It's amazing for your kids about baby giraffe facts

It's amazing for your kids about baby giraffe facts.Check out some factoflife in my post.
Fun information and facts about giraffe for kids
Fact #1
The giraffe is the tallest mammal on earth. New-born baby giraffes are even taller than mosthumans. And males can grow up to 5.5 meters (18 feet) tall.
Fact #2
The neck of a giraffes is too short to reach the ground. So it has to awkwardly spread its front legs or kneel to reach the ground for a drink of water.

Fact #3
Like snowflakes and human fingerprints, no two giraffes have the same spot pattern.
Fact #4
Baby Giraffes can stand within half an hour of being born. After only 10 hours, they can actually run alongside their family.

Fact #5
Giraffes only need 5 to 30 minutes of sleep in a 24-hour period.
Fact #6
Giraffes only need to drink once every few days. Most of their water comes from plants they eat.
Fact #7
The idea that giraffes make no sound is untrue. When giraffes snort, bellow, hiss, etc, they make flute-like or low pitch noises beyond the range of human hearing.
Fact #8
Before mating, the female giraffe will first urinate in the male's mouth.

Fact #9
Giraffes are ruminants. This means that they have more than one stomach. In fact, giraffes have four stomachs, the extra stomachs assisting with digesting food.
Fact #10
Drinking is one of the most dangerous times for a giraffe. While it is getting a drink it cannot keep a look out for predators and is vulnerable to attack.
Fact #11
Male giraffes sometimes fight with their necks over female giraffes. This is called “necking”. The two giraffes stand side by side and one giraffe swings his head and neck, hitting his head against the other giraffe. Sometimes one giraffe is hit to the ground during a combat.
Fact #12
A giraffe's habitat is usually found in African savannas, grasslands or open woodlands.

Fact #13
The hair that makes up a giraffes tail is about 10 times thicker than the average strand of human hair.
Fact #14
Giraffes have a great sense of sight and smell and are able to run at speeds up to 35 miles per hour.

Fact #15
However, a baby giraffe in the wild is vulnerable because it has a shorter gait and is unable to keep up with the herd if a predator is detected. In the days and weeks following a birth, a mother giraffe will sometimes leave her baby hidden in tall grass for a few hours while she eats and roams.

Why our earth is round

Why our earth is round is an amazing question and everyone wants to find out the answer. Check out the below to get it


Take a walk outside to prove the point. Does it seem like you're walking on a giant, round ball? Do you feel yourself flying through the air around the Sun? No! Based upon your senses, would you guess that Earth is round? Does it seem like you're traveling around the Sun instead of the other way around? Wanna take a quick look at funny pictures with captions that can help you relax effectively.

Hundreds of years ago, people believed Earth was flat and that the Sun traveled around Earth. We now know different, but were those views really all that crazy back then? Probably not! The evolution of scientific knowledge has proven that, when it comes to astronomy, you can't always rely on your senses.

We already know that Earth is round. But why is it round? And is it perfectly round like a rubber ball? Let's see what science can tell us about the answers to those questions.

Two features of Earth that determine its shape are mass and gravity. These features are, in fact, interrelated. Mass attracts other mass, resulting in the force we call gravity. Smaller objects, such as a car or a house, have tiny gravitational forces. The amount of mass throughout Earth, however, is huge and really adds up, from amazingsciencefactsforkids

Scientists theorize that about 4.6 billion years ago, the solar system was a cloud of dust and gas. As gravity pulled the matter in on itself, it began to spin and clump up, forming the sun, planets, moons, and other space objects. Earth's rocky core was the first part of our planet to form, with dense matter sinking to the center and binding together. Then lighter pieces gathered and formed Earth's crust.

As Earth's mass added up from all this matter and gravitational forces increased, the matter attempted to take the most efficient shape possible: a sphere. If Earth was a cube, its corners would be farther away from its center than other points. Because gravityacts equally on everything, the corners would need to be pulled closer to the center. Check out my list of fun, weird and just plain amazing fact of life I have found.

The result of evening out the uneven places is that you end up with a shape in which every point on the surface is the same distance from the center. The only shape that fits that definition is the sphere. So, gravity is the answer to why Earth is round!

