Myopic little men in tuxedos, or highly efficient land/water animals? Recent research indicates there's more to penguins than meets the eye. If you've every wondered what it would be like to be able to see as clearly under water as you can on land, just ask the nearest penguin.Most aquatic animals are short-sighted on land. Most terrestrial animals (and that includes us) are far-sighted under water. But researchers have discovered that penguins can apparently see equally well in both environments, because of the unique structure of their eyes. Penguins have to be able to see well under water because their diet consists mainly of plankton, molluscs, crustaceans, and the inevitable fish. Through a special slowing-down of their heart rate they're able, like many other diving animals, to stay submerged long enough to search out and chase whatever catches their fancy. On dry land, it's a different story-or has been up to now.
Waddling along on their flat little feet, eyes fixed intently on the ground, penguins appear myopic, inefficient and generally out of place. In fact the reverse is true. During a recent stay on the
Falkland Islands, a Canadian researcher discovered that penguins are able to recognize individuals and navigate the rocky terrain on which they live quite well. Long of body and short of leg, they probably poke their heads forward as an aid to balance. And as for looking at the ground, they're merely-like us-keeping an eye on where they're going. The human eye is adapted for aerial vision, which is why scuba divers-or even you and
I in the local swimming pool-must wear goggles or a face mask to re-introduce air in front of our eyes in order to see clearly. Among vertebrates in general, the bird eye is frequently described as the most efficient. Its superior quality, combined with the fact that a large number of birds-cormorants, pelicans, seagulls, even ducks, as well as penguins-get their food from water, obviously
In 1782, the bald eagle was elected as the national symbol of the United States of America, yet by the early 1960’s, it was nearly extinct in the Continental United States. A combination of many dangers, with the main danger being the pesticide DDT, the bald eagle was on the verge of extinction. Yet, through conservation measure applied by the United States government the bald eagle cam back from the brink and was taken off of the endangered species list in 2007.
Like I said moments ago, the penguin is known to be witty, meticulous, inscrutable and they of course live on ice! First of all, I can be witty if I want to, and I spend half of my time on the ice. By that, I mean at the arena playing or practicing ringette. Ringette is a part of me and it always will be. I love the sound of my skate edge cutting into the ice. In addition to that, I love the way snow sprays off my skate when I make a quick stop as well. These are just some of the way that I can relate to a penguin. In conclusion to this paragraph, I am most like a penguin because I often enjoy the cold
The wolverine (Gulo gulo) which means glutton is a member of the mustelid’s. Wolverines can be found in remote reaches of Northern boreal forests, the subarctic and the alpine tundra. There are millions of wolverines throughout the world making them least concerned on their conservation status. The biome they live in is the coniferous forest. They choose to live in this biome because of the warm summers and cool winters with adequate rainfall. The wolverine is known to be a powerful, aggressive and very territorial. They are also very efficient scavengers with strong teeth and muscles that allow them to rip through frozen bone and flesh. Wolverines live in dens around the world from the US to Europe, Russia, and Siberia and mainly in Northern Canada.
John Steinbeck uses his unique literary style to write the short story “The Chrysanthemums,” where he brings his readers to a society of inequality amongst the genders. “The Chrysanthemums” depicts the challenges of Elisa Allen, a thirty five-year-old woman who is expected to be a traditional housewife. Her ongoing transformation throughout the story portrays the life of a woman trying to gain meaning in her dull life during the 1930’s. John Steinbeck's, “The Chrysanthemums,” shows the true feelings of the protagonist, Elisa Allen, through the use of femininity, self-awareness, and weakness.
After watching March of the Penguins I was browsing the internet while I was trying to figure out which direction to take the essay in, because there were too many possibilities for the topic. Soon I found myself watching Monty Python, when the perfect sketch to start this paper on comes on. A newspaper reporter comes on saying "Penguins, yes penguins what relevance do penguins have with the furtherance of medical science? Well strangely enough quite a lot" He moves into a joke about research not being accidental. Then he picks up of the penguins "Nevertheless scientists believe that these penguins, these comic flightless web-footed little b@$#ards are un-wittingly helping man to fathom the uncharted depths of the human mind." The news cast flips to the scientist who introduces himself then states "...having been working on the theory postulated by the late Dr. Kramer that the penguin in intrinsically more intelligent than the human being." From there a multitude of science spoofs lead to the confirmation of this theory of penguins being smarter, even though it is clearly pointed out that the penguin's brain is smaller than of a human being. This causes the penguins to rise up and take over the roles of humans. After careful consideration I decided to discuss this clip as there really is no better way to introduce how animals are used in film as entertainment. Whether it is a crazy Monty Python sketch or the heartwarming love story that is March of the Penguins both were created for many reasons, but the most influential was the desire to earn money. For now just keep Monty Python on the back burner it will have significance later, lets shift to dealing with the questions being posed about March of the Penguins. How did March o...
