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.

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.

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!

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.

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.

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.

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.

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.

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.

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.

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?

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.

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.

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.

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.

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?

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.

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.

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.

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."

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 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.

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.

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.
