The Antarctic blue whale (Balaenoptera musculus ssp. Intermedia) is the biggest animal on the planet, weighing up to 400,000 pounds (approximately 33 elephants) and reaching up to 98 feet in length.
#9 Hippopotamus
After elephants and rhinoceros, the hippopotamus is the third-largest land mammal and the heaviest surviving land artiodactyl.
Weighing up to 23,000 pounds and reaching lengths of 24 feet, the African bush elephant is the second largest mammal in the world.
Biggest Elephant: African Elephant (7 Tons)
The largest land-dwelling mammal on earth, at seven tons, the African elephant is smaller than the blue whale for good reason: The buoyancy of water helps to counteract the blue whale's weight, and elephants are terrestrial.
Far bigger than any dinosaur, the blue whale is the largest known animal to have ever lived. An adult blue whale can grow to a massive 30m long and weigh more than 180,000kg - that's about the same as 40 elephants, 30 Tyrannosaurus Rex or 2,670 average-sized men.
Sheer Size
The Megalodon weighs in at upwards of 50-70 tons, measuring a span of up to 60-70 feet in length. By contrast, the Blue Whale tips the scale at around 100-110 tons and tops lengths of up to 100 feet. Who Wins on Size? It's pretty obvious that the Blue Whale is the bigger apex predator in this fight.
Which animal can you beat in a fight? The weakest animal you could beat in a fight is a rat or cat (around 70%) while the strongest animal you could beat is a grizzly bear, lion, elephant, or gorilla (around 3%). The other animals include goose, dog, eagle, chimpanzee, cobra, kangaroo, wolf, and crocodile.
Unsurprisingly it's an elephant that is the heaviest land animal in the world - but which type and how much does it weigh? The African elephant is the heaviest land mammal on Earth, weighing up to 6.6 tonnes. Several adaptations enable the elephant to carry this bulk.
The blue whale is the biggest living being alive today and it is far larger than any megalodon. The blue whale can grow upwards of 100 feet long and weighs more than 110 tons. Simply put, this is an absolutely massive mammal that has no equal.
What are vampire bats? Bats are the only mammals that can fly, but vampire bats have an even more interesting distinction—they are the only mammals that feed entirely on blood.
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.
Fun Facts. The sperm whale has the biggest brain of any animal species, weighing up to 20 pounds (7 to 9 kilograms).
The animal that has 3 hearts is Octopus. Octopuses have two hearts to pump blood through the gills (breathing organs, like lungs, to breathe under the water) and a systemic heart that pumps blood to the whole body.
The Spinosaurus, the biggest land predator of all time, had a mouth similar to a crocodile's, and it had straight teeth like knives. The title of largest land predator that ever walked on Earth goes to the Spinosaurus. This meat-eating dinosaur lived about 90-100 million years ago.
The sperm whale is technically the loudest animal in the world, but the answer is up for debate because how we perceive loudness is subjective. Do you measure the loudest animal by the decibels they register or by the impact of the sound itself? The dispute comes down to two animals: the blue whale and the sperm whale.
The great bustard is probably the heaviest living animal that can fly. The males normally weigh between 10 and 16 kilograms, but some can reach 21 kg. For comparison, the wandering albatross has a larger wingspan, but only the biggest reach even 16 kg.
The Antarctic blue whale (Balaenoptera musculus ssp. Intermedia) is the biggest animal on the planet, weighing up to 400,000 pounds (approximately 33 elephants) and reaching up to 98 feet in length.
The Etruscan shrew (Suncus etruscus), also known as the Etruscan pygmy shrew or the white-toothed pygmy shrew, is the smallest known extant mammal by mass, weighing only about 1.8 g (0.063 oz) on average.
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.
Honey Badger – Fights Off Large Predators
A honey badger (Mellivora capensis) makes the list of toughest animals because it doesn't back down when approached by a predator – even if it's a lion or a leopard! A honey badger is about three feet long and weighs between 13 and 30 pounds.
Ungainly as it is, the hippopotamus is the world's deadliest large land mammal, killing an estimated 500 people per year in Africa. Hippos are aggressive creatures, and they have very sharp teeth. And you would not want to get stuck under one; at up to 2,750kg they can crush a human to death.
As ice formed at the poles and the sea level dropped, these pupping grounds would have been destroyed. A study from 2022 suggests that competition with great white sharks for food may also have contributed to megalodon's downfall. Studies of fossilised megalodon and great white teeth show that their diets overlapped.
With a stomach volume of almost 10,000 litres, the results suggest that the megalodon was capable of eating prey up to 8 meters long – whole! This means that today's top ocean predator, the killer whale, could have been eaten whole by this ancient sea monster.
Megalodons are extinct. They died out about 3.5 million years ago. And scientists know this because, once again, they looked at the teeth. All sharks – including megalodons – produce and ultimately lose tens of thousands of teeth throughout their lives.
