1. Southern African Rock Python

This subspecies of the African rock python, typically measuring between 11 and 16.5 feet (3.5–4.2 meters), is a formidable presence in Southern Africa. Its adaptability makes it well-suited to the region's drier savannas, woodlands, and rocky terrains.

2. Yellow Anaconda

The yellow anaconda, found in the slow-moving rivers and wetlands of South America, generally reaches lengths of 10–13 feet (3–4 meters). While smaller than its green counterpart, with some individuals exceeding 15 feet (4.6 meters), it remains a powerful aquatic predator.

3. Boa Constrictor

Boa constrictors are widely distributed throughout tropical South and Central America. These snakes typically measure between 10 and 13 feet (3 to 4 meters), but some can grow up to 18 feet long. They are known for their docile nature and powerful physique, inhabiting both forests and semi-dry regions.

4. King Cobra

The king cobra, the world's longest venomous snake, can attain lengths of up to 18 feet (5.5 meters). Native to the forests of India and Southeast Asia, this species is revered for its intelligence, distinctive hood, and the potency of its venom, capable of killing with a single strike.

5. Green Anaconda

The green anaconda reigns as one of the largest snakes on the planet, residing in the rivers and wetlands of the Amazon Basin. It can reach an impressive length of 33 feet (10.6 meters) and weigh up to 227 kilograms, solidifying its position as the heavyweight champion of the snake world.

6. Reticulated Python

The reticulated python, indigenous to Southeast Asia, holds the record for being the longest snake species. These snakes commonly exceed 20 feet (6.09 meters) in length, with some specimens reaching nearly 33 feet (10 meters). Their slender build and intricate patterns contribute to their striking and intimidating appearance.

7. Amethystine Python (Scrub Python)

The amethystine python, also known as the scrub python, is found in Indonesia, Papua New Guinea, and northern Australia. While it can grow to lengths of 18-28 feet (8.5 meters), it is typically shorter. This non-venomous snake is named for the iridescent, amethyst-like sheen of its scales.

8. Burmese Python

This giant snake, typically measuring around 16–20 feet (5–5.8 meters) in length, inhabits the Southeast Asian region. Burmese pythons are found in forests and marshes and are recognized for their considerable size and relatively docile temperament. However, they have become an invasive species in certain areas of the United States.

9. African Rock Python

As Africa's largest snake, the African rock python can exceed 10-16 feet (6 meters) in length. Found throughout sub-Saharan Africa, it is a powerful and aggressive constrictor capable of hunting large prey, including antelopes. This makes it one of the strongest constrictors in the world.

10. Indian Python

Also known as the Indian rock python, this species can grow up to 20 feet (6 meters) long, although most individuals average around 13–16 feet. Inhabiting forests and swamps across the Indian subcontinent, the Indian python is a non-venomous snake known for its immense strength.
