Baby giraffes

The tallest land animal in the world - giraffes that have many amazing facts about their life and their baby giraffe. Let's see to know more about them.

The Life of the Giraffe

According to University of Michigan's Animal Diversity Web, female giraffes will not breed until they are at least 4 or 5 years old, while males might not breed until they are around 7 years of age. Young giraffes are vulnerable to predators, so females rely on each other to keep their babies safe.

Baby's Coming

There's no specific breeding season for giraffes, so births occur at different times throughout the year. Mom is pregnant for up to 465 days before the baby -- usually one, although twins are possible -- comes around. Once it is time for the delivery, Mom will step away from the herd so she can give birth alone.

Baby's Here

At the time of birth, babies can be as tall as 6.6 feet. That's a good thing, since Mom gives birth standing up -- and it would be a long way to the ground if the babies were much smaller. Babies will be up and walking within minutes, and they'll begin to suckle right away. The mother and baby will remain isolated for about a week before they join a larger group. During that first week, babies will remain rather quiet and hidden, according to Animal Diversity Web. Mom will step away for short periods of time during the first few weeks, but will return at night to protect and nurse the baby.

After a period of about two years, the mother feels safe leaving her young to enjoy life on their own. If the young giraffe is a female, she will head off on her own to find a group of females to spend much of her life with. If a male, he may do likewise, by finding a group of males to herd with until time comes for him to branch off and search the many groups of females for a mate.

What does the name Scotch whiskey mean?

Most of us know that scotch whiskey is from Scotland but it's not all. The name of this kind od wine includes some other amazing news that will make you surprise.

Scotland

The title of “Scotch” is defined and regulated by a document created on November 23, 2009 called the “Scotch Whisky Regulations 2009” or SWR. Not only regulating production, the act also governs the labeling, packaging and the advertising of Scotch whisky within the United Kingdom. The SWR is a complete replacement of the previous regulations which focused exclusively on the production process. While the SWR is technically only valid within its jurisdiction, international trade agreements have been put in place which effectively make some provisions of the SWR apply in countries outside the United Kingdom.

The document defines Scotch whisky in the following manner:

1. Must be produced at a distillery in Scotland from water and malted barley (to which only whole grains of other cereals may be added) all of which have been:
  •  Processed at that distillery into a mash
  • Converted at that distillery to a fermentable substrate only by endogenous enzyme systems
  • Fermented at that distillery only by adding yeast
  • Distilled at an alcoholic strength by volume of less than 94.8% (190 US proof)
  • Wholly matured in an excise warehouse in Scotland in oak casks of a capacity not exceeding 700 litres (185 US gal; 154 imp gal) for at least three years

2. Scotch whisky must retain the color, aroma and taste of the raw materials used in, and the method of, its production and maturation.

3. It may not contain any added substances, aside from water and plain (E150A) caramel coloring.

4. It must comprise a minimum alcoholic strength by volume of 40% (80 US proof).

Interesting information about tigers

Reading for more interesting information about tigers facts

1. Tigers Hunt By Ambush


A tiger prefers to attack by surprise, if the tiger knows he or she has been spotted it is very unlikely it will attack. In some places in India the locals wear masks with a head facing behind to prevent tiger attacks.

2. Tigers cannot purr.

You might think that because it’s simply a big cat a tiger would be able to purr, right? Well, that’s actually not the case. Instead of purring to show happiness, a tiger will actually squint its eyes or even close them completely. Since losing vision lowers the tigers defenses, it will only do this if it feels very comfortable and safe. Closing its eyes around you translates to “I feel very happy when you’re here, so much so that I can relax for a bit!”

3. Tigers have been known to imitate the call of other animals to successfully attract prey.

Bears and tigers will typically cross paths with each other since their habitats can overlap. It would make sense, then, that tigers have developed a taste for bears and bear food. In order to lure a bear directly, tigers have been known to imitate the sound of a bear’s prey. Once the bear is close enough (thinking its found a meal for itself) the tiger attacks.

