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.

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.

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.

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."

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?

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.

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...

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.

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.

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.

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."

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.

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.

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).

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.

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.

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.

Mongolia is home to the two-humped Bactrian camel. The Thousand Camel Festival is organised by a local non-governmental organisation dedicated to preserving and protecting the Bactrian camel population, which has been progressively dwindling for the previous twelve years. At the event, you'll be able to engage with the camels and learn about the nomadic lifestyle of camel herders firsthand.

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.

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.

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.

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?

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.

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.
