How many facts did you know about Dove?

How many facts did you know about Dove? I love to know and share amazing information about Dove as this below article.

#1

Dove can get easily adjusted in almost every kind of environment. So, we can find they everywhere except the truly harsh areas, like desert and Antarctica. How much do you know about tiger facts for kids ?

#2

Like all birds, Mourning Doves are unable to sweat, so to stay cool during hot weather. They pant just like a dog. Panting requires the doves to drink a great deal of water due the excessive loss of moisture to evaporation.

#3 

Mourning Doves produce a mournful cooing sound which is probably responsible for its memorable common name.

#4 

The names Pigeon and Dove are often used interchangeably. That might be one of the most awesome animal facts you had no idea before. In fact, in many languages, these terms are translated exactly the same. Pigeons and Doves belong to the same family, Columbidae, and have many similar features.

#5 

In Christianity, the dove is a common Christian symbol to embody the Holy Spirit. The Christian symbol of a dove with an olive branch in its beak represents peace.

#6

As with most birds, doves will primarily feed on seeds, nuts and fruits. Interesting, the species can actually be divided in terms of doves that primarily feast on seeds (granivorous) and the other family of dove, the frugivorous species, where fruit is the primary source of nutrition.

#7

Doves and Pigeons have no gall bladder. Although the reason behind this anomaly in unknown, interestingly, these birds still produce bile.

#8 

Both the male and the female produce milk for their young. Their milk is called crop milk. It contains a higher level of protein and fat than the milk produced by mammals.

#9 

Life span of dove in the wild is 1.5 years for adults. However, doves lifespan in captivity can exceed 20 years. Check out my list of fun, weird and just plain amazing fact of life I have found.

#10

When they lay eggs, it is usually just two. Incubation takes just two weeks.

Why Pigs Need Mud

Why Pigs need mud? Can you give us the best explaination? If you can't, let's find out here to know and also get other fact of life I have found as below

Pigs roll in mud primarily in order to regulate their body temperature. This behavior is more commonly referred to as "wallowing."

As well as offering protection from the sun's rays, a coating of moist mud is crucial for keeping pigs cool in warm weather through gradual evaporation. This method is so effective that some have suggested wallowing as the reason for the limited evolutionary development of sweat glands in pigs. Pigs also wallow in cooler weather, indicating additional motivations such as the removal of parasites, and possibly marking territory with scent. Of course, pigs also genuinely enjoy wallowing for its own sake, showing signs of distress when farmers attempt to curb their behavior with anti-parasite medicines or air-conditioned barns.

A wide range of Pangolin facts

Below is a wide range of Pangolin facts and their physical characteristics

Pangolin species vary in size from about 1.6kg (~3.5 lbs) to a maximum of about 33kg (~73 lbs). They vary in color from light to yellowish brown through olive to dark brown. Protective, overlapping scales cover most of their bodies. That might be one of the most awesome animals facts you had no idea before. These scales are made from keratin — the same protein that forms human hair and finger nails. Overlapping like artichoke leaves, the scales grow throughout the life of a pangolin just like hair; scale edges are constantly filed down as pangolins dig burrows and tunnel through the soil in search of termites and ants. Pangolin undersides do not have scales, and are covered with sparse fur. Unlike African pangolins, Asian pangolins also have thick bristles that emerge from between their scales.

With small conical heads and jaws lacking teeth, pangolins have amazingly long, muscular, and sticky tongues that are perfect for reaching and lapping up ants and termites in deep cavities. Pangolins have poor vision, so they locate termite and ant nests with their strong sense of smell. A pangolin’s tongue is attached near its pelvis and last pair of ribs, and when fully extended is longer than the animal’s head and body. At rest a pangolin’s tongue retracts into a sheath in its chest cavity. A pangolin’s stomach is muscular and has keratinous spines projecting into its interior. Usually containing small stones, the stomach mashes and grinds prey in much the same manner as a bird’s gizzard. Wanna take a quick look at funny pictures with captions that can help you relax effectively.

