There is a surprising number of animals that have little or no fear of humans. Some of them come by that lack of fear naturally. For instance, grizzly bears and American bison are local animals that tend to be unafraid of people. Neither has much to fear, either, since both are easily a match for an unarmed human.
The most famous example is that of the dodo, which owed its extinction in a large part to a lack of fear of humans, and many species of penguin (which, although wary of sea predators, have no real land predators and therefore are very bold and curious towards humans).
The honey badger is not afraid of anything.
Panda Bears
These fluffy black and white bears are one of the most adorable mammals. For the most part, pandas are pretty easy going and just eat bamboo most of the day, however, if they feel threatened they can be extremely dangerous. They can use their physical strength, strong jaws, and teeth to do a lot of damage.
Most lions flee, even from people on foot, but an attack is a possibility and knowing how to react could save your life. Walking safaris are a relatively new concept, and lions still perceive humans on foot as a threat.
Like many large carnivores, wolves are generally afraid of humans and will avoid people, buildings, and roads if possible. The risk of wolves attacking or killing people is low. As with other wildlife, it is best not to feed wolves and to keep them at a respectful distance.
Nevertheless, attacks in human villages do occur. Most tigers will only attack a human if they cannot physically satisfy their needs otherwise. Tigers are typically wary of humans and usually show no preference for human meat. Although humans are relatively easy prey, they are not a desired source of food.
The quokka, a small marsupial native to Australia, is one such example of a species vulnerable to extinction in the country's harsh surroundings. Known as the “happiest animal in the world” due to its cute and friendly appearance, these creatures are now only found in a few isolated forests and small islands.
Wolves generally avoid human interactions, unless they have become habituated to people. Please do your part to keep wolves the way they belong—wild. Keep your distance from wolves. Remain at least 100 yards away when watching or photographing them.
“Those are situations where a strike might happen.” Both venomous and nonvenomous snakes are extremely wary of humans and are not prone to strike. A bite is their last-ditch effort to avoid harm. Simply leaving a snake to do its job in the landscape is the best way to avoid a bad encounter.
Generally, spiders want to avoid humans and will only bite as a defense mechanism if they are provoked. Many are extraordinary at hiding or camouflaging themselves because they don't want to be seen.
Bears are normally wary of people, but if a bear finds food without getting frightened away, he may come back for more. Each time this happens, he can become less fearful—and this habituation can lead to problems.
Lions are extremely accomplished predators and adept hunters. For them, humans count as prey. Ignoring their prowess in this department is a big mistake.
If you encounter a wolf or pack of wolves at close range do not run or turn away. If you are approached, act aggressively and maintain eye contact if the wolf is looking at you. Aggressively use poles, pepper spray, rocks, limbs, noisemakers or other handy items to discourage wolves.
No, an unarmed human could not beat a lion in a fight.
Even if a human came upon a sleeping lion, their chances of killing it would be laughably small. Humans aren't going to knock out a lion with a kick or punch in one shot. They're also not going to strangle a lion to death.
African elephants can distinguish human languages, genders and ages associated with danger. Humans are among the very few animals that constitute a threat to elephants.
"Lions are wary of crocodiles and will generally avoid the water to stay away from crocs," writes NatGeo TV.
Mantis shrimp pack the strongest punch of any creature in the animal kingdom. Their club-like appendages accelerate faster than a bullet out of a gun and just one strike can knock the arm off a crab or break through a snail shell. These small but mighty crustaceans have been known to take on octopus and win.
1. American Pit Bull Terrier. The American Pit Bull Terrier is considered one of the most dangerous dog breeds – both in the U.S. and internationally. They are a very aggressive breed and have been known to attack and kill people.
The strongest land animal in the world is the elephant. The typical Asian elephant has 100,000 muscles and tendons arranged along the length of the trunk, enabling it to lift almost 800 pounds. The gorilla, the strongest as well as largest primate on the planet, is at least six times stronger than the average human.
