10 Longest Snakes in the World

1.  Reticulated Python (Python reticulatus)

Python reticulatus, also known as the (Asiatic) reticulated python, is a species of python found in Southeast Asia. Adults can grow to 6.95 m (22.8 ft) in length[4] but normally grow to an average of 3–6 m (10–20 ft). They are the world's longest snakes and longest reptile, but are not the most heavily built. Like all pythons, they are nonvenomous constrictors and normally not considered dangerous to humans. Although large specimens are powerful enough to kill an adult human, attacks are only occasionally reported.
An excellent swimmer, Python reticulatus has been reported far out at sea and has colonised many small islands within its range. The specific name, reticulatus, is Latin meaning "net-like", or reticulated, and is a reference to the complex color pattern.

2. Green Anaconda (Eunectes murinus)

Common names in Latin America, green anaconda, anaconda, common anaconda, water boa.
Eunectes murinus is a nonvenomous boa species found in South America. It is the heaviest known snake species. The term "anaconda" often refers to this species, though the term could also apply to other members of the genus Eunectes.
The green anaconda is one of the world's longest snakes, reaching more than 6.6 m (22 ft) long. It is the largest snake native to the Americas and probably the heaviest extant species of snake or squamate. Reports of anacondas 35–40 feet or even longer also exist, but such claims need to be regarded with caution, as no specimens of such lengths have ever been deposited in a museum and hard evidence is lacking. A $50,000 cash reward is offered for anyone who can catch an anaconda 30 ft (9.1 m) or longer, but the prize has not been claimed yet. Although the reticulated python is longer, the anaconda is the heaviest snake, with a 4.5m green anaconda having bulk comparable to a 7.4m reticulated python. The longest (and heaviest) scientifically verified specimen was a female measuring 521 cm (17.09 ft) long and weighing 97.5 kg (215 lb).

3. Indian Python (Python molurus)

Python molurus is a large nonvenomous python species found in many tropic and subtropic areas of Southern and Southeast Asia. It is known by the common names Indian python, black-tailed python and Indian rock python.
A large snake, generally reaching up to 6 metres and in extreme cases over 9 metres, the Indian Python P. m. molurus inhabits lowland forests. It is adept at both swimming and climbing trees. As with other pythons, it kills its prey - mainly small mammals- by constriction and suffocation.
The patterning comprises black-edged brown patches on a pale orange-brown to yellow-brown background. On top of the head is a distinctive lighter, forward-pointing, V-shaped marking. 
The Indian Python occurs in Pakistan, India, Bangladesh, Nepal and Sri Lanka. A related subspecies, the Burmese Python P. m. bivittatus, occurs in Burma, South China, Thailand and Indo-china with a separate distribution in parts of Indonesia.

4. Diamond Python (Morelia spilota)

Morelia spilota is a large snake of the Pythonidae family found in Australia, Indonesia and New Guinea. There are 6 subspecies listed by ITIS, commonly referred to as carpet pythons and diamond pythons.
Morelia spilota is a large species of python in the genus Morelia, reaching between 2 to 4 metres (6.6 to 13 ft) in length and weighing up to 15 kilograms (33 lb). M. s. mcdowelli is the largest subspecies, regularly attaining lengths of 2.7–3 m (8.9–9.8 ft).[4] M. s. variegata is the smallest subspecies, averaging 120–180 cm (3.9–5.9 ft) in length. The average adult length is roughly 2 metres (6.6 ft). However, one 3-year-old captive male M. s. mcdowelli, measured in Ireland, was found to exceed 396 cm (12.99 ft). Males are typically smaller than females; in some regions females are up to four times heavier. The head is triangular with a conspicuous row of thermoreceptive labial pits.
The colouring of Morelia spilota spilota is highly variable, olive to black with white or cream and gold markings. The patterning may be roughly diamond shaped or have intricate markings made up of light and dark bands on a background of gray or a version of brown.

5. King Cobra (Ophiophagus hannah)

The king cobra is the world's longest venomous snake, with a length up to 5.6 m (18.5 ft).[1] This species, which preys chiefly on other snakes, is found predominantly in forests from India through Southeast Asia to Indonesia and the Philippines. Despite the word "cobra" in its name, this snake is not a member of Naja ("true cobras") but belongs to its own genus. The king cobra is considered to be a very dangerous snake, capable to kill a elephant.