Pangolin limbs are stout and well adapted for digging. Each paw has five toes, and their forefeet have three long, curved, claws used to demolish the nests of termites and ants and to dig nesting and sleeping burrows. Pangolins shuffle on all four limbs, balancing on the outer edges of their forefeet and tucking their foreclaws underneath as they walk. They can run surprisingly fast, and will often rise on their hind limbs to sniff the air. Pangolins are also capable swimmers, and while some pangolin species such as the African ground pangolin (Manis temmincki) are completely terrestrial, others, such as the African tree pangolin (Manis tricuspis), are adept climbers, using their claws and semi-prehensile tails to grip bark and scale trees.

Facts and infor about seed plants

Facts and infor about seed plants are all shown here. Let's have a view at it now.

INSIDE A SEED

A seed is the first stage in the life cycle of a plant. Protected inside the tough seed coat, or testa, is the baby plant, called an embryo. Food, which fuels germination and growth, is either packed around the embryo or stored in special seed leaves, called cotyledons.

SPREADING WITHOUT SEEDS

Seeds are not the only means of reproduction. Some plants create offshoots of themselves – in the form of bulbs, tubers, corms, or rhizomes – that can grow into new plants. This type of reproduction is called vegetative reproduction. As only one parent plant is needed, the offspring is a clone of its parent. This might be one of the most weird facts about them.

 

Bulb

A bulb is an underground bud with swollen leaf bases. Its food store allows flowers and leaves to grow quickly. New bulbs develop around the old one.

Tuber

A tuber is a swollen stem or root with buds on its surface. When conditions are right, the tuber’s food store allows the buds to grow. Still boring? Check out our funny images to get relaxing moments in your freetime.

 

Corm

A corm is a swollen underground stem that provides energy for a growing bud. After the food in the old corm is used up, a new corm forms above it.

Rhizome

A rhizome is a horizontal stem that grows underground or on the surface. It divides and produces new buds and shoots along its branches.

GERMINATION OF A RUNNER BEAN

Most seeds require damp, warm conditions in order to sprout. During germination, the seed absorbs water and the embryo starts to use its food store. A young root, or radicle, begins to grow downward. Then a young shoot, or plumule, grows upward. This develops into the stem and produces leaves. The first leaves, called seed leaves or cotyledons, fuel the early growth until the plant’s true leaves appear.

FRUITS

A flower’s ovary usually develops into a fruit to protect the seeds and help disperse them. A fruit may be succulent (fleshy) or dry. Fruit is often tasty and colourful to attract fruit-eating animals. Its seeds can pass through an animal unharmed, falling to the ground in droppings. Seeds may also be dispersed on animals’ coats, by the wind, or by the fruit bursting open.

DRY FRUITS

The seeds of dry fruits are dispersed in various ways. Peapods are dry fruits that split and shoot out their seeds by force. The hogweed fruit forms a papery wing around the seed, helping it to float on the breeze. The strawberry is a false fruit, but it is covered by tiny dry fruits, each with a seed.

SUCCULENT FRUITS

Fleshy, brightly coloured, and often scented, succulent fruits are designed to attract the animals that eat and disperse them. Fleshy fruits such as apricots and cherries have a woody stone or pip that protects the seed. Called drupes, these fruits form from a single ovary. Many drupes, formed from many ovaries, may cluster to form a compound fruit, such as a raspberry.

1. There are thousands of other planets out there.

We have eight planets in our Solar System. However, outside of our Solar System there are thousands of other planets. The extra-solar planets or exo-planets are in orbit around another star. So far we have almost 1800 confirmed new worlds, with another 3000 awaiting confirmation. Astronomers are looking to a star’s goldilocks zone for planets that may be habitable, just like the Earth. The majority of planets discovered so far are hot gas giant planets.

