mountain gorillas like other primates and humans are scared of water and some insects like caterpillars and reptiles like Chameleon. Gorillas like other apes including humans find it hard to swim naturally which prompts them to desist from expanse water masses (big water bodies) like Lakes and Rivers.
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.
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.
Predators. Leopards and crocodiles are large carnivores which may prey upon gorillas. Humans are the greatest threat to all gorilla populations.
HUNTING AND TRADE
The commercial trade in bushmeat, which occurs throughout west and central Africa, is the biggest threat to gorillas today.
In the wild their only predators are leopards, which can attack vulnerable youngsters and the biggest threat to gorillas is man. In recent decades gorilla populations have been affected by habitat loss, disease and poaching.
Though they are often portrayed as dangerous and aggressive, the truth is that gorillas are gentle giants. They are shy and retiring by nature, and usually only become aggressive when they feel threatened.
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. The most dangerous animal for the gorilla is unfortunately the human.
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. Yet, even if this fight turned into a pack war between several creatures, lions would still come out on top because they have far larger groups.
Gorillas show their signs of anger by throwing vegetation, making loud hoots, thumping the ground, beating their chests loud, moving on two legs and so much more.
Also, the gorilla is naturally very shy creatures. Like shy humans, staring directly into the eyes of gorilla make them feel uncomfortable and insecure and when disrupted by your direct eye contact, they can charge aggressively at you to defend themselves.
You will be advised to scream or shout loud and thump your chest just like the charged gorilla and the shouting will scare away the gorilla and also show that you are another wild gorilla.
Gorillas may cry out as vocalizations, but they actually don't produce tears like humans do when we cry. Gorillas produce tears in order to lubricate their eyes, but tear production as a form of distress is completely unique to humans within the primate species!
Like the other apes and humans, gorillas cannot swim naturally, therefore they avoid large bodies of water and rivers. However, in zoos and sometimes even in the wild, young and adult animals like to play with water.
While some may be excited to find the reptile, the majority of people would react in fear and confusion. Apparently gorillas have the same feelings about snakes.
A tiger would kill a gorilla in a fight. If a tiger managed to ambush a gorilla, the tiger would immediately kill it. Although the gorilla is strong, the fact is that it could not stop 600 pounds of charging muscle and teeth.
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.
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.
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.
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).
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.
When gorillas beat their chests they show how big their body is, assess the fighting ability of rivals and attract mates, according to new research. The sounds the beating makes may also allow individual gorillas to be identified across dense forests, researchers in Germany have found.
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.