4. Most tigers have yellow eyes, but white tigers usually have blue eyes

The gene for blue eyes is usually linked to the gene for white fur, so white tigers are much more likely to have blue eyes, rather than the typical yellow kind. In addition to the blue-eyed gene being linked, the gene for being cross-eyed, or boss-eyed, is also linked, so many white tigers have crossed blue eyes. Darn! Gorgeous blue eyes have to come with a price, I guess.

5. Tigers have spiked penises

Ouch. Just writing that sentence made me uncomfortable! Tigers are unable to become erect when aroused. Instead, males penises’ have a bone located inside (called a baculum) and are covered with barbs. Those prickly spikes aid in “keeping the connection” (no pun intended) between the male and female during copulation.

6. A backhand from a tiger can kill you

While tigers typically prefer to use their 10 cm long teeth to crush a victim’s jugular (lovely!), a single strike is enough to do some serious damage. One swipe from a tiger’s front paw is strong enough to smash a bear’s skull or even break its back. Tiger, please. 

7. Tigers can come in a variety of colors

Photo Credit: Tambako the Jaguar

Different hair color genes can cause a tiger to vary from its usual black and orange coloration. A tiger’s coat can be white, gold, black, and quite possibly even blue. While there have been reports of blue tigers, called Maltese Tigers, there have been no verified specimens with this unique coloration… though I have seen enough photoshopped pics to start believing there might have been.

7. A Tiger’s Stripes Are Also On Their Skin


If you shaved all the fur off a tiger you will still be able to see it’s stripes on the cat’s skin.

Bengal tigers and their awesome facts

Here are some amazing news and facts tigers for kids about Bengal tigers:

Kết quả hình ảnh cho tiger for kids

From head to tail, males can measure from two to three meters. The height of his withers (neck) is of 91 cm. The males weights about 250 kg. He can live up to 25 years. He lives in the south of the Sundarbans delta, the largest mangrove forest in the world, which lies in India, and spreads across areas of Bangladesh.

Bengal tigers can also be found in north and central India, as well as in Birmania and in Nepal.

In 1900, they were about 40.000 – 50.000. Around 1972, there remained 1.850. In 1984, thanks to a program of protection, they were numbered approximately 4.000.
Related to: elephant facts for kids

Tigers hunt at night. They assault their preys on the side or at the back. They bit to death at the nape of the neck small preys; they bit at the throat bigger preys and let them suffocate to death. The Bengal tiger hunts the “yaur” (kind of wild bull), the buffalo, the (wild) boar, monkeys and lizards. When hungry, a tiger can kill up to 30 buffaloes per annum. He can also eat 31 kg of meat within a night. It takes between 2 or 3 days for a tiger to eat its prey. Between two meals, he covers its prey with leaves.

The Bengal tiger usually breeds in the springtime. A male from a neighbouring field comes on the female's field. About 15 weeks later, the tigress brings between 2 and “babies” into the world, sightless during the first ten weeks. After eight weeks, the latter will be able to start eating the little preys brought by their mother. The tiger is a night hunter and lonesome. He does not like sharing his territory with other tigers. Tigers mark their territory by urinating and secreting which smell strongly and indicate their presence. They can also savage to pieces the bark of a tree. He can run up to 45 km per hour.

A tiger print can measure 13 cm of diameter that is to say the equivalent to your two hands placed side by side. A forefoot has five fingers, and a hind foot has four fingers. Thanks to the cushions under his feet, the tiger can approach a prey without making any noise and absorb the choc of his gigantic leaps.

During the warm hours of the day, the tiger stays in one of his cool hiding places. His strong smell is so dread that not one single animal dares to disturb him while he's resting. He tiger has a fur striped with black, white and reddish-brown. He becomes invisible when he hides away in the long grass of the jungle. Thanks to his camouflage, he can approach his preys without been noticed. A tiger inspects is territory everyday. It takes him three days to go round and visit all his hiding-places. Intruders: beware! The anger of the master of this place can be violent!

