#1 Dogs. Fiercely loyal and affectionate, dogs are the most popular animals and considered man's best friend.
Dung Beetle
A dung beetle is not only the world's strongest insect but also the strongest animal on the planet compared to body weight. They can pull 1,141 times their own body weight. This is the equivalent of an average person pulling six double-decker buses full of people. Now that's strong!
After elephants and white rhinos, hippos are the third-largest living land animal.
Mosquitos are by far the deadliest creature in the world when it comes to annual human deaths, causing around one million deaths per year, compared to 100,000 deaths from snakes and 250 from lions. Perhaps surpringly, dogs are the third deadliest animal to humans.
#1 Blue Whale
Strictly speaking, the largest mammal ever on Earth doesn't walk, it swims, but no biggest animal list would be complete without the massive Blue Whale, considered the largest animal to ever live, as well as the heaviest animal ever known to exist.
Strongest Kick: Zebra – Kicks with About 3,000 Pounds of Force. Between the well-known force behind the kick of a red kangaroo and a giraffe, you might be surprised to read that the zebra beats them both. When threatened, an adult zebra can kill a fully grown male African lion with a single blow to the body.
In terms of muscular strength, tigers are stronger. Lions live in Africa and India. Lions are the second largest of the five big cats in the genus panthera.
And the strongest known bite force of the entire animal kingdom is…. The Crocodile -- specifically, the Saltwater Crocodile (the highest recorded “live” bite of 3700 PSI) and the Nile Crocodile (estimated 4000-5000 PSI)!
1: Chimpanzee
Chimpanzees can learn sign language to communicate with humans. Topping our list of smartest animals is another great ape, the chimpanzee. The impressive intellectual abilities of this animal have long fascinated humans.
Dolphins are often cited as the second smartest animals on Earth due to their relatively high brain-to-body size ratio, the capacity to show emotion, and impressive mimicry of the dumb apes who research them.
According to the BBC Science Focus, the smallest animal in the world is the Etruscan shrew. The Etruscan shrew, also known as the white-toothed pygmy shrew or Suncus etruscus, is located in North America.
Although tigers are at the top of the food chain and do not have a direct predator, they may be afraid of some animals. They commonly feel threatened by lions, bears, elephants, rhinos, hyenas, hippos, crocodiles and buffalo.
Key Points. Elephants and rhinos are the animals most likely to kill lions. The humble porcupine is a threat to mighty lions. A crocodile is an animal that will attempt to prey on lions.
“What eats me”
Lions have few predators to fear other than humans. A very young or sickly lion might fall prey to hyenas. Cubs may be attacked and eaten by adult male lions. Lions are most threatened by humans who hunt them and encroach on their habitat.
Blue whale calves are the largest animal babies in the world, clocking in at a whopping 1360kg —almost the same size as a small car.
Blue Whale
Not only is the blue whale the most massive animal on earth, but it's also one of the fattest. Though this marine mammal typically has about 35% body fat, it can get up to a whopping 50% in times of plenty.
Cheetahs are the world's fastest land animal, capable of reaching speeds of up to 70 mph.
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.
