Large groups of piranhas may gang up on an older, weaker anaconda near the end of its life. Caimans, which are smaller members of the alligator family may also prey on smaller or weaker anacondas, although, when the anaconda is full grown, it is known to prey on the caiman.
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 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.
Green anacondas are one of the largest snakes in the world. Reports of anaconda attacks on humans are rare, but these boas can take down large prey, including jaguars.
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.
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.
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.
The tiger has an advantage earlier but is soon overtaken by the giant anaconda.
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.
#1: Snakes
One might think a giant snake such as a reticulated python or anaconda would be likely to defeat an elephant, but that's not true. Neither of them has the strength to kill elephants.
Green anacondas are the heaviest snakes in the world. The heaviest anaconda ever recorded was 227 kilograms. This massive snake was 8.43 metres long, with a girth of 1.11 metres.
No, because piranhas don't eat crocodilians. They eat seeds, fallen leaves, scales, small fish, and carrion.
The grizzly wins every time. It can kill an anaconda with one bite anywhere on the middle of the body and it's claws can rip the snake apart in a matter of seconds. The anaconda would have a tough time just wrapping itself around the huge bear.
The decidedly not-extinct anaconda can swallow five-foot long Caiman crocodiles, but those gargantuan snakes can reach 20 feet long and 330 pounds, per Live Science.
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.
The snake is faster than you are. Don't try to outrun it.
Pantanal jaguars have been previously documented preying on anacondas, though bigger mammals like capybara, cattle, feral pigs, peccaries or giant anteaters (and caimans, of course) are more typical fare.
Predators. Leopards and crocodiles are large carnivores which may prey upon gorillas. Humans are the greatest threat to all gorilla populations.
Chimpanzees are not strong enough to rip limbs off, neither are gorillas. They cannot grapple as well as humans either despite having a lower center of gravity, because they simply don't train to grapple. Gorillas weigh 300350 pounds, but the strongest strongmen weigh 425500 pounds.
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.
What Eats It? Adults are top predators but juvenile dragons are preyed upon by adult dragons, feral dogs, wild boars, civet cats and snakes. Komodo dragons are solitary animal except during breeding although groups of dragons may gather to feed at a kill.
Komodo dragons are heavier than king cobras and they live in fewer places. Komodo dragons are monitor lizards and king cobras are snakes. The biggest differences between a Komodo dragon and a king cobra are morphological ones such as the Komodo dragon having legs to crawl with instead of slithering.
A crocodile would win a fight against a Komodo dragon. Crocodiles are simply too large and too powerful for a Komodo dragon to fight back against. One likely outcome would be the crocodile waiting for the Komodo dragon in the water and dragging it beneath the waves to suffer a brutal death.
