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?

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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...

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.

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.

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.

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.

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.

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.

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!

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?

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.

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.

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.

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.
