Corrected entry: When the girl is strangled in the boat, after she is dead you can see her abdomen moving as she breathes.
Corrected entry: When a tree falls on the boat the posse is forced to get to land and fight the snake in the water. However, when they return to the boat in haste, the huge tree is gone and they continue down the river.
Correction: The tree actually frees the boat from being stuck. After the first snake is killed, Ice Cube says, "The tree knocked us loose."
Corrected entry: Adult snakes, even the size of the one that appeared in Anaconda, can't eat more than one large meal at a time before going into a torpor that lasts for 3-6 months. After the snake ate the first person the rest of the cast would've been in no danger. Also, if the snake kept on eating people, one after another, in real life it would likely die, its digestive system couldn't handle the sheer amount of food.
Correction: It's not the same anaconda throughout the whole movie.
Corrected entry: When the anaconda lunges for someone from the top of the waterfall, it quickly shoots down, grabs them, and easily lifts them up. In reality, if an anaconda was stupid enough to attempt this stunt, it would have just fallen off. They are sluggish and out of place out of the water, and could never move like the whiplike creature portrayed in the movie.
Correction: The snake was halfway wrapped around the tree when he grabbed Westridge and the combined weight of both Westridge and the snake is what caused the tree to fall.
Corrected entry: When the anaconda is behind the boat she shoots at it about 5 times with a bolt-action rifle, and never reloads.
Correction: Not all bolt action rifles are single shots. Many have magazines that hold extra bullets and the sliding of the bolt feeds them into the chamber.
Watching the movie right now, that bolt action doesn't have the clip, it must be reloaded every time.
Corrected entry: When the anaconda eats Jon Voight whole, there is a movement over the other side of the room, and it slides over at incredible speed. Snakes take hours to eat their prey (especially the size of a man) and weeks to digest. During this period, they can barely move at all. Also, after it spits him out (again, not possible), he winks.
Correction: Maybe it goes for regular sized anacondas but not giant huge anacondas that they have to take hours. Also it is possible to spit out their food. On Google theres a REAL video of an anaconda spitting out an entire baby hippo.
Hippos are native to Africa, and anacondas to South America. Also, snakes regurgitate their prey only in an emergency, like being threatened by a predator. Even gigantic anacondas like the ones in the movie would still take several weeks to digest a person, and remain immobile throughout.
They don't move intentionally, to help digesting their prey. That doesn't mean they can't actually move though, they can if they have to. This big one is faster than any real snake anyway. In the footage of an anaconda regurgitating its prey, the prey is a tapir.
Hippos can be found in the wild in South America. They were the pets of Pablo Escobar. A group of hippos originally imported by Escobar to his private zoo decades ago has multiplied and, according to scientists, is now spreading through one of the country's main waterways - the River Magdalena.
Correction: This is because she's unconscious, not dead. She dies after she's kicked into the water and drowns.
