Penguins My essay is about the history of penguins. Explorers believed that they were discovered around 1490. They were very impressed with the flightless bird, they studied them very carefully and documented everything they did. People still can’t agree who brought attention to the penguins some people say it was Vasco da Gama that showed proof. Other people say it was Ferdinand Megellan who found the penguins. The penguin’s ecosystem depends on the type of penguin some of the penguins can live in the coldest parts of the world ,but some can live near the very close to the equator where its warm. All penguins live within the Southern Hemisphere. Penguins can be located on every island in the southern hemisphere. Some penguins live on thick sheets of ice most of the …show more content…
The other penguins live on small sandy islands, but all penguins must live near a body of water to hunt for food. Their food consist of fish krill squid and crustaceans. Penguins mainly live along the coastal regions of South America, Africa, Australia, and New Zealand. People still don’t know everything about penguins but we start to learn more about them as we study them. There is some spots we don’t know if its 100% true or fake. This is way people argue so much about them because we still don’t know everything about them. In the mid 1800s people found fossils that looked like penguins. These fossils were studied by the top scientist around the world. The scientist are coming to a conclusion that penguins have been on earth for more than 60 million years.Scientist believe that penguins evolved from earlier birds in order to survive. They
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...
The population of the whooping cranes most definitely gets affected from precipitation, because the population gets affected negatively with high precipitation levels present, while positively with low precipitation levels. The population of the whooping cranes gets affected this way because if there were high precipitation levels for a year, the hatching success rate drastically decreases from the precipitation, who damages the eggs laid by the cranes. By either breaking the eggs, making the cranes not be present to incubate their eggs, or actually destroying the birds’ nests. Also, the high precipitation levels may even cause a few fatalities, which is a very serious problem involving this particular endangered species. While with low precipitation
Puffins live at sea while not mating or raising young. They glide across the water, swim on the surface of the ocean, and dive to depths of nearly 200 feet to get their food. Puffins commonly spend their entire winter at sea. Young puffins will spend two to three years out at sea before returning to land to mate.
who to this day is unknown. In this essay I am going to try and
These penguins lived after the Castastrophic event “Cretaceuous” that demolished the dinosaurs and many other species. Based on the DNA analyses and avaiable evidence of modern birds, we think the modern bird- lineages, including penguins, some how managed to survive through the Cretaceuous. Also it’s not shocking these fossils were found in New Zeland. The South Pacific and Southern oceans were free of predatory mammals, had abundant food, and had space for Penguins to breed. But the Southern Pacific is not the only area where Penguins inhabit. Many of modern penguins “Aptrenodytes” are located in the Antarctic. Recenelty it was discovered that there was a over looked feature on the surface of the fossil penguins flipper bone. These grooves were easily missed because the look was similar to tendons and muscles in the same area. It was discovered that these grooves were blood vessels that make up a counter current heat exchanger called “humeral arterial plexus” which allows penguins to limit the heat loss through the flippers. Also it helped Penguins maintain their core body temperature in cold water allowing them to survive long journeys in the cold waters. Although Penguins have luckily been able develop these traits to survive the dramatic shifts in climate, the world population can not mistake their success as resilience towards global warming.
all puffins mostly eat small sea animals, such as sand eels, herring, hake and capelin. Puffin diets vary from colony to colony because of the variety of fish around the breeding islands. During winter puffins may also eat crustaceans, but their preferred food is fish. For most of the year, Atlantic puffins live on the open ocean, with a range spanning from the eastern coast of Canada and the northern United States to the western coast of Europe and northern Russia. 60% of the world's puffins live near Iceland. Puffins are specially adapted to living on the open
On November 25, 2015 researchers living in Antarctica discovered the world’s largest penguin. Weighing ten thousand pounds and measuring about forty feet tall, this penguin is one of a kind. Before this discovery, the emperor penguin was the tallest and heaviest of all living penguin species, measuring about 4 feet and weighing about sixty pounds. Brian O’Connor, a zoologist who specializes in penguins, was amazed when the giant penguin emerged from the water. “The reason why I suspect nobody has ever discovered this penguin is because it spends almost twenty three hours a day underwater. To see it you must be outside at exactly 3:00am,” O’Connor proclaimed.
On our Earth, we are graced with many fantastic life forms. From those gliding through the heavenly skies, to those at the deepest depths of the oceans, there is a plethora of various species. A group of these, though, is like a diamond in the rough. While many people admire its beauty, they have yet to realize that it’s the love for them that is dwindling its population. Who are these magnificent creatures…none other then the penguins.
Peregrine falcons are found in every single part of the world except Antarctica. They were
Emperor penguin: It is one of the most well-known of flightless birds. It measures 115cm in height. It is found only in Antarctica, and feeds on fish, squid and krill.
Also, the Red Panda lives in colder climates and forest type biomes with bamboo. They live in temperate type biomes. They can be found is the delicious forests. Red Pandas love bamboo as their habitat/sh...
Little Blue Penguins are the smallest of the Penguin species, ranking in at around 13 inches tall and weigh the average of 3-5 pounds. The females appear smaller than the males, and are commonly darker in color. They have a white chin that carries all the way down to the rest of their body. (BioExpedition) These types of penguins are commonly found is areas of Southern Australia and New Zealand. Little Blue Penguins spend most of their lives in water, or shady and rocky environments. In these environments, that can live up to 6 years. Yet, if in an indoor facility they can live up to 20 years of age. Depending on the environment, many penguins take or find their feedings close to water. Their diet consists of fish, squid, and small sea animals. (BioExpedition) These animal begin mating around the age of 2 for a female, and around age 3 for a male. Their main way to recognize their mate, is with their very distinct mating call. The average amount of current Little Penguins is around 350,000 to 600,000, so there clearly is no worries about extinction anytime soon.
African penguins (Spheniscus demersus) have been on a downward decline. In 2010, African penguins were placed on the Red List by the International Union for Conservation of Nature (IUCN) signifying that they are endangered (Weller et al., 2014). African penguins are endemic to Southern Africa ranging from Namibia to South Africa (Weller et al., 2014). At the start of the twentieth century, African penguins constituted 570,000 breeding pairs, but at the end of the century the population decreased to 26,000 pairs, and finally, in the 1990s, there was a total of 18,000 adult penguins (Weller et al., 2014). Robben Island has the most inhabitants of African Penguins, starting with the initiation of nine breeding pairs in 1983, growing to 8,500 pairs
Another way, is the farther’s role is very important because farther penguins have to watch and keep the egg warm for four months. When the egg hatches the farther still has to keep the baby chick warm because it could die by coldness. Also, the farther has
The penguins’ habitat is ocean and rocky beaches. They live near the Cromwell Current to obtain food, because many fish swim on that current. They utilize the beaches, especially when they are nesting, and lay their eggs in holes or caves on the islands. Their diet consists of eating small fish that are found less than 30 meters deep in the water, because they don’t like to swim farther down than that (Animal Diversity Web).
