...Where did all the frogs go? Imagine years into the future from now, the newly born kids won’t even know what a frog even is, how sad would that be? No more familiar ribbit in the middle of the night. Amphibians are still very important to humans, to the ecosystem, and to predators. If the amphibians become extinct, they will be nothing but a memory. Frogs control pests like flies, mosquitoes, and other insects that have the capability of carrying a disease. If a mosquito is carrying a disease and bites a human, they could get malaria, which can cause death. Frogs decrease the chance for humans to get deadly diseases like that. As amphibians decrease, problems may increase. Loosing fifty percent of the amphibians would put them almost extinct; they are already on the endangered list, which wouldn’t be good if we lost even more of the population. Conversationalists think that because amphibians are small, they are not as important to focus on, but they are wrong. Like mentioned above, amphibians control the insect population. The loss of the amphibians will also cause their predators to die as well. Amphibians have been teaching us many things; they have been alive for 350 million years, surviving dinosaurs, meteors, and also humans. That is a long period of evolutionary success. They adapt to wide range of environments like deserts, forests, and ponds. They still teach us things today, like new medicines and cures that are used from the chemicals within...

...Blossom and Grueba Blossom and Grueba Deep in a swamp in a faraway town lied a lily pad community known for its marshy waters and remoteness, called Caymaris. Within its population there was a beautiful bullfrog named Blossom whom every one envied, for her long green legs, slender torso, and stunning emerald eyes, she was the talk of the bog. Other Inhabitants all prayed one day to be as alluring as her. Though Blossom was the fairest Bullfrog in her town, her sister Grueba did not have any of these attributes. She was polar opposite of Blossom, the kindest, hardworking Frog you could ever meet. She was always willing to lend a helping hand to anyone in need and volunteered to deliver food to all the hungry frogs of the town. Her torso was compact, round, and her eyes were off centered and as black as coal, and the legs she used to carry out her kindness were short and stumpy. Blossom never wanted any of the bayou to know that Grueba was her sister, for she thought she’d be ridiculed. Daily Blossom would go about her routine of awaking dressing prim and proper even styling her hair with a neatly done ponytail and a gigantic white bow adhering it together. While Grueba's hair was always a mess, and all the kids teased her and called her names. Every morning on their treacherous walk to school across the wetland and through the forest Blossom would be sure to stride far ahead of Grueba, to ensure that none of her classmates could see that they were sisters...

...teacher if Korea had any scary stories. “Kumiho, the Fox with the Nine-Tails”, he said. Of course my interest was peaked and so he said, “Kumiho is a nine-tailed fox who eats the hearts of humans in order to survive. She digs up graves sometimes to find hearts or attacks men.” He couldn’t tell me much more so I dug up some info. Unfortunately it all seems like the information is taken from a commentary on a book that holds the oral stories of Korea, Compendium of Korean Oral Literature. This is more or less taken from Wiki and all other sources that say the same basic information: A fox that lives a thousand years turns into a Kumiho, like its Japanese and Chinese counterparts (the kitsune and the huli jing). The current Japanese kitsune can sometimes be evil and sometimes good, but the Korean counterpart over the years has become a symbol of evil. Legends tell that while the Kumiho is capable transforming its appearance, there is still something persistently fox-like about it. In Transformation of the Kimono, a Kumiho transforms into an identical likeness of a bride at a wedding. Not even the bride’s mother can tell the difference. The Kumiho is only discovered when her clothes are removed. As the mythology of the Kumiho evolved it was later believed that a Kumiho had to consume human hearts in order to survive. Another version of the mythology, however, holds that with enough will a Kumiho could further ascend from its Yokwe state and become fully, permanently human and...

...only you can grab it. So, demand and work steadfastly. Before Michelangelo could make impossible possible in his painting of the ceiling of the Sistine Chapel, he had seen the unseen as a visualization in his mind. No one else saw the impossible dream until it was finished in 1512. My heart bleeds to say that with growing age comes constantly fading credence to dream. We seldom realize the incredible power that we have within us; the power to believe in ourselves & live our visions. Ironically we tend to focus more than needed on the criticism & pessimistic talks pelted on us making us believe in 1000 reasons to not set out fearlessly to achieve the dream that we have. I would like to share the story of 3 Frogs that I read a while back: There was once a bunch of 3 tiny frogs, who arranged a running competition. The goal was to reach the top of a very high tower. A big crowd gathered around the tower to see the race and cheer on the contestants. The race began… No one in the crowd really believed that the tiny frogs would reach the top of the tower. They shouted, “Oh, way too difficult!!! They will NEVER make it to the top” and “Not a chance. The tower is too high”. The tiny frogs began...

