The question what is the biggest snake can be confusing, the biggest as far as girth (largest being measured at 44 inches or 1,1176 m) is the Green Anaconda, on average anacondas are more then 20 ft (6.09 m) long with and average weight of 300+ pounds (136.08+ kg) many reaching lengths of 29ft ( 8.83 m) or more, with a weight of over 550 lbs ( 249.48 kg), in terms of length then and only then will the Reticulated Python exceed the anaconda, the longest python was measured at 33 ft ( 10.05 m) but even this python can't match the total mass of the anaconda.
Anacondas are members of the Boidae family of reptiles and spend most of their time in rivers and swamps of the Amazon Rainforest in South America which makes them excellent swimmers and are capable of holding their breath for around 15 minutes, female anacondas are generally 3 to 4 times larger then the males and bear their young live and are called "Neonates", the number of young varies, some have produced 100 babies, but the average is between 20 to 40 babies which are about 24 inches (0.6 m) long, they stay with the mother for about and hour then leave to be on their own. Diet consist of (depending on the size of the anaconda, the larger the snake the larger the prey) large/small rodents like capybaras, also pigs, caiman, jaguars, deer, dogs, birds even fish and is acquired by ambushing with a quick strike, 100 rear-facing sharp teethhold the prey while suffocating it with constriction, (the anaconda is so powerful it generally crushes it's prey) then swallowing it whole and by using it's muscles in a rhythmic fashion it works the food toward its digestive area, the digestion of the anaconda is very slow thereby allowing it to survive without food for well over a year.
Anacondas have around a 10 to 12 year year life span in the wild, in captivity some have reached 20 + years, the biggest threat to it is man and loss of their habitat.
By its thickness,length, and strength used to wolf down large prey.
They are constrictors and predators.
No, it restricts they prey to death. It has many little teeth to hold the prey in it's jaws while it eats it. Being a water based snake though it can develop a bacteria in it that will makes wounds heal slower.
Anacondas are deadly
nope, it's a constrictor
No
Green anacondas are recorded to attack and kill/wound people in water and on land.
Yes. They squeeze the life out of their prey.
jaguars, other anacondas, and humans.
Yes. Humans can and have killed anacondas.
Anacondas are aquatic snakes and examples include the green anaconda. Their prey is aquatic animals like fish. They rarely prey on humans, because anacondas live in swampy environments where people rarely visit, and an encounter between it and the human being is very dangerous.
Since Anacondas are at the top of the food chain in their habitat, the only real threat comes from humans in their efforts to use anacondas skin for profit. This may range from shoes to other man made accessories at the expense of this creature. Anacondas are also hunted and killed because humans fear them.
Pirahnas, jaguars, hippos, crocodiles, humans.
Because humans are destroying the snakes naturalhabitat !
They weigh the weight of a bus around a humans neck
The anaconda puts the squeeze on you.
yes they can
Anacondas always hunt only when hungry. They can eat any animal they can manage to capture. Young Anacondas prefer prey such as fish, frogs, rodents etc. Adult Anacondas can overpower many different kinds of prey. They can eat turtles, sheep, dogs, jaguars, bird eggs, smaller sized mammals etc. Contrary to what is shown in the movies, Anacondas do not really attack humans unless it's provoked. Reports do not reveal a large number of attacks on humans. Therefore, you can probably be rest assured Anacondas are not particularly on the hunt for humans for their daily meals!
