Ostriches have a wingspan of up to 6.6 feet despite not being able to fly. Rather than aiding in flight, these appendages assist birds in maintaining their balance while running or defending themselves against predators. They can also function as rudders, allowing the ostriches to change directions while running. Finally, wings aid ostriches in their courtship displays, which include chasing and dancing to assert dominance over other potential mates.

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.

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?

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.

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?

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.

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.

Although the Incas brought llamas and alpacas to Machu Picchu, and tourists enjoy taking selfies with llamas today, neither species is native to this region of Peru. Llamas and alpacas prefer elevations of 13,000 feet (4,000 m) or higher. The llamas you see today at Machu Picchu—and even the grass they eat!—were brought in specifically for tourism purposes.

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.

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."

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.

Except for humans, these apes live in the jungle, as do all other great apes. The more vigorous the rainforest in that location, the healthier the gorilla population. They not only consume a large portion of its leaves, but their scat also serves as a highly rich fertilizer for the forest floor. Plantlife increases faster in locations where they live than in other areas.

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).

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."

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?

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.

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!

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!

Although it is not true that all Tigers are nocturnal, they do prefer to conduct the majority of their hunting activities at night. The reason for this is that Tigers prefer to avoid human conflict during the day and patrol their territory at night.

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!

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.

These creatures, renowned for their peaceful lifestyle, like going for a swim. Even though a sloth travels 2 meters per minute on land, it can travel 5 times quicker in the water! Because of their sluggish metabolic rate, animals can go for extended periods without breathing.

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.

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.

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.
