We often get fascinated by the horn of rhinos. But have you ever thought that of what stuff these horns are made up of? Actually, the horn of Rhino is made up of the same protein as our fingernails, i.e., Keratin. And the horn of rhinos grows with the time and continue to grow for the whole of their life. The horn of a white horned rhino grows about 7 cm in a year, and there is a record of 150cm longhorn of a rhino. Isn't this interesting?

Cats are genetically programmed to be unable to taste sweets. They will most likely nibble on your platter if it contains meat, but they will ignore it if it includes dessert.

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?

Their mothers would wrap them in kelp while hunting until the buoyant pups learn to paddle about independently. A swarm of otters will also clasp hands while sleeping to avoid drifting apart!

We, human beings, are generally aware of the 5 senses that we all possess. But have you ever thought about sharks? Sharks have a sixth sense too. The sharks' sixth sense helps them hone in ok prey during the final phase of an attack. On shark's snouts, the ampullae of Lorenzini is found that can sense the electric field emitted by the other animals in the water.

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.

Sharks can be found in all the temperate and tropical oceans except the Mediterranean Sea. And the whale sharks used to migrate thousands of miles to different feeding grounds. But they move very slowly, around 3 miles per hour.

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.

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.

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.

The most heartbreaking aspect is that tiger cubs are born blind, with only a few surviving. The newborn cubs can't see anything and can only follow their mother's scent. Because they are born blind and unable to keep up, the majority of them die of hunger or cold. Some are even devoured by male Tigers to make the Tigress available for mating. That is completely insane!

Everyone who has backyard chickens can verify that their birds recognize them and each member of their family. They can also recognize various animals, such as your dogs and cats. Chickens remember places and various members of their flock, even if they haven't seen them in months.

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.

Tigers, on the other hand, have antiseptic saliva, so if you get a bruise and want to disinfect it, go to the doctor Tiger, just kidding! Typically, they will lick the affected area to prevent infection.

Although there are around 25 billion chickens in the world today, more traditional or "heritage" breeds are increasingly in danger of becoming extinct. This is because industrialized chicken farming (and now factory farming) bred in attributes to improve meat and egg output while paying little attention to retaining the original breed features. It's notfunfun' fact, but it's vital to know.

This is one of the most fascinating facts about Eagles that we've discovered. The Bible considers these mighty creatures to be a manifestation of kindness and divine power. It is said that having confidence in God allows you to fly like an eagle. Eagles are frequently seen on state flags because they signify courage and independence, as well as incredible power and ability.

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?

Have you ever wondered or thought why snakes may make you feel uneasy? They don't even have eyelids! As a result, they cannot blink their eyes, and they sleep with their eyes wide open. To protect their eyes, they have a thin membrane linked to each of them instead of eyelids. The membrane is known as a brille, which translates as spectacles in German.

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.

Have you ever thought about how Rhinos communicate? They communicate through honks, sneezes, and poo. During confrontations, Rhinos snort when they are angry, sneezes when there is an alarming sign, screams when scared, and wink when relaxed. It has also been found that rhinos communicate through their urine and poo. The rhinos can smell the urine and poo, and this is the way they recognize each other. This is funny, right?

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).

This scientist grabbed a young monkey and began raising it with his 10-month-old kid. It outperformed the boy in all academic tests but was unable to learn to talk. The experiment had to be halted because the scientist's kid began to emulate the chimp's conduct. He made monkey noises when he wanted to eat or drink instead of learning a language.

They have existed since the time of the dinosaurs and may even be older than the dinosaurs. Cockroaches are found all throughout the world, and there are thousands of different species. All cockroach species can evolve in a variety of environments.

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.

They don't have fancy tail feathers because they're born with them. Male peachicks do not begin to grow their showy trains until they are about three years old. In fact, because peachicks are nearly identical to their mothers, it's difficult to tell their sex. The males will begin to change color to their vibrant blue around the age of six months.