How much do you know about penguins?

How much do you know about penguin facts? Check out it now. Here is general information about them from habitat to social struction

Magellanic Penguin

Penguin Habitat
Most penguins spend about ¾ of their time in the water. Their bodies are designed to easily adapt to the water.

Penguin Distribution
It is a common misconception that all penguins live in icy climates. While many of them do it isn’t something that is necessary in order for them to survive.

Penguin Feeding
The primary sources of food for penguins include krill, small fish, and crustaceans. Many species of penguins prefer to hunt near the shoreline.

Penguin Reproduction
There are some great qualities of penguins found in their reproduction process. They can mature for reproduction from about 4 to 8 years of age.

Penguin Anatomy
The overall anatomy of a penguin is very complex as well as interesting. Their bodies are designed to allow them to survive in their natural habitat.

Penguin Communication
Penguins are very effective communicators, especially with their mates. This is due to the fact that they have to work together in order to care for the eggs and for the offspring.

Penguin Evolution
It is believed that the penguins are derived from a type of bird that is able to fly. Yet they needed to be able to adapt to the waters if they were going to be able to survive.

Penguin Predators
There are quite a few types of predators out there that find penguins to make the perfect meal.

Penguin Social Structure
It is believed that it is their social status that allows them to be able to interact and to survive the harsh winters in many areas.

Facts that you didn't know about elephant facts of eating habits

What do African and Asian elephants eat?


The African elephant is much larger that the Asian elephant and consequently eats a lot more than the latter. While an average African elephant will need 250 kilograms of food and drink 60 liters of water the Asian elephant will eat 150 kilograms and drink 40 liters of water. Both species will feed mostly in the early morning and in the late evenings.

The African elephant is found in all types of habitats ranging from the savannahs to marshes and deserts and even in mountains above the snow line. Because of the terrain they live in and because of their higher reach they are browsers. They eat leaves, soft shoots, woody plants, shrubs and fruits of high growing trees. They will often rip bark off trees. They will often uproot trees, a habit which can change savannah into grasslands.

The Asian elephant lives in the thorn-scrub forests of Sri Lanka, Southern India and Thailand and in the evergreen forests and are grazers. They will generally feed on grasses, low woody plants and trees. As bamboo is abundant in these regions the Asian elephant is very fond of them.

How much do elephants eat?


An interesting fact is that elephants do not have a very efficient digestive system and they digest, on an average, only forty percent of the food they eat. That makes the quantity of food they require even larger. A large male African elephant may eat as much as 350 kilograms of vegetation in a day. They also have to drink a lot of water. Elephants may spend as much as 18 hours a day foraging for food and water. Because they consume such quantities, elephants live close to water as the live to the food source. They are also very good swimmers so they often swim in search of food from one place to another.
 For more facts tigers facts
Elephants have 26 teeth. Unlike most other mammals that first develop baby teeth that are later replaced by a set of permanent teeth elephants have cycles of tooth replacement throughout their lives and may be typically replaced six times in a lifespan. This helps them eat the tough tree barks and the roots till late into their lives. An elephant with an infected tooth cannot survive for long in the wild because it cannot eat properly, and tooth replacements help.

What make tiger becomes India's national animal?

Learn all information you wanted about tiger facts by this article:

The Tiger (Panthera Tigris,Linnaeus) is the national animal of India. Tiger is also called the lord of Jungles. The national animal of India, is rich-colored well-striped animal with a short coat. As the national animal of India, tiger symbolizes India's wildlife wealth. The combination of grace,strength, agility and enormous power has earned the tiger great respect and high esteem.