2. In space the skin on your feet peels off!

This is a pretty gross fact but in the micro-gravity environment, astronauts are not using their feet to walk. Therefore the skin on their feet starts to soften and flakes off. As laundry facilities do not exist in space, astronauts will wear the same underwear and socks for a few days. Those socks then need to be taken off very gently. If not those dead skin cells will float around in the weightless environment.

3. On Venus a day is longer than a year.

This is tricky one to get your head around but a year on Venus (that is the length of time it takes to complete one whole orbit around the Sun) is 224.7 Earth days. However it takes 243 Earth days to rotate on its axis just once.

4. The astronauts were placed in quarantine after returning from the moon.

There is a famous image of President Nixon talking to the Apollo 11 crew consisting of Michael Collins, Neil Armstrong and Buzz Aldrin. This continued until after the Apollo 14 crew returned safely. After this it was decided that the Moon did not contain any deadly diseases. The Apollo 13 crew, who had a malfunction and had to return to Earth, did not have to be quarantined after their re-entry as they didn’t actually walk on the moon. This is one of the most amazing facts ever.

5. One million Earths can fit inside the Sun.

Ancient astronomers once believed the Earth was at the centre of the Universe but now we know that the Sun is at the centre of our Solar System and our planets orbit the Sun. The Sun makes up 99.8% of the entire mass of the whole Solar System. One million Earths would be needed to be the same size as the Sun.

6.You become taller in Space.

Another change to the human body in micro-gravity is that spine straightens out, as gravity is not pushing you down. In fact you can be up to as much as 5cm taller in the Space Station.

7. Extreme weather warning!

Some times on the Earth, especially here in Northern Ireland the weather can be a bit rubbish! However our weather is awesome compared to some of the other planets. Jupiter has fast winds and the Great Red spot, a massive hurricane style storm, has raged there for the last 300 years. Mercury and Mars have extreme temperature changes in the same day. Venus is a scorching five times hotter than boiling water. Saturn and Uranus also have extremely fast winds. However Neptune has the fastest ever wind speeds reaching a staggering 1600mph!

8. Space is not that far away.

Space officially begins at the universal marker of the Karman Line. This invisible boundary is 100km above the Earth. In theory if you could drive your car upwards, you could be in space in less than hour.

A list of interesting rainbow facts

How much did you know about science facts? Can you list interesting rainbow facts? Keep reading to know. A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

Fact #1

A rainbow is a multi-colored arc that forms in the sky.

Fact #2

How do rainbows form? Rainbows are created by both reflection and refraction (bending) of light in water droplets in the atmosphere, which results in a spectrum of light appearing.

Fact #3

The main rainbow colours in order are Red, Orange, Yellow, Green, Blue, Indigo, and Violet (the acronym or name ROY G BIV is also a good way to remember these colors as well as their order). Sir Isaac Newton identified the 7 colors of the visible spectrum that together make up white light. And all of which are present in a rainbow in the order ). Legend has it that Newton included indigo because he felt that there should be seven rather than six coloursin a rainbow because of his strong religious beliefs.

Fact #4

These 7 colours in the rainbow are just the main ones. Actually, a rainbow is made up of an entire range of colours, any colour you have ever seen, even colours you haven’t seen! Nobody sees colors the same, our eyes react differently depending on how much light there is. Therefore, some people may see more colors than what you see. This is one of the most amazing factswe've heard. 

Fact #5

In fact, a rainbow is a full circle of light. However, because of most people viewing a rainbowon the ground, we can only see a semi-circle or arc of the rainbow.

Fact #6

A "double rainbow" is where a second, much fainter arc can be seen outside of the primary arc. This is caused by the light reflecting twice inside the water droplets. As a result of this double reflection the colors of the second arc are inverted with violet on the outer edge and red on the inner edge.

Fact #7

No two people see the same rainbow. If someone appears to be standing under a rainbowyou can see, they will see a different rainbow at the same angle but further away.

Fact #8

A rainbow is not an object so it can’t be approached or physically touched.

