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.

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.

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?

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.

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.

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).

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.

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."

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.

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.

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?

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?

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.

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.

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.

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.

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.

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?

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...

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."

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.

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!

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.
