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?

Tigers are forced into unnatural situations in which they must share or remain in certain areas in a man-made environment; this is when they are referred to as an ambush or streak; even a Tigress with her cubs is referred to as an ambush.

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.

Mother hens teach their chicks not to ingest potentially harmful grains, where to obtain food, and how to forage. Chickens also mimic one other's actions; as chicken keepers are well aware, they will all do it if you can get one chicken to do anything you want.

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?

Dogs' ears, in addition to being able to move in a variety of ways, can hear considerably higher frequency noises than human ears. In fact, dogs can hear noises that are twice as far away as we can—and it looks that tiny dogs are even better at it. This is due to the fact that the smaller a mammal's head is, the more frequencies it can take up and compare in each ear. That is how they (and us) determine the source of noises.

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.

A female peacock's crest contains special sensors that allow her to detect vibrations from a distant mate. According to The Atlantic, the feathers are "tuned to vibrate at the same frequencies as a displaying peacock rattles his tail," according to The Atlantic. When a male peacock fans his tail, he shakes it 26 times per second, creating a pressure wave that rattles the female's head in a bid for attention.

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?

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?

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.

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?

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!

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.

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.

Earthworms each has both male and female sex organs, yet they are incapable of self-fertilization. Earthworms spend most of their life underground, where they build intricate burrow networks. They contribute significantly to soil fertility and so play a vital role in gardens and farmland.

Cheetahs, unlike most other large cats, hunt throughout the day. They scale a termite mound or a tiny hill, using their keen vision to identify prey, and then they're off to the races. The cheetah utilizes its fast speed to chase down its victim, knocking it to the ground and grabbing it onto its throat. Cheetahs have characteristic black tear-mark lines that go from the corners of their eyes down to the corners of their lips. These scars reflect the light, allowing the cats to hunt during the day. According to the Cheetah Conservation Fund, without the glare of the sun, they can focus on their prey.

Colored honey can be produced by bees. A biogas plant in France manages waste from a Mars chocolate factory, where M&Ms are manufactured. Beekeepers in the area noticed that their bees were producing honey with "unnatural shades of green and blue." According to a British Beekeepers' Association spokesperson, the coloured honey was caused by bees eating the sugary M&M waste.

To begin, you must first determine the location of an earthworm's front end. The saddle or clitellum, a fleshy ring around its middle that sits closer to its head-end, is the best method to determine. The common earthworm may survive having its tail cut off below the saddle because you'll be missing most of its major organs. Still, it'll never be the same again. So, if at all feasible, use caution when holding your lawn spade.

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.

Bandhavgarh National Park, also known as the 'Land of the Tigers,' has the highest density of Royal Bengal tigers in the world, as well as some of the most exotic wildlife that is difficult to see in other parts of India. There's a saying in the park that goes, "In any other park, you're lucky if you see a tiger; in Bandhavgarh, you're unlucky if you don't see (at least) one."

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.

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.

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.

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.