If you've seen pictures of asteroids that exist in outer space, you may have noticed that some of them are irregular, rocky shapes. That's because they're not big enough to pull themselves into a sphere. If they continue to grow and gain mass, eventually they, too, will form themselves into a sphere. Astronomers have made that ability — the ability to form into a sphere — as one of the requirements to be considered a planet!

If you've seen pictures of Earth from space, Earth does indeed look like a perfectly-round ball. Astronauts have even nicknamed it the “Blue Marble." Scientists will tell you, however, that Earth is not perfectly round. Its true shape is closer to that of an ellipsoid.

Image result for why our earth is round

Earth's constant rotation creates centrifugal forces that make Earth wider at the equator than the poles. How much wider? About 70,000 feet wider! You've probably also noticed that Earth's surfaceisn't flat. High mountain ranges and deep ocean trenches also contribute to Earth's slightly-irregular shape.

Earth's shape is also not static. It's always changing. Sometimes these changes are regular, such as daily tides that affect the oceans and Earth's crust. Other changes are irregular and extremely slow, such as the movement of Earth's tectonic plates. Sometimes natural disasters can result in sudden changes, such as is the case with earthquakes, volcanic eruptions, and meteor strikes. That might be one of the most awesome interesting facts ever.

There's actually a field of science dedicated to measuring and monitoring Earth's size and shape. It's called geodesy, and scientists with the National Geodetic Survey keep an eye on Earth's ever-changing shape and size.

Some of the most amazing Meerkat facts

Right here in this article, you can learn about all your favourite animals, and even some you may have never heard of some of the most amazing Meerkat facts


1. THEY RECOGNIZE EACH OTHER’S VOICES


Just as humans can identify our friends’ and family’s voices over the phone, a 2011 study showed that meerkats can distinguish between the calls of different members of their clan. Scientists played a recording of the same meerkat from hidden speakers on opposite sides of test animals. According to WIRED, "The situation was similar to hearing a friend shout from the kitchen, then from the second-floor bathroom just a second later." Indicating that they recognized this as an impossible situation, the test meerkats showed “a prolonged vigilance, paying much closer attention than they did to other recorded calls. The situation didn’t compute.”

2. THEY WORK TOGETHER ...

Meerkat clans, also known as mobs and gangs, hunt together in a collaborative effort that involves designated lookouts who rotate regularly and rely on a series of distinct calls to communicate to their compatriots. If a predator like a snake is detected, the gang will gather to harass the snake, biting and clawing at it until it retreats or is killed—a bold move one meerkat could never attempt alone.
Enjoy our wide range of funny pictures with captions that can make a joyful day.

3. ... AND EVEN BABYSIT EACH OTHER’S PUPS.



While most of the gang is out foraging and hunting for food—or standing guard—one male or female, adolescent or young adult stays behind in the burrow to “babysit” any pups. This is not an official job—whichever adult is least hungry is put on pup-sitting duty—but the other meerkats do reward their sitter with food at the end of the day.

4. THEY TEACH THEIR YOUNG.

Adult meerkats are immune to scorpion poison—a good thing when you regularly make treats out of the stinging arthropods. But it takes talent to tuck into that sort of prey—even with their poison nullified, a scorpion can still do damage with his pinchers—and pups aren’t born prepared for such a vicious meal. Research done in 2006 showed that “helper” meerkats actively teach the younger generation how to hunt through a series of increasingly difficult tasks. "So when pups are very little they get brought dead prey, like scorpions, lizards, and spiders; as they start to get older, helpers will bring them prey that's been disabled, so if it's a scorpion the helper might bite the sting off before giving it to the pup,” scientist Alex Thornton told the BBC.