Fact #9

Rainbows can be seen not just in the rain but also in the mist, in the spray of water from the ocean, fog, and dew, whenever there are water drops in the air and light shining from behind at the right angle.

Fact #10

Rainbows can also be seen during night-time. Moonlight can produce enough light to create a rainbow at night. This is a “lunar rainbow” or “moonbow”. Moonbows are rare because moonlight is not very bright.

Fact #11

A rainbow is not situated at a specified distance, instead it will always be visible to a person at the precise angle freshwater droplets reflect the light which is 42 degrees in the opposite direction of the sun.

Fact #12

A "fogbow" is formed by cloud and fog droplets, they are almost white with very faint colors visible. Fogbows are quite large and much broader than a rainbow. Here're not jokes to be funny, it's the truth.

Fact #13

An old European belief is that anyone passing underneath a rainbow would be changed from a man into a woman or vice versa. The idea that a pot of gold can be found at the rainbow’s end originated in old Europe. In a place called Silesia it was said that the angels put the gold there and that only a nude man could obtain the prize. Unfortunately, scientists says this is impossible to do.

Fact #14

Rainbows are the universal symbol of peace and harmony.

Fact #15

Most rainbows we see will be a "primary rainbow" whereby the red colour can be seen on the outer edge through to violet on the inner edge.

World Series quick facts that will amaze you

Let's check out our rich source of World Series quick facts, sport facts

1. Championship Game Predates World Series

Prior to the first World Series in 1903 and from 1884-1890, an Exhibition Series occurred between the champions of the National League and the American Association (a rival association that folded in 1891). The event was disorganized and thrown together by the teams themselves. Sometimes the Series lasted three games and others as many as 15. When the American Association dissolved, the National League continued as the only league.

2. Only one “world champion” team didn’t come from the United States

Despite the competition’s all-inclusive name, only one team not based in the United States has won the World Series: the Toronto Blue Jays, victors in both 1992 and 1993. Only one other international team—the now-defunct Montreal Expos—has ever even played in the major leagues, though they never appeared in the Fall Classic. Though there are talks of expanding into Mexico or other nearby countries (travel time makes a truly international sport difficult), an American “world champion” is a virtual guarantee for now.

3. Only One No-Hitter

It is the fact that Yankees’ pitcher Don Larsen recorded the only no-hitter (in this case a perfect game) in World Series history during Game 5 of the 1956 Series.

4. Most Consecutive Scoreless Innings Pitched was 33

With 33 consecutive scoreless innings pitched, Whitey Ford holds the World Series record. Previously, the record holder was Babe Ruth, who pitched 29 2/3.

5. World Series was Cancelled Twice 

The player’s strike in 1994 cancelled that year’s Fall Classic, while a rivalry between the Boston Pilgrims and the New York Giants ended the 1904 Series. During World War II, the Series continued, however many of the best players fought overseas and were missing from the games. In 1943, the New York Yankees won the Series without Hall of Famers Joe DiMaggio, Phil Rizzuto, and Red Ruffing.

6. First Pinch-Hit Home Run was in 1947

Yogi Berra hit the first pinch-hit home run in World Series history in Game 3 of the 1947 World Series against the Dodgers’ pitcher, Ralph Branca. The Yankees lost the game, but won the Series in seven games.

7. Managers with 7 Wins had the Most in a World Series 

Former Yankee managers, Joe McCarthy and Casey Stengel, set the record with each winning seven World Series games during their managerial careers.

8. It’s a Small World

It may be called the World Series, but it doesn’t seem like the rest of the world gets to play. The Toronto Blue Jays are the only team outside the US to have won the World Series – they were back-to-back champions in 1992 and 1993.

9. Most Stolen Bases was in 1967

Super-fast Lou Brock from the Cardinals set the single-season record with seven stolen bases in the 1967 World Series and in 1968 he tied it. He also shares with Eddie Collins the largest number of career stolen bases in the World Series, 14.

