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.
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.
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.
These animals have been described in the Guinness Book of Records as the "most fearless animal in the world" A pair of honey badgers take on a pride of lions. It is not for nothing that the honey badger has earned the reputation of being the most fearless animal in the world.
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.
Butterflies are not even able to defend themselves. The worst they can do is make one of their predators feel ill after it eats a butterfly. Conservationists have stressed that healthy moth and butterfly populations are essential to most ecosystems.
Jellyfish, starfish, and even corals manage very well without hearts. Starfish do not even have blood, so this explains why no heart is required. Instead, they use small hair-like structures called cilia to push seawater through their bodies and they extract oxygen from the water.
No rest for the Bullfrog. The bullfrog was chosen as an animal that doesn't sleep because when tested for responsiveness by being shocked, it had the same reaction whether awake or resting.
The 'immortal' jellyfish, Turritopsis dohrnii
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.
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
Koalas have the smallest brains of any known mammals, and their behavior can be compared to someone who is high.
The few that could definitely defeat us every time are tigers, brown bears, large sharks and the very massive herbivores like elephants, water buffalo and rhinos. Originally Answered: What is the largest animal that a average human could fight and come out on top?
Lions have famously acquired the title of 'King of the Jungle'.
Tiger – The Strongest Paw Swipe of All Big Cats
What is this? When battling with their prey, those large cats can even exert up to 10,000 pounds of force when swiping with their paws. On top of that, the average bite strength of a tiger is 1,050 PSI. Tigers can weigh between 220 and 660 pounds.
Scientists say that in a fight between a Bengal tiger and an African lion, there is a 90 per cent chance that the tiger will win. A tiger is slightly faster than a lion, arguably more ferocious, and more agile. A tiger is also 5 per cent taller and 8 per cent heavier than a lion.
Bengal tiger
The cats have razor-sharp canines, which can measure nearly four inches in length, and a strong bite force of 1,050 psi. Once trapped in a tiger's powerful jaws, it's nearly impossible for smaller animals to escape.
koala. Koalas are known for their laziness and sleeping abilities, spending only two to six hours awake every day. Their diet is to blame for their sleepiness though.
While mammals and birds possess the prerequisite neural architecture for phenomenal consciousness, it is concluded that fish lack these essential characteristics and hence do not feel pain.
