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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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?

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.

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."

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.

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.

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.

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.

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.

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.

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?

They don't have fancy tail feathers because they're born with them. Male peachicks do not begin to grow their showy trains until they are about three years old. In fact, because peachicks are nearly identical to their mothers, it's difficult to tell their sex. The males will begin to change color to their vibrant blue around the age of six months.

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.

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.
