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.

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.

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!

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.

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.

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.

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.

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!

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?

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?

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.

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.

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.

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!

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.

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.

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.

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.

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."

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.

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.

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.

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."

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.