10. Before Championship Rings, Players took Home Watches or Medallions

Since 1967, the winner of the World Series has received the Commissioner’s Trophy and traditionally each winning team has presented its members with championship rings. Previously, players were given pocket watches or medallions. In 1922, the New York Giants became the first team to issue rings.

Aboves are the selected facts on World Series from factoflife that can help you know more about this.

Tortoises facts

Animal facts: How many Tortoises facts do you know? Let's check here

1. A TORTOISE IS A TURTLE, BUT A TURTLE ISN'T A TORTOISE.

A turtle is any shelled reptile belonging to the order Chelonii. The term "tortoise" is more specific, referring to terrestrial turtles. (Of course, there's always an exception. In this case, the land-dwelling box turtle.) Tortoises are usually herbivorous and can't swim.

One easy way to tell 'em apart: look at their feet and shells. Water turtles have flippers or webbed feet with long claws, and their shells are flatter and more streamlined. Tortoises have stubby, elephant-like feet and heavier, domed shells.

2. A GROUP OF TORTOISES IS CALLED A CREEP.

But you won't see a creep very often. (Not that kind, anyway.) Tortoises are solitary roamers. Some mother tortoises are protective of their nests, but they don't care for their young after they hatch.

3. TORTOISES INSPIRED THE ANCIENT ROMAN MILITARY.

During seiges, soldiers would get in testudo formation, named after the Latin word for tortoise. The men formed rows and held shields in front or above them to completely shelter the unit.

4. "TESTUDINAL" MEANS "PERTAINING TO OR RESEMBLING A TORTOISE OR TORTOISE SHELL."

5. TORTOISES HAVE AN EXOSKELETON AND AN ENDOSKELETON.

The shell has three main parts: the top carapace, the bottom plastron, and the bridge that fuses these pieces together. You can't see them, but every tortoise has ribs, a collar bone, and a spine inside its shell.

6. THE SCALES ON THE CARAPACE ARE CALLED SCUTES.

Made of the same keratin found in fingernails and hooves, scutes protect the bony plates of the shell from injury and infection. The growth rings around scutes can be counted to determine the approximate age of wild tortoises.

7. THE LIGHTER THE SHELL, THE WARMER THE ORIGIN.

Tortoises from hot places tend to have lighter-colored shells than tortoises from cooler areas. The light tan sulcata originates from the southern part of the Sahara Desert.

8. THEY CAN'T SWIM, BUT TORTOISES CAN HOLD THEIR BREATH FOR A LONG TIME.

They're extremely tolerant of carbon dioxide. It's a good thing—tortoises have to empty their lungs before they can go into their shells. You'll often hear them exhale when they're startled and decide to hide.

9. AND YES, THEIR SHELLS ARE SENSITIVE TO TOUCH.

Shells have nerve endings, so tortoises can feel every rub, pet, or scratch ... and sometimes they love it. Note: This delightful creature is a turtle, not a tortoise.

10. SULCATAS ARE ONE OF THE MOST POPULAR PET TORTOISES—AND ONE OF THE BIGGEST.

Get ready to move to the suburbs and amend your will. Sulcatas are the third largest tortoise species in the world, behind the Galapagos and Aldabra giant tortoise. They can live more than 100 years and weigh up to 200 pounds.

What sound do giraffes make?

Do you know what sound do giraffe, giraffe baby make? Can you guess the answer? Let's see for the answer with evidences for this awesome question

The researchers suspected the reason no one heard giraffe communication was because the sound frequency was too low for humans to hear. Elephants and other large animals use an ultra-low frequency “rumble” for long-distance communication; why not giraffes?

Giraffes very rarely make sounds, but they do have the ability to make noises such as moos, snorts, hisses, grunts and flute-like sounds. It has been suggested through various studies that the sounds giraffes make are often below the level of human hearing. Therefore, it is a common misconception that they do not have voices.

If a giraffe is startled or feels threatened, it may make a snorting sound, or it may just wander off. In the wild, giraffes often indicate to other animals that danger is nearby, and when a giraffe herd takes off, most other animals willfollow. Humans, lions and crocodiles are the only species that hunt giraffes.