6. Boa Constrictor

The Boa constrictor is a large snake, although only modestly sized in comparison to other large snakes such as the reticulated python and Burmese python, and can reach lengths of anywhere from 3–13 feet (0.91–4.0 m) depending on the locality and the availability of suitable prey. There is clear sexual dimorphism seen in the species, with females generally being larger in both length and girth than males. As such, the average size of a mature female boa is between 7–10 feet (2.1–3.0 m), whilst it is 6–8 feet (1.8–2.4 m) for the males. It is common for female individuals to exceed 10 feet (3.0 m), particularly in captivity, where lengths of up to 12 feet (3.7 m) or even 14 feet (4.3 m) can be seen. A report of a Boa constrictor growing up to 18.5 feet (5.6 m) was later found to be a misidentified green anaconda.
The Boa constrictor is a heavy-bodied snake, and large specimens can weigh up to 27 kg (60 lb). Females, the larger sex, more commonly weigh 10 to 15 kg (22 to 33 lb). Some specimens of this species can reach or possibly exceed 45 kg (99 lb), although this is not usual.

7. Bushmaster (Lachesis)

Lachesis is a genus of venomous pitvipers found in remote forested areas of Central and South America. The generic name refers to one of the Three Fates in Greek mythology who determined the length of the thread of life. Three species are currently recognized.
Adults vary in length from 2 to 2.5 m (6.5 to 8.25 ft), although some may grow to as much as 3 m (10 ft). The largest known specimen was just under 3.65 m (12 ft), making it the longest venomous snake in the Western Hemisphere. This is also the longest viper in the world. Although they are not the heaviest vipers, being surpassed in mass by the gaboon viper and the Eastern diamondback rattlesnake, large adults still commonly weigh up to 3 to 5 kg (6.6 to 11 lb).[4] The bushmaster's tail ends with a horny spine which it sometimes vibrates when disturbed in a similar manner to rattlesnakes. This led to some calling it 'the mute rattlesnake.

8. Giant Brown Snake (Pseudonaja textilis)

The eastern brown snake , often referred to as the common brown snake, is a species of genus Pseudonaja. This snake is considered the second most venomous land snake based on its LD50 value (SC) in mice. It is native to Australia, Papua New Guinea and Indonesia.
This species has an average length of 1.1–1.8 m (3.6–5.9 ft). The maximum recorded size for the species is 2.4 m (7.9 ft), although any specimen of greater than 2 m (6.6 ft) in length would be considered exceptionally large. Large eastern brown snakes are often confused with "king brown" snakes (Pseudechis australis), whose habitat they share in many areas.

9. Diamondback Rattlesnake (Crotalus atrox)
Crotalus atrox USFWS.jpg
Is a venomous rattlesnake species found in the United States and Mexico. It is likely responsible for the majority of snakebite fatalities in northern Mexico and the second greatest number in the USA after C. adamanteus.
Adults commonly grow to 120 cm (3.9 ft) in length. Specimens over 150 cm (4.9 ft) are infrequently encountered, while those over 180 cm (5.9 ft) are very rare. The maximum reported length considered to be reliable is 213 cm (6.99 ft) (Klauber, 1972). Males become much larger than females, although this difference in size does not occur until after they have reached sexual maturity.[5] Rattlesnakes of this species considered medium-sized weighed 1.8 to 2.7 kg (4.0 to 6.0 lb), while very large specimens can reportedly weigh up to 6.7 kg (15 lb).

10. Indigo Snake (Drymarchon couperi)

The eastern indigo snake is a species of large nonvenomous colubrid snake native to the Eastern United States. It is of note as being the longest native snake species in the U.S.
The eastern indigo snake has an even blue-black coloration, with some specimens having a reddish-orange to tan color on the throat, cheeks, and chin. This snake received its name from the glossy iridescent blackish-purple sheen it displays in bright light. This smooth-scaled snake is considered to be the longest native snake species in the United States. The longest recorded specimen measured 2.8 m (9.2 ft). Unlike many snakes, mature male indigo snakes are slightly larger than females. A typical mature male measures 2.13–2.36 m (7.0–7.7 ft) and weighs 3.2–4.5 kg (7.1–9.9 lb), whereas a mature female typically measures around 2 m (6.6 ft) in length and weighs 1.8–2.7 kg (4.0–6.0 lb). In specimens over 2.6 m (8.5 ft), these snakes can weigh up to 5 kg (11 lb). Although the indigo snake is heavier on average, unusually large specimens of the co-occurring Eastern diamondback rattlesnake can outweigh them.