...Bizarre extinct frog brought back to life March 16, 2013, 10:55 am By environment reporter Sarah Clarke ABC Imagine a frog that can swallow its eggs, brood its young in its stomach and give birth through its mouth. The gastric brooding frog existed 30 years ago, but the extraordinary amphibian is now extinct. In a world first, a team of Australian scientists has taken the first major step in bringing it back to life. They have successfully reactivated its DNA and produced an embryo. Professor Mike Archer from the University of New South Wales is part of the team, which also includes researchers from the University of Newcastle. He says the amphibian was no ordinary frog. "In the stomach these eggs went on to develop into tadpoles and the tadpoles then went on to develop into little frogs," he told ABC radio's AM program. "And like any pregnant mum, when you have little babies rattling away in your stomach saying, 'let me out', she would then open her mouth and out would pop little frogs. "The first people that saw that were aghast. By the time anybody got excited about it, suddenly it was extinct. "So that's certainly one of the driving reasons why this would be a focal animal for seeing if we can de-extinct this amazing frog." That is exactly what a team of Australian scientists is doing. After locating a few carcases stored in a deep freezer, they have been able to recover tissue from the gastric brooding frog. Using a laboratory technique known as somatic cell nuclear transfer...

...Frogs vs. Toads Frogs and toads are “small, tailless animal” that belongs to the amphibian class. (Forester 536 & Gibbons 303) Everyone thinks that frogs and toads are different from one another but in fact “there is no clear distinction between” them (Burnie & Wilson 440). Most people find it very difficult to differentiate between a frog and a toad that they often mix them up. Their physical features are very much alike but they are different on the basis of anatomy and habitat. When you see a creature hopping along the side of the creek, can you tell if it’s a frog or a toad? Frogs are very unique because “some frogs have colorful markings” (Forester 536). While as toads are marked in a “drab shades of brown, tan, gray, or black that serves as camouflage” (Campbell 217). Besides their markings, “almost all frogs have the same basic body structure” (Forester 536). Frogs have “long, powerful hind legs, which they use for jumping” (Forester 536). “Frogs can leap long distances, but also use their limbs to swim, burrow, and even to glide from tree to tree” (Wake 337). Unlike frogs, toads “generally have squat bodies and short legs” (Campbell 217). They do not “jump” like frogs so they “make short hops or even walk” (Campbell 217). As opposed to skin, frogs have “thin, moist skin” (Forester 536) and “the skin of most toads is dry, rough, and covered with warts” (Gibbons 303). There is an advantage to a toad’s dry skin. It’s “warty skin allows it to inhabit drier regions than...

Emperor and king penguins, which live in Antarctica, warm their eggs by resting them on top of their feet. 8. Many snakes begin life in eggs too, but snake eggs are tough and leathery rather than hard and brittle. 9. A snake called the Indian rock python lays between 50 and 100 eggs at a time. 10. Since snakes are cold blooded, the mother rock python has to twitch her muscles to create heat. 11. During the two months it takes for the eggs to hatch, the mother python stays in one place and dose not even eat. 12. Frogs lay their eggs in jelly – like clumps along the edge of a pond. 13. Mother frogs do not take care of their eggs. 14. When a baby, or tadpole, hatches, it doesn’t look anything like an adult frog. 15. It has a tail, it has no legs or eyes, and it is completely helpless. 16. The tadpole grows legs, its tail begins to shrink, and it looks more and more like its parents. 17. Some baby animals do not hatch from eggs. 18. Mammals differ from other kinds of animals in other ways as well. 19.

...Compare and Contrast Frogs and Toads Frogs vs. Toads When you see a creature hopping a farseeing the side of the creek, bathroom you tell if its a frog frog or a toad? Many people rear end non tell the difference amidst the two. They ar similar in many ways. When flavor at the two, there are some differences in them. For instance the frog and toad both have bulging eye; however, the frogs eyes are s illuminely bigger than the toads. As you read on you will learn the differences and similarities between the frog and toad. There are 2000 known species of the frog compared to the 300 kinds of toads. A frog is a small, slim, four legged amphibian with smooth skin and foresighted powerful hind legs with webbed feet. The biggest frog is the Giant frog, sometimes called Goliath Frog, in West Africa. This Giant frog laughingstock grow up to a foot in length. The frog is green or brown skinned with dark markings, pointed head, long hind legs, and can get one to four inches in length. Some frogs have suckers on their feet which help them cling to tree diagram trunks as they climb, known as tree frogs. The toad on the other hand has dry, warty skin with non as powerful hind legs. Toads are also lucubrate compared to the slim frog. The toad will puff up with conduct at times. Toads walk slow and have shorter legs than the frog. Toads are light brown skinned with brown markings; dry skin, flabby and can get up to three inches in length. The frog belongs to the family Ranidae...

