King Cobras – The Largest Venomous Snake in the World

King Cobras are one of the most fascinating and feared snakes in the world. They are the largest venomous snakes, and their size and aggressive nature make them a formidable predator. Here, we will take an in-depth look at how big king cobras can get, their characteristics, and why they are considered one of the deadliest snakes in the world.

King Cobra Size

King Cobras are the longest venomous snake in the world, with an average length of 10 to 13 feet (3 to 4 meters). However, some specimens have been found to be as long as 18 feet (5.5 meters). They can weigh up to 20 pounds (9 kilograms), with males being larger than females.

King Cobras are also known for their distinctive hood, which they use to intimidate predators or prey. When threatened, they raise up to one-third of their body vertically and spread their hood to appear larger and more dangerous.

Benefits of King Cobra Size

The size of the king cobra provides several benefits. First, their large size allows them to take down larger prey, such as rodents, birds, and other snakes. They are also less vulnerable to predators due to their size. Additionally, their size allows them to intimidate potential predators and avoid confrontation.

King Cobra Vs Other Snakes

Compared to other venomous snakes, the king cobra is significantly larger. For example, the average length of a rattlesnake is around 3 to 4 feet (1 to 1.2 meters), while the average length of an eastern diamondback rattlesnake is around 6 feet (1.8 meters). This makes the king cobra a more formidable predator and a more significant threat to humans.

Characteristics of King Cobras

King Cobras are unique in several ways. They have a distinctive coloring, with a brown or olive color on their back and a yellow or cream-colored belly. They also have a large, flattened head and a long, slender body.

King Cobras are also known for their venom, which is one of the most potent among all snake species. Their venom consists of neurotoxins and cardiotoxins, which affect the nervous system and the heart, respectively. A single bite from a king cobra can kill an adult elephant.

King Cobra Venom and Humans

While king cobras are not aggressive towards humans, they will defend themselves if threatened. If bitten by a king cobra, a human will experience symptoms such as pain, swelling, and necrosis. If left untreated, a bite can lead to death within a few hours.

King Cobra in the Wild

King Cobras are found in Southeast Asia and parts of India. They prefer to live in dense forests, near water sources such as rivers and streams. They are solitary animals, and males and females only come together during the mating season.


In conclusion, King Cobras are the largest venomous snakes in the world, with an average length of 10 to 13 feet (3 to 4 meters) and a weight of up to 20 pounds (9 kilograms). Their size, distinctive hood, and potent venom make them one of the most formidable predators in the animal kingdom. While they are not aggressive towards humans, they should be treated with caution and respect in the wild.

Environmental factors such as food availability, temperature, and humidity can influence their growth rate, and they can grow larger in captivity than in the wild.

How big are King Cobra hatchlings?

King Cobra hatchlings are relatively large compared to other snake species, measuring between 45 and 60 centimeters (18 to 24 inches) in length at birth. They are also born venomous and can hunt and defend themselves from predators from an early age.

Despite their relatively large size, King Cobra hatchlings are vulnerable to predation and face many challenges during their first months of life.

What is the largest recorded King Cobra?

The largest recorded King Cobra was found in the wild in 1937, and it measured 5.85 meters (19.2 feet) in length. This specimen was caught and kept in captivity, where it lived for several years before dying of unknown causes.

How do King Cobras compare in size to other snake species?

King Cobras are among the longest venomous snakes in the world, but they are not the heaviest or the thickest. Anacondas and pythons, for example, can weigh more and have a bulkier body shape, but they are not as long as King Cobras.