5. GANGS ARE MATRIARCHAL.

Meerkat gangs, which can reach up to 40 or 50 animals, are structured around an alpha couple to whom most of the other members are somehow related. Within the dominant pair, ultimately it is the female who rules the burrow, and she isn’t always a benevolent boss. Only the alpha female is allowed to reproduce; if subordinate females get pregnant, the alpha female will banish them from the burrow or even kill their pups. Research conducted in 2013found that some subordinate females will serve as wet nurses to alpha female pups in order to re-ingratiate themselves after getting banished. Anyway, this may be one of the most fascinating animal facts until now

6. MATRIARCHS ARE REALLY REALLY SELFISH


As if infanticide and exile weren’t bad enough, alpha females only have their own interests at heart. A 2013 study showed that when a gang of meerkats approaches a road—which represents an unknown and potential danger—alpha females tend to suddenly fall back, letting lower ranking females brave the pavement first.

7. THEY USE THEIR BELLIES TO KEEP WARM.

Meerkats' fuzzy tan coats give way to a sparsely covered patch on their underbellies [PDF]. The hair is thin enough there that you can see their black skin underneath—which is precisely the point. After a restful night in the chilly burrow, meerkats climb back out into the desert sun and stand up to expose to their bare bellies to the rays, which absorb heat and warm the animals up.

8. THE FORKED-TAIL DRONGO MIMICS MEERKAT CALLS.

The African drongo scavenges for food by tricking other animals into abandoning their hard-earned meals with carefully crafted calls that imitate the warning sounds of other species. So after a gang of meerkats has made their kill or foraged sufficient food, the drongo will descend among them and mimic the same warning call a meerkat sentry might make in the event of a predator. The gang scatters, and the drongo gets a free meal.

Open your mind with Jaguarondi facts

Open your mind with Jaguarondi facts

Jaguarondi (jaguarundi) is a species of wild cat that resembles large otter in appearance. Because of that, it is also known as otter cat. Jaguarondi lives in Southern parts of North America, Mexico and South America. 


There are 8 subspecies of jaguarondi that can be found in wide variety of habitats: tropical rainforests, savannas, semi-arid areas, woodlands and swamps. Number of jaguarondis in the wild is decreased for several reasons. Farmers kill jaguarondis because they hunt and feed on their poultry. Jaguarondis often end up trapped in the nets set for other animals. Finally, habitat loss greatly reduces number of jaguarondis in the wild. Despite all this, jaguarondis are not listed as endangered species.
  1. The jaguarundi is a very unusual cat that is often described as having a weasel-like appearance. It has a long slender body, short legs and a small flattened head with short rounded ears, the cat is often described as.
  2. Sometimes referred to as the ‘otter-cat’, the jaguarundi is closely related to the puma.
  3. One of the smaller New World cat species, they are about twice the size of a small house cat. Jaguarundis are unusual as they do not have spots, unlike most other South American small cats. This might be one of the most amazing facts about animals ever seen
  4. Jaguarundis are very elusive animals and there is still a lot to be learnt about them.
  5. Population numbers of the jaguarundi are much less than once thought. They live in very low densities and their shy nature makes it difficult to estimate their population size. Overall the population is in decline due to habitat loss to agriculture.
  6. They have some of the most variable colourations of wildcats, with two main groups: a dark morph which includes cats with black, brownish and grey colours, and a paler red morph ranging from tawny yellow to a bright chestnut red.
  7. For many years, it was thought the two morphs were separate species but it is now known that both colours can occur from the same litter.
  8. Generally, it seems the darker morph is more common in rainforest habitats and the paler morph in drier environments.
  9. Unlike most other cat species, the jaguarundi tends to be most active during daytime rather than dawn or dusk.
  10. Jaguarundis are very vocal cats, with at least 13 distinct calls that include chirps, purrs, whistles and even a scream.
  11. Choosing to spend more time on the ground than many other big cat species, the jaguarundi tends to hunt small mammals, birds and reptiles on the ground. They have also been witnessed to jump as high as two metres off the ground to swipe a bird from the air!
  12. Jaguarundis have very large home ranges. Some males were recorded as having a range from 88 to 100km2! Females tend to have much smaller ranges – varying from 13 to 20km2.
  13. The Texan population of jaguarundis may now only consist of a few remaining cats. Habitat loss has caused this population decline. Let’s discover some interesting science facts that will amaze you.
  14. In parts of North America there have been some reintroduction efforts but these are hindered by the lack of scientific knowledge about the animal, its needs and behaviours.
  15. The breeding behaviour is not well known; scientists are unsure whether jaguarundis raise cubs alone or as a pair. Females will have between 1-4 young which remain in the den for around 28 days.
  16. The jaguarundi are not hunted for their fur like many other cats but they will often be caught in traps set for other animals such as the ocelot.

