In 1937, a specimen shot in Guyana was claimed to have measured 5.9 m (19 ft 4 in) long and weighed 163 kg (359 lb 6 oz). Jesús Antonio Rivas, who had examined more than 1,000 anacondas, was a female 5.21 m (17 ft 1 in) long and weighing 97.5 kg (214 lb 15 oz). The longest and heaviest verified specimen encountered by Dr. Reports of anacondas 11–12 m (35–40 ft) or even longer also exist, but such claims must be regarded with caution, as no specimens of such lengths have ever been deposited in a museum and hard evidence is lacking. Although it is slightly shorter than the reticulated python, it is far bulkier the bulk of a 5.2-metre (17 ft 1 in) green anaconda is comparable to that of a 7.4-metre (24 ft 3 in) reticulated python. It is the largest snake native to the Americas.

Weights are less well studied, though reportedly range from 30 to 80 kg (66 to 176 lb) in a typical adult. More typical mature specimens reportedly can range up to 5 m (16 ft 5 in), with adult females, with a mean length of about 4.6 m (15 ft 1 in), being generally much larger than the males, which average around 3 m (9 ft 10 in).

The green anaconda is the world's heaviest and one of the world's longest snakes, reaching a length of up to 5.21 m (17 ft 1 in) long. The green anaconda's specific name is derived from the Latin murinus, meaning 'of mice', for being thought to prey on mice.ĭescription New England Aquarium Etymology įurther information on etymology of generic name: Eunectes § Etymology Fossils of the snake date back to the Late Pleistocene in the Gruta do Urso locality. The term " anaconda" often refers to this species, though the term could also apply to other members of the genus Eunectes. Like all boas, it is a non-venomous constrictor. It is the largest, heaviest and the second longest (after the reticulated python) snake in the world. Senator Eduardo Suplicy said Mr Pereira should be honoured by the Brazilian Government for heroism.The green anaconda ( Eunectes murinus), also known as the giant emerald anaconda, common anaconda, or common water boa, is a boa species found in South America and the Caribbean island of Trinidad. "It was totally coiled around him while he was screaming that he was dying." "It was the most terrible scene that I've seen in my life," Mr Pereira said.

He killed it after a long struggle to free the boy, who needed 21 stitches on his chest where the snake bit him. "I kept hitting it with the machete but it felt like a rubber tire, it wouldn't tear," he said. Mr Pereira then attacked it with stones and a machete.

"I started fighting the animal and tried to loosen its grip on the boy's neck but the snake was too strong," Mr Pereira told the Bom Dia newspaper of Sao Jose do Rio Preto. Mr Pereira jumped into the ravine and grappled with the snake, which started coiling around him as well. Joaquim Pereira was driving home when he heard the screams of Matheus and his cousin Flavio, who ran to get help. "My grandfather is a hero - I was so afraid of dying." When the snake struck on Wednesday, Matheus, who lives in the the world's third largest metropolis of Sao Paulo, was playing with a cousin in a creek bed on his grandfather's farm 500 kilometres from the city in a town called Cosmorama. They kill prey by asphyxiation or drowning. A 66-year-old Brazilian man wrestled with a five-metre anaconda for nearly half-an-hour to free his grandson from the snake's crushing death grip, local media reported overnight.Įight-year-old Matheus Pereira de Araujo would likely be dead inside the belly of the 35 kilogram anaconda if his grandfather had not heard his screams for help, zoologists said.Īnacondas, the biggest snakes in the world, live in swamps and rivers.