Elephants run

If you’re looking for the most interesting animal facts, you’re at the right place. Here areamazing facts about elephants for kids: Can elephants run?

A charging elephant might not look like it's merely walking, but that's exactly what it may be doing. Surprisingly, scientists don't agree on whether elephants run in the traditional sense. Now a new study splits the difference, suggesting that a rushing elephant may be walking and running at the same time.

Elephants break all the rules of animal movement. Most four-legged vertebrates change their stride when they move at high speeds so that all four feet leave the ground at once. Elephants take faster and longer steps, but they never take all four feet off the ground. That helps them spread out their massive weight as much as possible, says Norman Heglund, a biomechanics expert at the Catholic University of Louvain in Belgium. But then, are they really running?

That's been a tough question to answer. It turns out there's a lot more involved in running than just taking one's feet off the ground. The legs also flex in particular ways that change an animal's center of gravity and the force it exerts on the ground. Scientists can measure these changes in humans and other animals by making them walk across force sensing plates. But just try doing that with a 4000-kilogram elephant.

The closest researchers have come is high-speed video of rushing elephants analyzed by a team of researchers in 2003. John Hutchinson, a biologist of the University of London's Royal Veterinary College, and colleagues concluded from the footage that, when elephants move at high speeds, their back legs bend slightly, like a runner springing from step to step. But scientists wanted to see more quantitative data.

So in the new study, Heglund and colleagues engineered a heavy-duty force-sensing plate that could withstand being trampled by a charging elephant. They shipped sixteen of the plates, along with computers and video cameras to the Thai Elephant Conservation Center in Lampang Province. There, they constructed a 2 meter by 8 meter track from the plates and filmed 34 elephants, each guided by a mounted trainer, as they traversed the track at a range of speeds.
For more facts: tiger facts for kids

Despite their size, elephants step lightly, the team reports today in The Journal of Experimental Biology. A human runner exerts peak forces of 3 times his or her body weight when running, while elephants exert at most 1.4 times their body weight. They also don't move their center of gravity much: Even at an 18 kilometer-per-hour charge, an elephant's center of mass moves up and down by about a centimeter, a smaller vertical movement than human runners make.

As to whether elephants actually run, the answer seems to be, well, sort of. While Hutchinson's team saw that an elephants' front legs walked while the back legs trotted, Heglund's team's measurements indicated the opposite: When stepping with a forelimb, the elephants' center of mass lowered slightly as the force on the ground increased, indicating a spring-like mechanism typical of a dog or a human's run. Meanwhile, even at high speeds, the elephants' back legs seemed to stay rigid, which is typical of a walk. "They don't really run in the classical sense," Heglund says. "They can't quite kick it into second gear, so they're stuck halfway in between" a walk and a run.

But that may not be the final answer, warns Hutchinson, who studied the same group of elephants alongside Heglund's team. He says that the elephants' feet likely touched more than one plate at once, making it hard to separate what individual limbs were doing. Still, he says, the research is important because it quantifies the forces with which elephants hit the ground. "It's nice to have the numbers."

If nothing else, the study illustrates that, when it comes to running in animals, "it's not one size fits all," says Daniel Schmitt, an expert in primate locomotion at Duke University in Durham, North Carolina. "That speaks to how evolution works."

Percentage similarity between humans and animals in of genetic

Here is one of the most amazing science facts: Percentage similarity between humans and animals in of genetic 

It is very difficult to find reliable data comparing the human genome to animal genome. The principal reason is that few animals have had their full genome sequenced. Even those that have cannot be easily compared in terms of percentages because the genomic length and chromosomal division can vary greatly from one species to another.

Scouring the Web, here is what I have found so far.

- Genome-wide variation from one human being to another can be up to 0.5% (99.5% similarity)

- Chimpanzees are 96% to 98% similar to humans, depending on how it is calculated.

