to move at up to 20 km/h, it can easily outrun prey or escape dangerous predators. This speed is achieved thanks to the Black Racer’s special body structure, with powerful muscles and a flexible spine that allow it to move gracefully over any terrain.
1.5. Yellow-bellied Sea Snake – The Fastest Snake Underwater
- Kingdom: Animalia
- Phylum: Chordata
- Class: Reptilia
- Order: Squamata
- Suborder: Serpentes
- Family: Elapidae
- Genus: Hydrophis
- Species: H. platurus
The Yellow-bellied Sea Snake (Hydrophis donaldi) is one of the most famous and unique sea snakes. Its scientific name is Pelamis, and it is widely distributed in the Pacific region, particularly in tropical and subtropical zones. The habitat of the yellow-bellied sea snake is in warm waters, from 16 to 30 degrees Celsius.
The yellow-bellied sea snake has a slender body, up to 3 meters long, which helps it move easily in the water. Its flattened tail acts like a paddle, creating a powerful thrust that allows the snake to move at an incredible speed of up to 15 miles/hour (24 km/h). This swimming ability helps the yellow-bellied sea snake travel long distances with ease, moving from one ocean to another and hunting effectively.
Another special point is that the skin of the yellow-bellied sea snake contains potent venom that can be fatal to humans. Although not as well-known as other sea snakes, the yellow-bellied sea snake deserves to be cared for and protected in nature.
1.4. King Cobra – The Snake with the Fastest Deadly Venom
- Kingdom: Animalia
- Phylum: Chordata
- Class: Reptilia
- Order: Squamata
- Suborder: Serpentes
- Family: Elapidae
- Genus: Ophiophagus Günther, 1864
- Species: O. hannah
Famous for its enormous size and extremely potent venom, the King Cobra (Ophiophagus hannah) deserves the title of “venom king” in the reptile world. This snake not only possesses a massive amount of venom, but its speed of venom injection is also incredibly fast, making it one of the most dangerous creatures on the planet.
The King Cobra is the world’s longest venomous snake, with a venom yield in a single bite that can be up to 7ml, enough to kill an African elephant in just a few hours and take a human life in only 30 minutes. Its venom contains extremely potent neurotoxins, capable of attacking the nervous system and muscles of its prey, leading to paralysis, respiratory failure, and rapid death.
Despite its large size, the King Cobra moves surprisingly fast. It can travel at speeds of up to 16 km/h, fast enough to chase and catch its prey. This combination of speed and powerful venom makes the King Cobra a successful hunter in its habitat.
1.3. Cottonmouth – The Fastest Striking Snake in the U.S. (Strike speed: 2.97 meters per second)
- Kingdom: Animalia
- Phylum: Chordata
- Class: Reptilia
- Order: Squamata
- Suborder: Serpentes
- Family: Viperidae
- Genus: Agkistrodon
- Species: A. piscivorus
Hiding in the swamps and stagnant ponds of the southern United States, the Cottonmouth (Agkistrodon piscivorus), also known as the water moccasin, is a dangerous predator with a lightning-fast strike. Its potent venom and perfect camouflage make the Cottonmouth a terrifying presence for many animals and even humans.
The Cottonmouth is famous for its astonishing speed when attacking prey. When it feels threatened, it can launch an attack in just 0.3 seconds, much faster than a human blink. Thanks to this extraordinary speed, the Cottonmouth can easily take down its prey before they have time to react.
The Cottonmouth’s venom, while not typically fatal to humans, can cause serious damage, including swelling, pain, necrosis, and even limb loss. Its venom contains substances that destroy cells and affect the blood clotting system, meaning that a bite can lead to dangerous complications if not treated promptly.
1.2. Rat Snake
- Kingdom: Animalia
- Phylum: Chordata
- Class: Reptilia
- Order: Squamata
- Suborder: Serpentes
- Family: Colubridae
- Subfamily: Colubrinae
The Rat Snake (Elaphe obsoleta), also known as the black snake or black rat snake, is a common species in North America. This snake is not only known for its large size and docile nature but also for its incredible speed, which makes it an effective hunter in its habitat.
Rat Snakes can move at speeds of up to 15 miles/hour (24 km/h) on the ground. This speed allows it to easily chase and catch its prey, which includes mice, squirrels, lizards, and small birds. The Rat Snake uses its slender and flexible body, along with its graceful wriggling ability, to move quickly through dense areas and climb trees with ease.
1.1. Sidewinder – The World’s Fastest Moving Snake
- Kingdom: Animalia
- Phylum: Chordata
- Class: Reptilia
- Order: Squamata
- Suborder: Serpentes
- Family: Viperidae
- Genus: Crotalus
- Species: C. cerastes
The Sidewinder (Crotalus cerastes), also known as the desert rattlesnake, is famous for its unique way of moving on sand, which makes it one of the world’s fastest snakes. Its sophisticated hunting skills and potent venom turn the Sidewinder into a formidable predator in the harsh desert environment.
The secret to the Sidewinder’s rapid movement lies in the special structure of the scales on its body. The scales on its belly are asymmetrically shaped, helping it move in a “sideways” gliding motion on the sand, which minimizes friction and increases speed. When it moves, the Sidewinder inclines its body to one side, forming an “S” shape and pushing the sand back with its belly scales. Thanks to this unique technique, the Sidewinder can reach speeds of up to 18 miles/hour (29 km/h) on sand, much faster than its prey and enemies.
The venom of the Sidewinder, while not typically fatal to humans, can cause serious harm, including swelling, pain, necrosis, and even limb loss. Its venom contains substances that destroy cells and affect the blood clotting system, meaning that a bite can lead to dangerous complications if not treated promptly.
