How did giraffes get so tall?

Learn all information you wanted about animals by this article, about giraffes, baby giraffe and how did they get so tall?

A giraffe's height is an evolutionary adaptation that allows it to feed from tall trees and other sources of vegetation. The long tongue of the giraffe, which can grow to 21 inches in length, is a similar adaptation designed for reaching difficult spots.

Giraffes can grow up to 19 feet in height and weigh nearly 3,000 pounds. While the giraffe's height is advantageous for eating and searching for predators, it also poses difficulty when the animal needs to drink from a watering hole. When kneeling, a giraffe must splay its legs, making the giraffe vulnerable to predators such as lions and crocodiles. Despite this, giraffes rarely need to drink and derive most of their water from vegetation.

There are two main scientific theories as to why giraffes’ necks are so tall. The first was proposed by Charles Darwin and suggests that due to intense competition from rival creatures for foliage under two metres high, giraffes’ common ancestor slowly evolved a longer neck in order to access untapped leaf reserves – with only the more successful, longer necked animals feeding efficiently. The second theory is that giraffes evolved long necks as a secondary sexual characteristic, giving males an advantage in physical combat and therefore granting access to more sexually receptive females to reproduce.

Are there any disadvantages of being so tall? Actually, there are none! Giraffes rarely drink water, so they don't have to inconvenience themselves by spreading their front legs wide apart, bending their knees, and lowering their necks all the time. How do they survive then? Well, giraffes can get all the moisture they need from simply licking dew and eating plants. Because they can survive for a long time without drinking water, they don't have to join other savannah animals that migrate to other areas during the dry season.

Vitamin C can help reduce stress

Learn the way to reduce stress by through this writing: vitamin c can help reduce stress

It's already everybody's favorite nutritional supplement, linked, however controversially, to preventing the common cold and fighting cancer. But vitamin C recently added a new notch on its belt. The vitamin helps reduce both the physical and psychological effects ofstress on people.

People who have high levels of vitamin C do not show the expected mental and physical signs of stress when subjected to acute psychological challenges. What's more, they bounce back from stressful situations faster than people with low levels of vitamin C in their blood.

In one study German researchers subjected 120 people to a sure-fire stressor—a public speaking task combined with math problems. Half of those studied were given 1,000 mg of vitamin C. Such signs of stress as elevated levels of the stress hormone cortisol and high blood pressure were significantly greater in those who did not get the vitamin supplement. Those who got vitamin C reported that they felt less stressed when they got the vitamin.

The researchers believe that vitamin C should be considered an essential part of stressmanagement.

Earlier studies showed that vitamin C abolished secretion of cortisol in animals that had been subjected to repeated stress. Cortisol is a hormone released by the adrenal glands in response to stress. Once it gets into the bloodstream, it is responsible for relaying the news of stress to all parts of the body and mind.

Cortisol is the hormone, for example, that triggers the "fight or flight" response to stress. That allows us to spring into action when we sense danger. But like many emergency-alert systems, the stress response comes at a considerable cost. Among other effects, frequent exposure to high levels of stress hormones exhausts the body's physical resources, impairs learning and memory, and makes people susceptible to depression.

In the animal studies, vitamin C fed to rats undergoing stress not only prevented the expected increase in cortisol levels, it prevented the animals from exhibiting the known signs of physical and emotional stress, including loss of body weight. Animals that did not receive vitamin C had three times the level of stress hormones.

The present RDA for vitamin C for adults is 60 milligrams—a far cry from the 1,000 mg found helpful in the stress study. But there's a growing belief that the RDA for vitamin C is vastly outdated. The current RDA was set decades ago and is based on the amount of the vitamin needed to ward off scurvy.

Current thinking looks at vitamin C from the opposite direction: The amount needed to promote health under varying environmental conditions. That appears to be a lot greater than the amount needed to prevent deficiencies.

There's also evidence suggesting that prehistoric humans consumed large amounts of vitamin C in a tropical diet rich in fresh fruits. If so, the physiological constitution we have inherited may require far larger daily doses of vitamin C than the current RDA, perhaps as high as 1,000 mg.

Vitamin C is present in fresh, uncooked fruits and vegetables, especially citrus fruits and red and green peppers. One eight-ounce glass of fresh orange juice provides 97 milligrams of the vitamin.

It's also found in papayas, cantaloupes, strawberries, broccoli, Brussels sprouts, tomatoes, asparagus and parsley. There's no vitamin C in animal food, and a small amount in raw fish.

An unstable substance, vitamin C is destroyed by cooking and exposure to light.

The most commonly consumed nutrient supplement, vitamin C comes in many formulations, but the best may be a time-released preparation that works over the course of a day, as the vitamin works rapidly and is short-acting. Alternatively, vitamin C supplements can be taken at intervals throughout the day.

Why do tigers climb trees?

Are you curious about tigers facts that why do tigers climb trees? Let's read and discover.

The tiger - a terrestrial cat:

Tigers are essentially terrestrial animals which confine climbing to their juvenile years:

They are very clumsy when aloft.

Despite their incredible muscle power tigers need to enter a tree at a run, being unable to simply pull themselves up in the manner used by leopards.

Also see elephant facts

They may get stuck in trees. Not being climbers by nature, it takes them time to learn the best way to descend is backwards.

Usually find that though claws make tree climbing possible, their angle also makes the descent an awkward job. 

