The adult anaconda does not generally have any predators since they are at the top of the food chain, being such a huge snake. However, the babies have predators that adult anacondas don't have, including birds and even jaguars.
Threats. At the top of the food chain, adult anacondas have no natural predators. The biggest threat to their survival is human fear; many anacondas are killed by people worried that the enormous snake will attack. They are also hunted for their skin, which is turned into leather or used as decoration.
the black piranha has the strongest bite force recorded for bony fish. number four tigers jaguars which are lighter than tigers have been reported to kill anacondas. so a tiger could likely do so as well the weight of a tiger can be even heavier than that of an anaconda.
Their eyes and nostrils are on top of their head, so they can keep their body hidden underwater as they wait for prey. Surprisingly, humans are the anaconda's most dangerous predator. In many parts of South America, anacondas are hunted, both legally and illegally, for their skin and for sale in the illegal pet trade.
Even in the cases of a large anaconda, a gorilla is so powerful that it would probably crush the anaconda's skull and end the threat before the anaconda could completely wrap around it. Gorillas are fast and ferocious in combat, so it's hard for a snake to take them by surprise and meaningfully attack them.
An anaconda would win in a fight against a python. These two creatures are so similar in every facet except for length, thickness, and weight, and those are the ones we have to use to determine who would win if they faced off.
The saw-scaled viper, Echis carinatus, is considered the deadliest snake in the world, according to Britannica. This type of snake is said to be responsible for "more human deaths than all other snake species combined." The venom of the saw-scaled viper is not as lethal as other snakes, but it is far more aggressive.
As carnivores, anacondas eat birds, deer, caimans, jaguars, and rodents.
A crocodile would beat an anaconda in a fight. A fully grown crocodile is simply too big and strong for an anaconda to kill. Even in an ambush situation, the anaconda would struggle to wrap enough of its body around the crocodile to inhibit its movement and crush it.
An adult anaconda would win a fight against a Komodo dragon. The Komodo dragon is a highly capable fighter, but it would not be able to deal fatal damage to the anaconda before it was grabbed and crushed. Anacondas can successfully attack crocodiles, creatures that can kill faster than a Komodo dragon.
Diet. The green anaconda will eat anything it can catch and overpower including rats, fish, birds, tapirs, capybaras, deer, warthogs, caimans, other snakes and reptiles, and even crocodiles. It is possible that on several occasions in the last decades that anacondas have even taken live humans.
The largest anaconda was reportedly 33 feet long, 3 feet across at its widest part, and weighed about 880 lbs. This snake was discovered at a construction site in Brazil. Unfortunately, it either died in the controlled explosion after which they found the snake or by construction workers after it emerged.
In the wild, green anacondas are not particularly aggressive. In Venezuela, they are captured easily during the day by herpetologists who, in small groups, merely walk up to the snakes and carry them off.
Anacondas will always suffocate their prey to death first before swallowing it, since it would be dangerous to have a live deer or tapir kicking in the stomach. Even when their prey is dead, swallowing something this large is quite risky for these snakes and they can sometimes die in the attempt.
Introducing the most venomous snake in the world and epic predator of the Australian outback! The inland taipan is otherwise known as the fierce snake or small scaled snake.
Some fun facts about the Black Mamba:
They are some of the world's fastest snakes and are capable of speeds of more than 12 miles (19 km) per hour and hence will be the one which can kill the fastest. In the wild, a black mamba can live for up to 11 years.
Anacondas are a source of many myths that exaggerate their size and attacks on humans. Substantiated reports of giant constrictors actually killing and eating humans are quite rare.
Reticulated Python
Reticulated pythons are considered to be the longest snake. The world record for the length of a reticulated python is a whopping 32 ft and 9 ½ inches! Like the green anaconda, they are also excellent swimmers. Scientists have even found these incredible animals out at sea.
An anaconda would win a fight against a king cobra. This outcome assumes that both of these creatures met in an open area that doesn't allow an ambush to happen. Otherwise, the anaconda might just snatch the water-loving king cobra into the water and make for a much less interesting fight.
Predators. Asiatic wild dogs called dholes may prey upon tigers but these rare attacks are usually countered with drastic losses to the dholes' pack. Humans are the greatest threat to all tiger populations.
Deadly Squeeze. If the anaconda can wrap around the lion, its deadly squeeze could be enough to win this battle. As members of the boa constrictor family, anacondas don't need to use venom to kill their prey.
Their land movement speed tends to max out at 10 MPH, meaning grizzlies move nearly three times as fast. That might not relate perfectly to their actual combat speed, but it's still clear that the bear is bigger, faster, stronger, and way more equipped to do immediately lethal damage to the anaconda's body.