- Cats have 90% of homologous genes with humans, 82% with dogs, 80% with cows, 79% with chimpanzees, 69% with rats and 67% with mice. 

- Cows (Bos taurus) are 80% genetically similar to humans.

- 75% of mouse genes have equivalents in humans (source), 90% of the mouse genome could be lined up with a region on the human genome (source) 99% of mouse genes turn out to have analogues in humans 

- The fruit fly (Drosophila) shares about 60% of its DNA with humans.

- About 60% of chicken genes correspond to a similar human gene.

Amazing Facts On Elephants

Would you like to see some elephant facts in your freetime? I believe that these following facts will be interested to you:

1. An elephant is one of the few four legged animals, which cannot run or jump.
2. At birth, the baby elephants are blind and they depend on their trunk and their mothers to help them.
3. Females can mate and have babies until they are around 50 years old, and they tend to give birth every 2.5 to 4 years.
4. Elephants feed around 16 hours a day and they consume around 300 to 600 pounds of vegetation every day.
5. Male elephants go through bouts of aggression, which last for short periods.  Hence, female elephants are kept at the zoos and used in the circus, as they are gentler in nature.
6. Elephants are social animals and they are often seen touching and caressing one another and playing around with the trunks.
7. An elephants tusk grows up to around 10 feet and weighs around 200 pounds.
8. There are two recognised species (types) of elephants the African elephant and the Asian elephant. The Indian elephant is a sub species of the Asian elephant. Elephants live in areas of Africa, Southern and Southeast Asia
9. The elephant is the national animal of Thailand.
10. A newborn elephant is able to stand up on its feet very soon after it’s born.
11. An elephant’s trunk has more than 40,000 muscles in it and no bones, which give it the flexibility. However, the trunk can get very heavy at times. So, the elephants are seen to rest it on their tusk.
12. Elephants consume around 15 quarts of water at a time.
13. As the elephants rely on one tusk more than the other, usually one tusk goes through the grinding leading to one being longer than the other.
14. Elephants use their trunks as a hose pipe by filling their trunks and then pouring the water in the mouth.
15. African and Asian elephants differ in several ways, but the variation in ears is commonly used to differentiate them. Some say that African species have ears that look like a map of Africa, and the Asian species have smaller ears that look like a map of India. Other differences include the body size, African elephants are much bigger and heavier, the skin is more wrinkled and tusks larger. The tip on the trunk of an African elephant has two prong like tips which are used to grasp objects whereas the Asian elephant has only one
16. Elephants walk behind each other in a single line when they are travelling.
17. An elephant poops around 80 pounds of feces in a day.
18. The elephant rests by raising one foot and crossing it behind the other one.
19. Just like dolphins and parrots, the elephant can also do mimicry. Some elephants in Kenya who were raised near the highway were heard to make truck sounds.
20. On an average, the elephant sleeps for around 2 hours in a day.

Trunk helps an elephant access better quality food

Do you know what  trunk helps an elephant access better quality food? Let's see for much more amaing informaion!
The elephant got its trunk, the story goes, because one small elephant child was so curious as to what a hungry crocodile ate for dinner that he got too close to it. The crocodile then bit and pulled its bulgy nose and stretched it out.

From then on, the elephant child was able to stuff large bundles of grass into its mouth with ease.

The truth, of course, is likely to be different to Rudyard Kipling's elephant child story.

And now researchers have sought to understand exactly what that is; and establish why elephants and giraffes have such long trunks and tongues.

The answer lies with the amount of food they need to eat, a new study suggests. It's published in the journal Acta Zoologica.

A team modelled how the tongues and trunks of 18 species of herbivore related to the amount of food they took in while grazing.

The soft body parts – the lips tongues and trunks - are the key to their survival

The elephant's trunk, they found, was vital for it to eat enough food in relation to the size of its mouth. So too was the giraffe's tongue. They also helped the herbivores eat softer, more nutritious plants such as leaves.

