Although a silverback gorilla is very fast, quite strong, and has a longer arm span, it is unlikely that a silverback could defeat the much larger and faster grizzly bear in a fair fight.
Being close to the bear means being close to the mouth full of gnashing teeth and at least five claws ready to tear the gorilla apart with one swipe. With the bear's massive body, superior muscle, surprising speed and evolutionary armory, there really isn't any way a gorilla wins the fight.
The only predator to prey on gorillas is the leopard. Walter Baumgärtel found the remains of several gorillas after they had been killed by leopards in the Virunga Volcanoes. Another case has been confirmed in Gabon, where a sick young gorilla was killed by a leopard.
They are both highly aggressive creatures, so a prolonged fight could be brutal. Even then, the lion would probably come out on top, making up for its relative lack of stamina with sheer power. A lion has a good chance of killing a gorilla in a one-on-one fight. The only thing is that a lion rarely fights alone.
Predators. Leopards and crocodiles are large carnivores which may prey upon gorillas. Humans are the greatest threat to all gorilla populations.
Certain reptiles such as chameleons and caterpillars are what are gorillas scared/afraid of. They are also afraid of water and will cross streams only if they can do so without getting wet, such as by crossing over fallen logs, and dislike rain.
individual leopards smaller than lions have killed gorillas on rare occasions hippos are also known to prey on animals larger than gorillas. they have also killed nile crocodiles which are over twice the size of a gorilla in addition to lions a hippopotamus can easily kill a gorilla.
For many humans to beat a mountain gorilla, that would need your strength combined into one person which is even impossible. Muscles aren't thick enough to prevent human from choking them out.
Would it surprise you to know that an adult bear has almost no predators? Bears are large and can be quite intimidating so they don't have many enemies. Their biggest enemies are humans and each other. It's the cubs and the smaller females that have to watch out.
On land, the bear could possibly win a fight if it managed to flip over a crocodile and attack its underside. However, this fight would not be over quickly: the bear would need to do a lot of damage to finally kill the reptile.
A bear would win a fight against a lion. Bears have the advantage in just about every aspect, from size to offensive capabilities. The only time that a lion would win is if it managed to sneak up and ambush a bear, leaping onto it and biting into its head with such power that it shattered the skill.
However, grizzly bears are tougher than polar bears as they possess stronger and longer claws and an elongated skull with sharp and long canines that can completely separate the flesh from bone.
Grizzly bears are known to be more aggressive than gorillas, but gorillas are incredibly intelligent and can use their problem-solving skills to outsmart their opponents. A gorilla may use its superior intelligence to avoid conflict altogether in a confrontation, while a grizzly bear may charge its opponents head-on.
In the battle of the grizzly bear vs tiger, a Siberian tiger would win a fight against a grizzly bear. The Siberian tiger is an ambush predator, and it's the only big cat that comes close to the grizzly bear in terms of size and power.
"T. rex has bone-crushing teeth, but nothing to grab with other than its head, which, of course, isn't of much use if a 10-ton gorilla has a hold of you." "Hands down, the 25-foot-tall gorilla wins," agrees J. ... The Spinosaurus would not have been able to kill a T-Rex, although it would be a tough fight ...
Exerts Most Absolute Force: Whales
A blue whale can generate a maximum force of approximately 60 kilonewtons. Whales can claim the title of the strongest creature on the planet simply due to their enormous size.
What animal can kill a gorilla? The gorilla's only natural predator is the leopard, and even they very rarely actively hunt juvenile gorillas. Crocodiles and anacondas share a habitat with them and can be deadly to gorillas, but these attacks only occur on rare occasions.
Like humans or other wild animals, gorillas do get aggressive. However, they do so only when they feel threatened or when a silverback from another group attempts to steal one of the females. Gorillas will first attempt to warn off an intruder by making loud grunts and tearing down vegetation.
Even if it appears that the gorilla means to harm you, do not actively resist or fight back: It will interpret this behavior as threatening and may attack more severely. If the gorilla has gotten hold of you, begin to “groom” its arm while loudly smacking your lips.
The average gorilla is approximately six to 15 times as strong (depending on who you ask). All those techniques that we rely on to defeat stronger opponents aren't going to be enough to overcome that much strength differential: You will not be arm-barring a gorilla, for instance, even if you're Rickson Gracie.
Polar Bear (Strongest Land-Based Carnivore)
Due to the Polar bear's superior size and strength, it is the world's largest and most powerful land carnivore. The polar bear would almost certainly kill the gorilla if the two ever met.
Certain reptiles such as chameleons and caterpillars are what are gorillas scared/afraid of. They are also afraid of water and will cross streams only if they can do so without getting wet, such as by crossing over fallen logs, and dislike rain.