Out of the eight races of the species known, the Indian race, the Royal Bengal Tiger is found throughout the country (except the north-western region) and also in the neighboring countries like Nepal, Bhutan and Bangladesh. Tigers are now getting extinct. The Government of India, under its "Project Tiger" program, started a massive effort to preserve the tiger population in 1973. Today, the tiger advances as a symbol of India's conservation of itself and its wildlife heritage. Since the launch of "Project Tiger", the tiger population has shown a gradual increase. So far, 23 tiger reserves have been established in the country under this project.

The tiger was adopted as the National Animal by the Indian Board for Wildlife in 1972 in place of the lion. It was selected as a national animal because of its presence in larger parts of the country. It is found in 16 states while the lion is found only in one state. Also, because of the worldwide importance of the animal, and the need to protect it. Tiger as the National Animal of India symbolizes the power, strength, elegance, alertness, intelligence and endurance of the nation. Tiger has also been long part of Indian mythology and folklore.

How is a rainbow formed?


Most of us like to see rainbow, but how many of us know the science facts that how is a rainbow formed? See the writing to know more:



One of nature's most splendid masterpieces is the rainbow. A rainbow is an excellent demonstration of the dispersion of light and one more piece of evidence that visible light is composed of a spectrum of wavelengths, each associated with a distinct color. To view a rainbow, your back must be to the sun as you look at an approximately 40 degree angle above the ground into a region of the atmosphere with suspended droplets of water or even a light mist. Each individual droplet of water acts as a tiny prism that both disperses the light and reflects it back to your eye. As you sight into the sky, wavelengths of light associated with a specific color arrive at your eye from the collection of droplets. The net effect of the vast array of droplets is that a circular arc of ROYGBIV is seen across the sky. But just exactly how do the droplets of water disperse and reflect the light? And why does the pattern always appear as ROYGBIV from top to bottom? These are the questions that we will seek to understand on this page of The Physics Classroom Tutorial. To understand these questions, we will need to draw upon our understanding of refraction, internal reflection and dispersion.




The birth of each rainbow begins with millions of tiny rain droplets. The rain droplets serve as a type of reflector of light. White light enters one individual rain droplet and exits as one specific color of the spectrum. Without millions of rain droplets, a rainbow would not occur. If you only had a few rain droplets you would only see a few colors. This is typically why rainbow appear after a rain storm.
Each rain droplet has a function in the formation of the rainbow. Sunlight enters the rain droplet at a specific angle and the rain droplet separates the white light into many different colors. 


Kết quả hình ảnh cho why rainbow is formed

This angle is a fixed measurement between your eye and the sun. What color is refracted depends upon the critical angle, which is the angle the sunlight strikes the back of the rain droplet. Red light bends the least, exiting the rain droplet at a 42 degree angle, while Violet light bends the most, exiting the rain droplet at a 40 degree angle. All of the other colors of the rainbow exit the rain droplets at some angle between 40 and 42 degrees, thus making up the colors of the rainbow ROYGBIV, this order never changes.
Each rain droplet reflects all colors at a given point and time, but only one color comes back to your eye, requiring million of rain droplets to create a rainbow. As the rain droplets fall through the sky, the colors of the spectrum being reflected and refracted are constantly changing.

Top most poisonous snake in the world

Are you a animal facts lover? You know a lot of facts about them. So, do you know about top most poisonous snake in the world? Here is for you

10. Death Adder

Death Adder (Acanthophis antarcticus) / Photo: John Wombey, CSIRO

On name alone the death adder qualifies for a place on our list. However, the name actually started out as “deaf adders” as in the old days it was believed they couldn’t hear. The reason for this misconception was that unlike other snakes, which tend to slither away when a human approaches, the death adder doesn’t. This is because they are ambush hunters which lay in wait for their prey and so are less inclined to move.

Regardless of where the name comes from though, these are a very dangerous snake indeed. Their venom is some of the most powerful on earth and contains neurotoxins capable of causing paralysis of the respiratory system and death. As well as being armed with such lethal venom the death adder is just about the fastest striking snake you’ll find anywhere.