The team used a modelling process called allometric scaling, a well-known biological "law" which states that the size of an animal is in proportion to how much it eats.

How much they can bite in one go (bite volume) is therefore a direct result of these elongated soft mouth parts. Smaller herbivores such as an antelope do not need a large tongue to eat enough food.

Not only are these structures key to the survival of today's elephants and giraffes, the team further proposes that they evolved as a direct adaptation to the quality of edible plants in their environment.

It may also explain why some larger herbivores went extinct, says de Boer. During times of sudden climate change, when food became scarcer or less nutritious, other species may have lacked suitable tongues or trunks to eat enough food to survive.

However, as soft tissue is not preserved in the fossil record, other researchers maintain there's more to how tongues and trunks developed.

Palaeontologist William Sanders from the University of Michigan, US, is not convinced that this new analysis answers other aspects of herbivore development which could have played equally important roles in tongue and trunk evolution.

The size of an animal's teeth, how it replaces them in its mouth, and how an animal's guts work, would all influence how it eats, and have an impact on the evolution of trunks or tongues.

"Skulls, faces and mouths are formed of interrelated anatomical complexes, and that evolution of one part of these complexes will almost always have an effect on the others," he says.

About eight million years ago, elephant ancestors relied heavily on grazing from the ground but they had two sets of elongated tusks which prevented them from eating with only their mouths.

The elephant trunk, he says, evolved to such a length to accommodate its large tusks.

So in one aspect of his story Kipling was not so far off after all. The elephant child certainly could eat more with its elongated trunk as can all other elephants alive today.

Some awesome Bengal tiger facts

 Here are some interesting tiger facts for you:

The Bengal Tiger is one of the largest species of tigers in the world. They are also the one that offers the highest number of them in the wild. Don’t get to excited though as they are still at a high risk of being endangered. There are only about 2,500 of them in the wild.

What is also interesting is that there is about 1% which are DNA verified hybrids. They have one parent that is a Bengal Tiger and one that is a Siberian Tiger. These hybrid tigers seem to do quite well in the wild with most of the males being sterile. It is believed that this genetic link though was the result of mistakes in breeding while in captivity and then released to the wild instead of a natural occurrence that takes place in the wild. You may find many similarities between the Bengal Tiger and the Siberian Tiger.

The biggest threat to the in India is that their natural habitat continues to be cut away by logging companies. As a result they struggle to survive in less area and with less prey to feed upon. Finding enough water is a common problem for them as well. This is because the former is a subspecies off the latter.

This particular species of tiger can weigh up to 500 pounds for a full grown male and about 310 pounds for a full grown female. They also feature very long tails and heads that are larger than that of other species. They are excellent hunters and feed on a variety of prey found around India. They include deer, antelope, hogs and buffalo. They have also been seen consuming monkeys, birds, and other small prey when their main food selections become scarce.

In some areas there has been a problem with the Bengal Tiger eating livestock as well. Humans continue to try to live in these areas that used to be home to the tigers. Then they wonder why the animals they are raising become meals for them. Many of these ranchers engage in the illegal killing of tigers too so that they can protect their investment in such livestock.

There have also been reports of the Bengal Tiger killing and eating humans. However, most tigers avoid humans and this doesn’t happen regularly. They tend to consume up to 60 pounds of food at one time.

It is estimated that less than 2,500 of the Bengal tigers remain at this time. This is less than half of what the population was just 10 years ago. As a result there is a very aggressive protection plan in place for them. The efforts are working to an extent but poaching of these tigers is still a huge concern.

The Wildlife Protection Society of India continues to strive to look into all allegations of tiger poaching. They have confiscated large amounts of tiger parts and pelts but it is often hard for them to get to the source of who is actually responsible for killing and for shipping them. Even though they detain those caught with them there are more people involved in the process than they are able to uncover.

To get away with poaching though many of these hunters have resorted to poisoning the tigers. Then they are found already dead and they can’t be held responsible for killing them. This is also the same practices that many of the ranchers engage in as well.