List of fun, weird and just plain amazing black-footed ferret facts

List of fun, weird and just plain  interesting facts about black-footed ferret and information are right here


Once thought to be globally extinct, black-footed ferrets are making a comeback. For the last thirty years, concerted efforts from many state and federal agencies, zoos, Native American tribes, conservation organizations and private landowners have given black-footed ferrets a second chance for survival. Today, recovery efforts have helped restore the black-footed ferret population to nearly 300 animals across North America. Although great strides have been made to recover the black-footed ferret, habitat loss and disease remain key threats to this highly endangered species.



Black-footed ferret facts

  1. The endangered black-footed ferret is a member of the weasil family. It is the only ferret native to North America.
  2. It is roughly the size of a mink, and differs from the European polecat by the greater contrast between its dark limbs and pale body and the shorter length of its black tail-tip.
  3. These solitary animals live alone, and in May and June females give birth to litters of one to six kits that they raise alone.
  4. Kits are born blind and helpless and stay below ground until they are about 2 months old. At this age, the female begins to take her young on hunting forays and separates the kits into different burrows. Let’s discover some interesting science facts that will amaze you.
  5. Black-footed ferrets are nocturnal and primarily hunt for sleeping prairie dogs in their burrows.
  6. They are most active above ground from dusk to midnight and 4 a.m. to mid-morning. Above ground activity is greatest during late summer and early autumn when juveniles become independent.
  7. Climate generally does not limit black-footed ferret activity, but it may remain inactive inside burrows for up to 6 days at a time during winter.
  8. Up to 91% of the ferret's diet is composed of prairie dogs which are essential to their survival, though they will sometimes eat squirrels, mice and other rodents.
  9. A ferret may eat more than 100 prairie dogs in one year.
  10. Black-footed ferrets once numbered in the tens of thousands, but widespread destruction of their habitat and exotic diseases in the 1900s brought them to the brink of extinction. Only 18 remained in 1986.
  11. The animals were once found on black-tailed prairie dog colonies across the Great Plains from southern Canada to northern Mexico, and on white-tailed and Gunnison’s prairie dog colonies across the intermountain west. By 1986, they were completely gone from the wild.
  12. Today, they have been reintroduced to 15 locations within their former range in Wyoming, South Dakota, Montana, Arizona, Colorado, Utah, Kansas and Chihuahua, Mexico.
  13. Ferret reintroduction efforts have been mixed. Populations need viable prairie dog towns to survive, but they also face threats from predators such as golden eagles, owls, and coyotes. Reintroduced animals lack some survival skills so their mortality rate is high.
Are you bored? Let’s have a quick look at our funny images that are bound to bring smile on your face.

How can monkeys protect themself

Wondering how monkeys protect themself? This fun facts will be answered in this today article as below. Enjoy!

Monkeys always live in groups that have a distinct hierarchy, and it is the responsibility of the leaders of these groups to organize the other monkeys to defend against predators. When fighting with each other, monkeys may bite or scratch.
I know for sure that many of us have a keen interested on interesting science facts about everylife aspects that are shown in our site.

When threatened by ground-based predators such as hyenas and jackals, adult monkeys gather together to bark, bare their teeth and possibly throw sticks or other debris in an attempt to scare them off. If this does not work, the monkeys may attack the predator as a group. Some monkeys, such as capuchins, can use sticks as clubs. Monkeys that live in trees have little defense against airborne predators such as eagles and simply attempt to hide from and avoid them.

Some types of male monkeys may fight among themselves for dominance in the hierarchy and to display their abilities to females. They may exhibit any of the techniques they use against predators when fighting amongst themselves. Monkeys have also sometimes been used in fights against other types of animals, a practice known as monkey-baiting. Records of some of these fights indicate that an adult male monkey was consistently able to defeat dogs by leaping onto their backs and clawing and biting at their windpipes.