The death adder is found throughout much of Australia where it is considered less dangerous than the brown snakes. They are also found in Papua New Guinea and western Indonesia where they do unfortunately live up to their name and cause a significant number of deaths every year.

9. Coastal Taipan

Coastal Taipan (Oxyuranus scutellatus) / Photo: Denise Chan / License

It may seem strange that the most venomous snake on Earth (the inland taipan) did not make it onto the list whereas its less venomous cousin, the coastal taipan, did. Whilst the coastal taipan only (!) has the third most toxic venom of any land snake it is still phenomenally dangerous. Yes, admittedly it does only deliver sufficient venom to kill over 200,000 mice with a single bite – the inland taipan could theoretically kill over a million. But there are two important factors that I feel make the coastal taipan more dangerous; firstly it occurs in less remote regions than the rarely seen inland taipan and secondly the coastal taipan has a reputation as being somewhat aggressive.

When a coastal taipan feels the need to defend itself it goes into full attack mode. There is no messing around with ‘dry bites’, in over 80% of cases a large dose of venom is delivered, often in repeated strikes. Each of these rapid succession of bites is capable of injecting a similar amount of venom. With the longest fangs of any of Australia’s venomous snakes the taipan can inject its powerful neurotoxin deep into the victim’s tissues. Another of the taipan’s other reputed deadly traits is to actually chase people when on the attack, and it can move at a fair pace.

8. Common Lancehead

Common Lancehead (Bothrops atrox) / Photo: Greg Hume

The lanceheads are a family of pit-vipers (Bothrops) found throughout Central and South America. Together they are responsible for the vast majority of snakebite deaths in the region. Often living in populated areas these snakes are fast and described as excitable and unpredictable when encountered.

Worthy of particular mention amongst this group are the common lancehead (B. atrox), the terciopelo (B. asper) and the jararaca (B. jararaca). All are large snakes measuring around the 2 metre (6.5ft) mark and have powerful hemotoxic venom.

The bite from a lancehead will cause local swelling and pain often followed by blistering and bruising. Systemic symptoms usually involve hemorrhaging internally and from the gums, eyes etc. Whilst this may lead to fatal shock, death may also result from kidney failure.

7. Puff Adder

Puff Adder (Bitis arietans) Photo: Johannes van Rooyen

The puff adder makes up for a lack of length with an abundance of girth. These heavily built snakes are powerful and equipped with particularly long fangs which make them formidable hunters. Despite being so slow and lethargic as to be described as ‘lazy’, the puff adder actually has one of the fastest strikes of any snake. It has been known for a puff adder to kill its rodent prey just from the sheer force of its strike and its large fangs. That said, it carries enough venom to kill several humans.

The name puff adder comes from the snake’s warning behaviour in which it will inflate itself to look bigger and release an intimidating hiss. You are well advised to heed this warning as the puff adder is statistically Africa’s most dangerous snake causing more fatalities than any other reptile on the continent.

6. Blue Krait


This snake is not as well known as some, but its venom is 16 times more potent than that of the cobra! There also is no really good antivenin to use, which makes it quite deadly. The Blue Krait tends to keep to itself and usually only comes out at night, though, so it is generally easy to avoid.

5. Indian Krait


Common krait (Bungarus caeruleus)

This small snake is our second member of the “big four”. Also known as the common krait or blue krait they are responsible for causing an estimated 10,000 deaths a year in India alone.

The krait’s weapon is its powerful neurotoxic venom. It is one of the top five most venomous land snakes, only slightly less so than the coastal taipan. Whilst its small size means it can potentially deliver less venom a bite still contains sufficient toxins to kill several people. To make sure a good dose is delivered the krait typically hangs on to its victim for a while.

