You probably already knew that Royal Bengal Tigers are the largest of the wild cats, but did you know that male Tigers can weigh up to 300 kilograms? Jeez! That's the equivalent of weighing a group of six average humans. All they have to do is sit on top of you and lick their paws, and you're dead.

You might think that only fish have gills, but several species of sea snakes breathe through their skin as well. Hydrophis cyanocinctus, for example, has been discovered to breathe through the top of its own head. It has a small hole and a collection of blood vessels at the top of its head that picks up oxygen from the seawater and sends it to the reptile's brain as it moves underwater.

Crabs' claws may be able to frighten other species, but if that isn't enough, ghost crabs will snarl at their foes like a dog. Crabs, unlike our canine companions, generate these terrifying noises with fangs placed in their guts. They are part of the stomach's gastric mill machinery, where they rub against one other to grind up food.

Napoleon Bonaparte, the great conqueror, was once assaulted by...bunnies. The emperor had asked for a rabbit hunt for himself and his troops. His chief of staff organized it and had soldiers collect up 3,000 bunnies for the occasion. The hunt was set to begin after the rabbits were freed from their cages. That was the plan, at least! The rabbits, on the other hand, raced toward Bonaparte and his soldiers in a vicious and relentless onslaught. And we were told that Waterloo was the greatest defeat of the conqueror...

Every flock of sheep has its own hierarchy, and the ranking is determined by a sheep's gender and age. Leaders have superior positions at the feeder or when resting and can influence the behavior of other sheep. The process remains unchanged until shearing, when it sparks a mini-revolution. Along with their distinguishing traits, look, and scent, sheep, lose their position and must compete to determine who is worthy of being at the top.

There is a peafowl that is completely white. Captive peafowl frequently defies the iridescent trend for all white feathers, thanks to selective breeding. This is known as leucism, and it is caused by a genetic mutation that causes pigmentation loss. These peafowls are frequently mistaken for albino, but animals with leucism retain their normal eye color rather than having red eyes.

Polar bears are heavyweight, and in them, male polar bears weigh more than female polar bears. Male polar bears are twice the size of female polar bears and can weigh up to 800kg. In addition to this, male polar bears can measure up to 3 meters long and are the largest land carnivore globally.

Elephants, the largest land animals, consists of around 150,000 units of muscle units in their trunk. Trunks of the elephants are considered the most sensitive organ found in any mammal. Asian elephants have been found to pick up a peanut, shell it, blow the shell out and eat the nut. Moreover, Elephants use their trunks to suck the water, and a trunk can contain up to 8 liters of water. Isn't this amazing?

They don't have to be slaughtered just to get their feathers. Fortunately, peacocks shed their train every year after mating season, allowing the feathers to be collected and sold without harming the birds. A peacock's average lifespan in the wild is about 20 years. Their beautiful feathers are used for decoration as well as handicrafts.

The sounds made by a cheetah are not frightening. Cheetahs sound more like a house cat than a lion, which is noted for their fierce roar. They purr and meow. They also chirp and create churring noises. Listen to some of the Toronto Zoo's noisy cheetahs. Lions, tigers, leopards, and jaguars are the four roaring great cats. They can generate their threatening noises because their voice box has a ligament rather than the epihyal bone. Lower noises are produced as the ligament stretches. Cheetahs have a fixed voice box and vocal cords that are split. It permits them to purr but limits the noises they may produce, similar to "little cats."

Greyhound dogs and cheetahs have bus lines named after them, but house cats are just as fast: the typical running feline can reach speeds of up to 30 mph. In a school zone, that's enough to obtain a ticket.

Wildlife enthusiasts have captured the Australian species Lyrebirds, mimicking other birds and other creatures such as koalas and artificial noises like vehicle alarms and camera shutters.

Mongolia is home to the two-humped Bactrian camel. The Thousand Camel Festival is organised by a local non-governmental organisation dedicated to preserving and protecting the Bactrian camel population, which has been progressively dwindling for the previous twelve years. At the event, you'll be able to engage with the camels and learn about the nomadic lifestyle of camel herders firsthand.

Russian scientists disproved the ancient concept of two-color vision. The experiment, which involved detecting full and empty food bowls of various hues, revealed that our pets are just as adept as humans are at recognizing the colors blue and yellow. Dogs, contrary to common perception, do not perceive the world in black and white. They, on the other hand, can't tell the difference between green and red.

DNA or deoxyribonucleic acid of a species plays an important role in its identity. And in the case of polar bears, scientists have discovered a new innovative technique to find out the DNA of polar bears. They can get to know about the DNA of a polar bear by its footprint on the snow. Isn't this interesting?

We are well aware of the teeth of the sharks. Sharks have several rows of teeth & have the capability of losing and replacing the teeth so many times in their lifetime. Sharks, as predators play an important role in the health of marine ecosystems- by eating the fishes, sharks maintain the food chain.

Those who come into contact with a grizzly bear will undoubtedly want to keep out of reach of the animal's razor-sharp claws. They'll also want to stay clear of the grizzly's mouth since, according to National Geographic, these animals "have a bite-force of over 8,000,000 pascals." This indicates that grizzly bears can shatter a bowling ball between their teeth. Yikes!

Chickens (and all birds) are true dinosaurs since one lineage of dinosaurs survived the cataclysmic extinction 65 million years ago, the birds. Chickens descended from dinosaurs and are the closest surviving related to the mighty Tyrannosaurus rex. On the other hand, Chickens are the most prehistoric and 'dinosaur-like of all of our current birds. You can see a velociraptor just by watching them run and some of the sounds they make (I'm looking at you, broody hen).

Cheetahs are carnivores that eat tiny animals that they can readily hunt and kill. According to the San Diego Zoo, this contains smaller antelopes such as Thomson's gazelles and springboks, as well as rabbits, porcupines, and ground-dwelling birds. They consume the meat rapidly before more aggressive predators such as leopards, lions, baboons, jackals, and hyenas arrive and compel them to give it up. Vultures can even chase them away. Cheetahs are swift, but they aren't powerful or aggressive enough to pull their prey a long-distance or protect it from these ferocious competitors. Cheetahs only require water every three to four days.

Like humans and other mammals, Chickens go through a REM (rapid eye movement) phase of sleep, which is associated with dreaming. However, they have another sleep phase that humans do not, known as USWS, in which one half of the brain sleeps while the other half is awake. Chickens can sleep with one eye open, an evolutionary adaptation that allows them to watch for predators as they sleep.

For those who are allergic to cats, be aware that they may also be allergic to you! It's unusual since we bathe more frequently than other species and don't lose as much hair or dead skin, but it does happen.

Yes, cockroaches are quite fast. Have you ever tried to catch a roach? If not, try it out to see how fast they are. They can move quickly up walls, across slick surfaces, and so on.

Male seahorses are the ones who become pregnant and give birth to their progeny. A male seahorse may give birth to anywhere from one to two thousand fry at a time. A single pregnancy lasts roughly two to four weeks. When the fry are ready to be born, the male seahorse contracts his muscles in order to eject the progeny from its pouch.

Do you believe that immortality is a pipe dream? It is, after all, for people. However, scientists have discovered that the Turritopsis dohrnii jellyfish may revert to its juvenile polyp stage after maturing, allowing it to continue in an unending cycle, making it the only officially immortal organism. Do you enjoy mind-blowing facts?

Only the males are referred to as "peacocks." "Peafowl" is the collective term for these birds. The males are known as "peacocks," while the females are known as "peahens." The babies are known as "peachicks," but peacocks are more commonly known for their beautiful feathers and vibrant colors.