Cubs:

Tiger cubs willingly climb trees for about the first sixteen months of life and young tigers have been sighted following langur monkeys up into the trees in an effort to secure a feed. But after this age their increasing weight makes both ascent and descent difficult, and few tree branches have the needed strength to hold their weight.

Adults:

Adults seldom climb, but are quite capable of doing so; they may do this if being chased by dogs or when after prey. There have been occasions of men climbing trees to escape an attacking tiger, only to be killed when the tiger followed them up. 

This does not mean tigers are willing or efficient climbers. On the contrary, they are not. The white Bengal and Amur tigers shown here are doing something quite unusual for tigers of their age.

Dragons are actually humans

We all know amazing animal facts that dragons apparently come from years and years ago. No-one is quite sure whether they exist or not, so the question is even if they did exist are they still alive now? They could come in any shape or form not neccesarily the way people describe them or imagine them, so it could be extremely difficult to identify them! 

Mythical fire-breathing winged dragons are fictional and have never existed. As fiction, stories about dragons have been told since 4000 B.C.E

Given the previous account on how dragons might be more intelligent than humans it is possible dragons have disguised themselves or transmuted themselves into a human form.

This implies that dragons could be all around us, you might have even met one but you never realized it ! It is even possible I’m a dragon and I don’t know it yet (well I was born in the year 1988 which is the year of the dragon in the Chinese calender).

In many ancient scriptures and tales there are accounts of Dragons taking on a human form, even of dragon being trapped inside a humans body. In some occult societies it is also thought that perhaps humans who reached the highest levels of magic, intelligence or spirituality were able to transform themselves into dragons.

Many cockroaches can fly

Somehow, I suspect that the only thing worse than roaches on the floor (or bed) are roaches flying around the room! But I still love to know some animal facts about them, such as whether or not cockroaches can fly

Many of the more than 3,500 cockroach species in the world can fly. The flying capabilities of cockroaches vary according to the particular species, and sometimes sexual category, to which they belong. In Canada, the German cockroach is the most important and prevalent cockroach species in the country. Depending on the region, other significant pest species present are the American, brown-banded, oriental, smoky-brown, and wood varieties of cockroach. Though both males and females of the German cockroach have wings, they do not fly except for short downward gliding. Meanwhile, both sexes of the smoky-brown species of cockroach are strong fliers. Amongst the brown-banded and wood cockroaches, only the males enjoy flying capabilities. Though not regarded as true flyers, both male and female American cockroaches maintain the ability to glide through the air. Both genders of the oriental cockroach lack the capacity to fly. The Canadian cockroach species capable of flying are generally only able to remain in the air for short amounts of time.

Despite possessing four wings, each flying cockroach uses just a single pair for air travel. Thick and protective, the front pair of wings displays the same coloration as the body of the cockroach and rests against the back of the insect when not in use. The back pair of wings remains hidden and protected beneath the front pair until the cockroach takes flight. When preparing to fly, cockroaches lift the front wings to expose the back wings. The insects keep the front wings lifted while flying and move through the air by using the back pair. In contrast to the front pair, the back wings of cockroaches that fly are membranous, thin and clear.

Interesting information about ducks.

Read on and enjoy a variety of interesting information about ducks.

1. All types of ducks are part of the bird family Anatidae, which also includes swans and geese. There are species of ducks found worldwide on every continent except Antarctica. Some duck species, such as the mallard, are found throughout the world, while others have very restricted ranges.
2. A baby duck is called a duckling, and an adult male is a drake. An adult female duck is called a hen or a duck, and a group of ducks can be called a raft, team or paddling. Generic terms like bird, chick and flock also apply to ducks.
3. All ducks have highly waterproof feathers as a result of an intricate feather structure and a waxy coating that is spread on each feather while preening. A duck's feathers are so waterproof that even when the duck dives underwater, its downy underlayer of feathers will stay completely dry. The uropygial gland produces that waxy oil that coats feathers so well, and many other birds also have the same gland.
4. Ducks are precocial, which means that ducklings are covered with down and able to walk and leave the nest just a few hours after hatching. This helps protect the young chicks from predators, since they do not need to stay in the vulnerable nest area for long.
5. A hen will lead her ducklings up to a half mile or more over land after hatching in order to find a suitable water source for swimming and feeding. As soon as a baby duck's down is dry after hatching, they will be able to swim.
6. Male ducks have an eclipse plumage similar to females that they wear after the breeding season for about a month as their new feathers grow. During that month, they are completely flightless and more vulnerable to predators. At this time, many male ducks stay in isolated, remote areas or flock together for protection in numbers.
7. Most duck species are monogamous for a breeding season but they do not mate for life. Instead, they will seek out new mates each year, seeking the healthiest, best mate who can help them pass on their genes to a new duckling generation.
8. When constructing her nest, a hen will line it with soft down feathers she plucks from her own breast. This gives the eggs the best possible cushioning and insulation. Other duck nesting material includes grasses, mud, twigs, leaves and other plant material.
9. Ducks are omnivorous, opportunistic eaters and will eat grass, aquatic plants, insects, seeds, fruit, fish, crustaceans and other types of food. Some ducks, such as mergansers, are more specialized in their dietary needs, but most ducks can adapt well to different food sources. This helps ensure they always have adequate food to eat.
10. A duck's bill is specialized to help it forage in mud and to strain food from the water. A hardnail at the tip of the bill helps with foraging, and the lamellae, a comb-like structure on the sides of the bill, strains small insects and crustaceans from water.
