The champion is without a doubt Elephant, the biggest being the African Bush Elephant. They are the largest land animal today and the strongest as well, no other land animal can fight an Elephant including Rhinos and Hippos.
It's a tardigrade—the most 'indestructible' animal on Earth. Also called water bears, tardigrades can survive up to 30 years without food, live in volcanoes, and endure the vacuum of space. Researchers say they could even survive an asteroid impact like the one that led to the extinction of the dinosaurs.
Despite its size, the manta ray (Cephalopterus manta) fits on our list of harmless animals. Unlike the stingray, it does not attack other animals or humans. In some countries, it was once common for divers and swimmers to catch rides on these gentle giants. They usually live in tropical waters and feed on smaller fish.
The honey badger has been called the world's most fearless animal because it doesn't hesitate to attack animals much larger than itself- even lions and crocodiles! Honey badgers are found in arid grasslands and savannahs and even rainforests.
Rats and house cats were the easiest presumed pushovers, with two-thirds of participants claiming they could see one off, while grizzly bears, elephants and lions were rightfully respected – only 2 per cent of pollsters claimed they would be able to take one down.
Tardigrades are among the most resilient animals known, with individual species able to survive extreme conditions – such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation – that would quickly kill most other known forms of life.
Animals with no natural predators are called apex predators, because they sit at the top (or apex) of the food chain. The list is indefinite, but it includes lions, grizzly bears, crocodiles, giant constrictor snakes, wolves, sharks, electric eels, giant jellyfish, killer whales, polar bears, and arguably, humans.
It's important to note: Tardigrades are basically indestructible only when they enter a special state called cryptobiosis. In harsh environments, the animals tuck in their legs and expel all moisture from their bodies. In this state, they're called tuns.
To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
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.
Soon, we learned of the many myths surrounding the number of stomachs in the average Etruscan Shrew. Some believe the species evolved 800 stomachs, though it's difficult to imagine.
Almost every living creature on the planet has at least the strength to support its own body and move around. One exception to this is the jellyfish that is one of the weakest animals. Have you ever seen a jellyfish washed up on the beach? Its body or bell becomes flattened with no water to support it.
Lions have famously acquired the title of 'King of the Jungle'.
Four species of sharks account for the vast majority of fatal attacks on humans: the bull shark, tiger shark, oceanic whitetip shark and the great white shark.
Hippopotamus (Hippopotamus amphibius)
Causing an estimated 500 deaths annually (as compared to only 22 for lions), hippos are deadly land mammals. This is because they are very aggressive and territorial, and have a habit of charging at boats and capsizing them.
While larger animals like sharks or hippos may seem a likely culprit, the animal that kills the most humans per year is actually the mosquito.
A kangaroo would win a fight against a human being.
Do not be fooled by videos of humans successfully attacking a kangaroo. In the wild, a kangaroo will try to grasp their prey and then tear into it with the claws on its feet. This will inflict devastating wounds on a human being or even disembowel them.
Gorillas sometimes hit each other with sticks or rocks. It is normal for gorillas to fight lions – or any other predator – if they feel threatened. They also sometimes hit each other with sticks or rocks. So, yes, it is normal for gorillas to fight lions – or any other predator – if they feel threatened.
An unarmed human could not beat a wolf in a fight.
Wolves are too strong, fast, and ferocious for a person to overcome in the vast majority of cases. They are not merely big dogs. Wolves are apex predators that would make any lone person recoil in fear should they encounter one in the wild.