...Tikhomirova 1 Tatiana Tikhomirova Marcio Pre-Degree I 3 March 2014 Life Cycle of a Frog Despite the fact that the frog is a small animal, in terms of symbolism, it is of some interest. In ancient Egypt, because of its fertility, as well as a striking transformation from egg to a tadpole, and then in the quadruped animal, the frog was considered strange creature and was a symbol of emerging and ever-renewing life. Often, the ancient gods of care arising out of the mire, depicted with frog heads. Goddess of child-birth, who was a good helper of the popular religion, looked like a frog. (“Heqet”) This essay will describe frog’s transformation from egg to adult frog by three steps. First of all, frogs lay eggs. When multiple eggs stick together, they are collectively known as frogspawn. After fertilization, the innermost portion liquefies to allow free movement of the developing embryo. Most eggs are black or dark brown, and it has the advantage of absorbing heat from the sun, which holds the insulating capsule. Frogs lay a lot of eggs because there are many dangers between fertilization and grown frog. Those eggs that die turn white. Life starts right as the central yolk splits in two. It then divides into four, then eight, etc. Soon, the embryo starts to look more and more like a tadpole, getting longer and moving in egg. Usually, about 6-21 days after being fertilized, the egg will hatch. Most eggs are found in calm or static waters. When the rain comes along, after development...

It does not possess plentiful resources, finances or land mass. On a personal level I was once much like my country—insignificant and unnoticeable. I didn't play sports or embark on any adventures or challenges. I lived a boring life. If I were a flavor, I'd be vanilla. At the age __, things changed. A strong desire birthed within me to do something meaningful with my life. Dreams of attending university and plotting a career path dominated my thoughts. Looking around at my situation, I quickly realized that HOMETOWN was not the suitable place to achieve that dream. I was a frog in a well. I began to search for what I felt would be the ideal setting to study and to fulfill my goals. My quest soon culminated with (College). Here was an institution that had all the elements I was looking for as an international student preparing to make a global impact. New York is one of, if not the most, cosmopolitan cities in the world. It thrives with people of various nationalities and ethnicities. Even though the grand stage of __________ is a far cry from my home city, (COLLEGE)'s multicultural student body and international focus is exactly the environment where I'd feel at home. In addition, because of its focus, and international campuses, (COLLEGE)'s academic programs offer relevant, and first-hand perspectives on world...

So I end by telling you a little story. A group of frogs were traveling through the woods, and two of them fell into a deep pit. When the other frogs saw how deep the pit was, they told the two frogs that they were as good as dead. The two frogs ignored the comments and tried to jump up out of the pit with all their might. The other frogs kept telling them to stop, that they were as good as dead. Finally, one of the frogs took heed to what the other frogs were saying and gave up. He fell down and died.The other frog continued to jump as hard as he could. Once again, the crowd of frogs yelled at him to stop the pain and just...

...WHAT EFFECTS ARE CANE TOADS PRODUCING TOWARDS THE SUSTAINABILTY OF ECOSYSTEMS AND THE SURVIVAL OF NATIVE SPECIES Chelcy Jordan SUST 1000 October 10 2012 The introduction of invasive species can often lead to unpredictable alterations and a shift within natural ecosystems. Cane toads were originally introduced to Australia in 1935. They were brought into Australia to prey on specific pests that were attacking sugar cane plants. Cane toads are highly adaptive and can easily adjust to climate changes and feeding grounds. The growth of reproduction in cane toads has formed a species invasion on the habitat of native animals. Immense competition and a shift in ecosystems are a result of their significant growth rate. What effects are cane toads producing towards the sustainability of ecosystems and the survival of native species? Many animals, and plant species have been either finding new ways to adjust to changes caused by the introduction of cane toads. Cane toads have impacted natural ecosystems so drastically that they have left a strenuous effect on native species ability to maintain their own survival. This is crucial when looking at the effects cane toads have on sustaining plant and animal life within ecosystems. Dramatic changes in an ecosystem could potentially fail due to inadequate nutrients and energy distribution. It is important to examine ways in which cane toads affect ecosystems so environmentalists can predict potential negative shifts and try to develop...
