The native to the Amazon rainforest of South America, green anacondas are the heaviest snakes in the world, weighing in at about 249 kg (548 lbs) and measuring about 6 meters (12 feet) long. They are powerful constrictors, with stocky muscles that are much thicker than those of any other snake in the world. It’s vital for me to stress the following point, by the way:
Since the beginning of the Amazon’s discovery, especially in the late 19th and early 20th centuries, there have been several stories claiming to have seen enormous huge anacondas that can reach lengths of up to 40 feet (the equivalent of 12 meters long)! For instance, renowned British explorer Percy Fawcett claimed to have seen and killed a 62 ft (18 m) long anaconda during his first expedition in the jungle in 1906, a claim for which he was scorned by scientists. English naturalists Henry Walter Bates and Alfred Russel Wallace also implied to have witnessed anacondas beyond 30-40 ft (9-12 m), not to mention that these tales accuse the snakes of being habitual man.
According to one theory, some anacondas’ sizes tend to be exaggerated when people encounter other large animals that are not as enormous as they seem, such as bears, crocodiles, giraffes, sharks, elephants, squids, whales, etc. Since primates have spent millions of years coexisting with large snakes, humans have evolved to have hyperactive snake-detecting circuits in their brains. As a result, a person may mistaken.