There are at least 145 living species of the suborder Anthropoidea . Over 90% of them are monkeys. The remaining species are apes and humans. The anthropoids (members of the suborder Anthropoidea) have been the most successful primates in populating the earth. They are generally larger, more intelligent, and have more highly developed eyes than the prosimians.
Globalization is _______ and thus has the potential to do a lot good and to bring prosperity to many people around the globe. However, its management brings about social fragmentation that leads to violence and corruption, and creates opportunities for transnational criminal organizations to arise and to remain in business. An example of such organization is the Pink Panthers who according to the Interpol is a group behind armed robberies in East Europe, the Middle East, Asia, and the United States. They are believed to have “carried out robberies worth in excess of EUR 330 million since 1999. Hundreds of suspects are linked to more than 340 robberies in 35 countries” (Interpol). In 2013 for instance, in Cannes, France, the Pink Panthers in less than 60 seconds stole $138 million worth of jewels. Within a few days some of the jewels were recovered in New York. This criminal organization is made up of jewelry thieves from the former Yugoslavia, which began due to the extreme violence and political instability during the Balkan wars of the 1990s.
Porcupines African Crested Porcupines Order: rodent. A porcupine's habitat and range: forests, deserts, and grasslands of North and South America, Africa, Europe, and Asia. Porcupines can weigh from 2 to 60 pounds depending on the species. A prickly coat of needle-sharp quills is the porcupine's best defense. Ordinarily the quills lay flat. But if an enemy approaches the porcupine will raise the quills and spread them, usually deterring the enemy. If the animal is not deterred the quills may lodge in the enemy's flesh when the porcupine brushes against the animal. New quills grow in to relace the lost ones. The porcupine cannot throw its quills. There are two groups of porcupines. They differ in habits and appearance. The porcupines of the Americas also climb trees. Some have been seen using their tails to hold on to branches. In the winter the North American porcupine eats evergreen needles and bark. When spring arrives they feed on leaves, buds, stems, and fruit. Depending on the species, the gestation period is from 2 to 7 months, bearing 1 to 4 young. The life span of captive porcupines can be as much as 20 years. The Future of the Porcupine They are nearsighted, have a deep red shine to their eyes, and four toes on each front foot and five toes on each hind foot. Porkies are the second-largest rodent in Wisconsin after the North American beaver. They can weigh 30 pounds or more in summer but their weight drops dramatically during the lean months of winter. Porcupines live in the northern two-thirds of the state in a territory that extends in a V-shape from about the Ellsworth area in Pierce County down to Wisconsin Dells and back up toward Green Bay. Porcupines, like most rodents, are vegetarians. Their winter diet consists of conifer needles, buds and the bark of pines, hemlock, maples and birch. How these critters survive on foods with a protein content of only two to three percent is truly amazing. Porcupines are sloppy eaters who drop a lot of greenery that provides a welcome snack for white-tailed deer during deep snows. If you spot a small pile of freshly-snipped branches on a winter walk, it's likely porcupines are nearby. Their winter dens are easy to find -- just follow your eyes and nose. Porcupines winter in caves and hollow logs. They travel the same paths every day.
Alnut Kelber, Anna Balkenius, and Eric. J. Warrant studied the night-time vision of a nocturnal hawkmoth, Deilephila elpenor. They wanted to know if the hawkmoths can truly see colors at night, or if they are using other means to find the right kind of flowers to feed from. For example, humans cannot see colors at night and therefore have a harder time differentiating between objects using vision alone. However, a person could find food in a dark room using his or her other senses, such as smell or taste, or could rely on colorless vision to choose food based on its shape. The scientists tested a series of experiments to show that hawkmoths use color-vision at night, as opposed to reverting to their other senses like humans do.
Polar bears prefer to live in extremely cold artic climates. They live only in the Northern Hemisphere, on the arctic ice cap, and they spend most of their time on coastal areas. Polar bears are widely spread in Canada, extending from the northern arctic islands south to the Hudson Bay area. They are also found in Greenland, on islands off the shore of Norway, on the northern coast of the former Soviet Union, and on the northern and northwestern coasts of Alaska in the United States.
The Orca is irrefutably one of the most fascinating animals in the ocean. Killer whales, or Orca, are aquatic mammals which live in almost every ocean on Earth. Their black and white color pattern makes them one of the most easily recognized animals on Earth, and their intelligence and strength makes them apex predators. Though the killer whale sounds like an aggressive animal, Orcas are very social and are very sensible in what they kill.