4. Inland Taipan


While it’s difficult to be as impressed by the Inland Taipan after learning about the concentration of venom in a Belcher’s Sea Snake bite, it’d be foolish to discount the Taipan just because its bite can only kill as many as 100 people! Taipans usually avoid human contact, however, and you are unlikely to ever encounter ones

3. Saw-Scaled Viper

Saw-scaled viper (Echis carinatus) / Photo: Vassil

Another of India’s “Big Four” snakes the saw-scaled viper is responsible for countless thousands of deaths throughout southern Asia. Although it is small in size (usually less than 30ins / 80cm in length) this snake makes up for it in numbers. One of the commonest snakes throughout India and Sri Lanka the saw-scaled viper is the bane of agricultural workers.

Not only is this snake common, it is very dangerous. Powerful venom, an incredibly fast strike and a notoriously bad temper combine to make the saw-scaled viper responsible for somewhere in the region of 5,000 fatalities a year in India alone. If you extrapolate this number across the viper’s range, which stretches across the Indian subcontinent and into the Middle East and Africa, then this snake is one of the planet’s biggest killers.

2. Black Mamba

Black Mamba (Dendroaspis polylepis)

Not only is the black mamba one of the most venomous snakes on the planet it is also big (up to 4 metres / 13ft), fast (11kph / 6.8mph) and highly aggressive. When attacking the mamba can strike with both speed and over a considerable distance; it is also known to deliver multiple bites on occasion. Given all these characteristics it is little surprise the black mamba is also arguably the deadliest snake in the world.

The only reason the black mamba doesn’t head up our list is that it is not widespread throughout the more densely populated areas of the developing world. In every single country this snake is indigenous it has the highest mortality rate of any snake. For example in South Africa the black mamba is responsible for less than 1% of all snakebites yet still kills the most people.

1. Belcher’s Sea Snake

Belcher’s Sea Snake (Cal Donovam/Flickr)

You may be somewhat familiar with these sea snakes. They are quite common, and you may have seen them in films or even in person. They are recognizable from their stripes. Usually these snakes have no interest in confrontation, but if one feels threatened, it may bite you. Three out of four times this will be no big deal, since only about one quarter of Belcher’s Sea Snakes carry venom. Those that do though have the highest concentration of venom in existence. Just a few milligrams has the capacity to kill thousands of human beings, making this the most poisonous snake in the world. Nonetheless, most Belcher’s Sea Snakes are quite harmless thanks to a docile personality and a lack of venom.

Why can birds fly?

If you are a person who love to know animal facts and want to know more. Here is answers some question about why birds can fly:

Résultat de recherche d'images pour "why do birds fly"

The pressure exerted down by fast moving air (red arrows) is less than the pressure exerted up by slow moving air (green arrows).
If you tried the paper activity from the front of this article, you might have been surprised by what happened. In most cases a person would think the paper would go down and not lift up when they blow air across the top.
It may not be what you would expect, but it is what birds and planes do to lift off the ground and fly. Blowing faster-moving air above the sheet paper lowered the air pressure above the paper. Now the air pressure below the paper is higher and creates lift. Lift does exactly what it sounds like; it lifts objects off the ground when everything is just right

Bird bodies are made to fly. They have light bones, strong legs, and specially shaped wings. Flying helps birds get away from animals that want to eat them, and makes them better hunters, too. Flying also helps them travel from cold places to warm places, called migration(my-GRAY-shun).


Résultat de recherche d'images pour "why do birds fly"

Flying birds have:
  • Lightweight, smooth feathers – this reduces the forces of weight and drag
  • A beak, instead of heavy, bony jaws and teeth – this reduces the force of weight
  • An enlarged breastbone called a sternum for flight muscle attachment – this helps with the force of thrust
  • Light bones – a bird’s bones are basically hollow with air sacs and thin, tiny cross pieces to make bones stronger – this reduces the force of weight
  • A rigid skeleton to provide firm attachments for powerful flight muscles – this helps with the force of thrust
  • A streamlined body – this helps reduce the force of drag
  • Wings – these enable the force of lift.
