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. The one advantage that a Silverback might have is in the enormous strength of its muscles.
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 gorilla and grizzly have a relatively similar bite strength, but the bear's build makes it harder for a gorilla's bite to be equally as effective. The gorilla's biggest advantage is its spry movement, whereas the grizzly's primary advantage is its claws. The grizzly is larger, but the gorilla is stronger.
A gorilla can lift a weight 10 times of its body. This is about 2,000kg. A black bear can lift about 800 lb or less than 400 kg.
How hard can a gorilla punch? It is believed that a gorilla punch is strong enough to shatter your skull with one slam of its arm:/Between 1300 to 2700 pounds of force. Gorillas on (avg. 400 lbs) have a muscle mass density almost 4 times higher than the most heavily muscled powerful human you know.
A lion would almost certainly win in a fight against a gorilla. The reasoning should not be all that surprising. A lion will stalk and ambush a gorilla in the dense vegetation of their natural habitat by waiting until it's dark to have the edge. They have a good chance at ending the fight in seconds.
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.
A hippo would win a fight against a polar bear.
Instead, the hippo needs one or two bites to incapacitate the polar bear. Its massive teeth would penetrate the bear's fur and skin, breaking bones and ripping into organs. In this rare case, speed on land would only matter at the beginning of the fight.
Forceful Hunter: Tigers
A tiger's bite can exert approximately 1,000 pounds of force per square inch. The tiger is one of the largest carnivores in the world, eclipsed only by the polar and grizzly bears. The most intimidating species, the Siberian tiger, can potentially weigh up to 800 pounds.
The neck is too thick to choke or snap. With smaller adversaries a gorilla could pick them up, smash them around, and even rip off a limb with its strength.
The black bear would win without difficulty due to the gorilla lacking physical features that the black bear sports, such as sharp claws.
A fully grown saltwater crocodile would win a fight against the largest bears. Size matters in these fights and crocodiles have that advantage. Bears are undoubtedly strong, but they've never faced anything like a crocodile to know their weaknesses.
A rhino would win a fight against a grizzly bear.
Grizzly bears are tough animals. They're also far more aggressive than the average solitary rhino. In a fight to the death, though, the rhino would clearly recognize that the grizzly is a threat that needs to be frightened off or eliminated.
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.
Dale McFadden. At the 1959 Great Stoneboro Fair in Pennsylvania, teenager Dale McFadden (weighing in at all of 115 lbs.) got in a cage with a 130-lb. gorilla.
With two such powerful creatures, we can't help but wonder what would happen if these two animals got into a fight. Unfortunately, a gorilla vs tiger fight cannot happen in real life unless they escaped their enclosures at a zoo!
No, an unarmed human being could not beat a gorilla in a fight. Simply put, gorillas are far too strong for human beings to overcome. If the human sees the gorilla first, the best the human could hope for is finding a nearby place to hide.
Highly unlikely, if no firearms or tranquilizer guns are involved. A gorilla can reach speeds of 20 mph to 25 mph. In comparison, Usain Bolt's record in the 100-meter dash roughly translates into 23 mph (Bolt reaches peak speeds of around 27 mph—but still).
But the most common statistic that I can find states a gorilla's strength at 10 times their body weight. If we take an average weight of a 400 lb (181 kg) for an adult male mountain gorilla, that means that it could hypothetically lift upwards of 4,000 lb (1,810 kg)!
Gorillas are stronger than you and me combined. The silverbacks are in fact stronger than 20 adult humans combined as they can lift or throw up to 815 kgs while a well-trained man can only lift up to 400 kgs. Any adult gorilla can lift up to 450 kilograms, not with a body size that can go as high as 200kgs.
Bear cubs often fall prey to tigers, wolves, cougars, and coyotes. Tigers, wolves, cougars, bobcats, coyotes, and humans eat bears, but these predators only focus on bear cubs rather than adult bears. The adult bears are too aggressive and dangerous to prey on – obviously a reason they are at the top of the food chain.
