The 9 Fastest Venomous Snakes, Ranked

A highly venomous snake is hazardous, but what is even more so? What about one that is incredibly quick as well? Snakes move ahead with ease, propelled by their powerful muscles and loose skin; many of them have to move quickly to get food. Aside from their incredibly swift slithering speed, certain snakes may attack at a high velocity. Both will be on this list. See what makes these nine deadly snakes so swift by looking at their speeds!

Common Death Adder

Originating in Australia, the highly venomous common death adder can be found along the eastern and southern coasts of the continent. Grasslands, heaths, forests, and woods are typical habitats for this species. The heads of common death adders are characterised by their wide, flat, triangular shape. They grow to be two to three feet long and have somewhat substantial bodies. The bodies of these snakes are striped with bands of brown, red, grey, black, cream, and light pink. They are experts at camouflage, hiding beneath mounds of loose leaves and other detritus because of these earth tones.

The common death adder is a member of the Elapidae family of snakes, but unlike most of its relatives, it waits for its prey. It can really wait for a few days to find the ideal victim. It attacks fast, injecting its lethal venom, then waits for its prey to pass away before devouring them. Despite its lack of aggression, this ambush predator occasionally preys on humans and does not back down in the face of fear.

Australia boasts one of the fastest strikes in the world, if not the fastest, from the common death adder. In little than 0.15 seconds, it can inject its poison into gullible victims.Although they can’t move across terrain rapidly due to their stocky bulk, they make up for it with their amazing striking timing.


Agkistrodon piscivorus is the scientific name for the cottonmouth snake, though it goes by many other names. This is a native pit viper from the Southeast of the United States, where it’s well-known for its painful bites and semiaquatic habits. Usually, these snakes range in length from two to three feet. But some have grown longer than five feet, particularly in the eastern portion of their range. Cottonmouths have blunt snouts and distinctive skulls. Nearly 80% of the individuals are black, with brown, grey, olive, and tan colour patterns. In addition, they have crossbands that range from dark brown to black, with the colours more striking in juveniles.

This species is found in the country’s southeast and is frequently found near bodies of water, including lakes, ponds, creeks, and marshes. They tend to stay out of cold, deep water and prefer shallow places. This species is also found in forests, pine woodlands, and thickets of palmetto.

Compared to copperheads, cottonmouths can cause more severe injuries due to their potent cytotoxic venom. It isn’t as strong as rattlesnake venom, though.The cottonmouth is renowned for moving quickly—it can cover more ground than nine feet per second.They can only move this quickly in brief spurts, though.

Western Diamondback Rattlesnake

The southwestern regions of the United States and Mexico are home to western diamondback rattlesnakes. Some of these deadly vipers can grow up to six feet in length, although most develop to be between four and five feet long. They are renowned for their diamond-shaped patterns and are among the biggest types of rattlesnakes. These snakes have a grayish-brown colour and a dusty appearance. However, they can also be red, white, yellow, or pinkish-brown.

This species can be found in a range of environments, including as pine woods, rocky canyons, coastal plains, deserts, and grasslands with scrub. They aggressively hunt small rodents and birds, or they wait to ambush them. Moreover, they are among the rare kinds of snakes that may scrounge for food.

Short bursts of two to three miles per hour are possible for western diamondback rattlesnakes while they are running away or chasing prey.This is swift by snake standards, yet the typical person could easily outpace this species. But since they don’t attack on the offensive, these rattlesnakes won’t try to chase you.

Yellow-Bellied Sea Snake

With the exception of the Atlantic Ocean, venomous tropical ocean waters are home to the peculiar and eye-catching yellow-bellied sea snake. These snakes have brown backs and yellow bellies, along with other modifications that help them survive in the ocean. They have valved nostrils and a special paddle tail for swimming. Even though they live in saltwater, they need freshwater to drink, which is found as precipitation on the ocean’s surface.

This species hunts by swimming backward, lunging quickly, and floating on the surface. They also have strong venom.These snakes can dive, run from harm, and seize prey at high speeds in a split second.

Eastern Brown Snake

The eastern brown snake, which is native to Australia and New Guinea, is a thin, extremely venomous snake that can reach a length of seven feet. Their undersides are cream in colour and range from pale brown to black. This species can be found in many different types of habitats, such as fields, savannah woodlands, grasslands, and the periphery of metropolitan areas. In dense forests, they are not present.

One of the world’s most venomous snakes is the eastern brown snake. Their venom can cause cardiac arrest because it affects the circulatory system.

These lone snakes may outrun a human sprinter due to their extreme speed.While humans average six to eight miles per hour, eastern brown snakes may reach an astounding top speed of twelve miles per hour.

King Cobra

Despite its name, this poisonous snake is native to Asia and is not a real cobra. With a maximum length of 10 to 13 feet, king cobras are the longest venomous snakes in the world and belong to their own genus. Although this species is widely distributed, it is rarely frequently encountered in the wild.

As apex predators, king cobras consume other snakes. They use their flexible jaws to consume their victims whole after injecting them with poison.

One of the world’s fastest snakes, the king cobra can go up to 12 miles per hour. King cobras prefer to use their swift reflexes to get away from danger even though they are able to defend themselves.

Black Mamba

Black mambas are indigenous to sub-Saharan Africa and are members of the Elapidae family. This species, which may reach lengths of 6 to 9 feet, is the second longest venomous snake behind the king cobra. Nonetheless, reports of some have reached up to 15 feet.

These snakes can strike their prey at a considerable distance and are extremely deadly. They can also give several quick bites at once.With a top speed of 12.5 mph, black mambas are among the world’s fastest venomous snakes.


The sidewinder, a pit viper belonging to the rattlesnake family, is also referred to as the horned rattlesnake. It is indigenous to the deserts of northwest Mexico and the southwest United States.

It moves on the slick sand in an unexpected manner, giving it its name: sideways. Although venomous, the venom produced by this species is not as strong as that of other rattlesnakes.With their special gait and sandy habitat, sidewinders may reach speeds of up to eighteen miles per hour!

Gaboon Viper

The sub-Saharan African savannahs and rainforests are home to the intriguing-looking goboon viper. With the longest 2-inch fangs of any snake species and the largest venom production, gaboon vipers are truly remarkable.

In contrast to the Gaboon viper’s placid demeanour and slow movement, this species moves quickly.The Gaboon viper has a striking velocity of 175 to 200 miles per hour.The Gaboon viper is probably the world’s fastest-striking snake, albeit this isn’t confirmed by studies yet.
