  • The Burmese python inhabits swamplands in Southeast Asia and China, where it is vulnerable due to habitat destruction, trapping and killing for skin and food.
  • The king cobra, which can grow up to 13 feet long, isn't the world's longest snake, but it's the world's longest venomous snake.

What is the largest snake in the world? What is the longest snake in the world? With more than 3,000 species of snakes living worldwide, there are many candidates to consider.

The largest snakes listed here were chosen because of their exceptional length.

Brown king snakes ( Pseudechis australis ) can grow up to 11 feet long. Although the snake was 11 feet long, it only weighed around 13 pounds. The brown king snake is not the largest snake in the world, but it is quite large.

This venomous snake lives in the grasslands, woods and bushes of central Australia. A mixture of yellow and brown scales helps camouflage it as it moves its long body in search of frogs and lizards. With a dwindling population, its conservation status is Least Concern.

The hood of the king cobra is actually a rib. They are known for their size, however, they use their voices to protect themselves in the wild. They have a very long lifespan compared to other snakes and their biggest predator is the mongoose.

The Burmese python ( Python bivitattus ) is one of the largest snakes in the world, reaching lengths of up to 23 feet and weighing up to 200 pounds. This reptile lives in the swamps of Southeast Asia, including China. Its body has a circumference, or thickness, equal to that of a pole! Like the other pythons on this list, the Burmese python wraps its strong body around its prey to suffocate it.

With a dwindling population, their conservation status is fragile. These snakes are captured and killed for their skin and used as food. Habitat destruction has also resulted in fewer prey for this snake, thus reducing its overall population.

Burmese pythons have become an invasive species in the Florida Everglades after escaping captivity as pets. Recently, the largest invasive Burmese python was caught in Florida. The female snake was 18 feet long and weighed 215 pounds. Although they can weigh as much as a person, they are not the largest snakes in the world.

The Southwest Florida Conservancy has been implanting radio transmitters in male scout snakes and releasing them into the wild to locate breeding colonies where large, fertile females can be found.

They're trying to drive the females out of the wild, hoping to slow their population growth.

#3. Amethyst Python – 27 feet long

other dangerous animals found in the world

Not only is the lion one of the largest big cats after the tiger, but it is also one of the most dangerous. Lions are the top predators of the African savannah and have no natural enemies, making them even more dangerous when defending their territory or their cubs from other predators. The king of the jungle is estimated to kill an average of 22 people a year in Tanzania alone. While deaths do occur elsewhere, global figures are not detailed.

The African buffalo is considered one of the most dangerous animals in Africa as they are known to lie in wait for their pursuers and then charge at them at the last moment. Hunters are wary of the large cattle of sub-Saharan Africa, of which there are five subspecies, including the most aggressive Cape buffalo. Cape buffalo are at the height of their attacks when the herd's calves are under attack.
