The Penguin (Sphenisciformes)
The penguin (Sphenisciformes) has been a fascination to numerous people including scientists and researchers alike. They have distinctive characteristics and an interesting classification system. Their eating habits, unique way of breeding and predators are just a way of everyday life that fascinates scientists and researchers. The species status still remains in danger and can hopefully be helped.
This unusual bird stands on short legs and walks with a clumsy waddle. These birds cannot fly which is how they got to be called Penguins, which means flightless. All species of penguins have short-bodies and necks. They also all have short thick feathers, which form a kind of waterproof coat. Most penguins’ feathers have feathers that are just white on the stomach and are black and blue on the back. Some have patches of brightly colored feathers on their necks. Theses birds keep warm from the harsh Antarctic conditions by thick layers of fat on their bodies. Their wings developed into flippers, which serve as paddles to help propel them in the water. They also have webbed feet which when combined with the flippers make them excellent swimmers and divers.
The species are divided into four groups for easy identification. The groups are as follows, I. “Large, with orange or yellow patches on the sides of the upper neck (Species 1-2). II. Medium-sized, crested with orange or yellow lines on each side of the crown above the eyes (Species 3-8). III. Medium-sized, with no crest or yellow colour on the head, but usually with stripes of white or black on the head or breast (Species 9-14). IV. Small, with out crest or yellow colouring on heads (Species 15-17)” (Alexander 148). An example of each is as follows: Group I, the Emperor penguin. Group II, the Royal penguin. Group III, Adelie penguin and Group IV, the Whit-filppered penguin.
The Emperor penguin is the largest penguin with the most southern range. The top of the head, chin, cheeks and throat are black, with a broad orange semicircle patch on each side of the upper neck. They have a long bill, which curves down, and a short tail composed of 20 feathers. The Royal penguin’s neck, chin, and throat are white. They have a broad orange band across the forehead and a short tail consisting of 14 feathers.
Today we will be taking about the Duck Billed Platypus, we will be seeing that makes them different. The first thing we will start out with is their appearance. The Platypus has brown waterproof fur and a flat tail like a beaver they also have a bill and webbed feet like a duck. They next thing I will talk about a Platypus diet. A Platypus mainly eat insects and larvae, shellfish, and worms but because Platypus have no teeth they use gravel they scoop up to break up there food. Platypus are also Carnivore meaning they only eat meat or flesh. Next we will talk about the Platypus defenses. When swimming the Platypus have folds of skin covering their eyes and ears to prevent water from entering, and the nostrils close with a watertight

The platypus is a very unique and interesting mammal. It is only one of five species
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.
paragraph 1:platypus skin color is brown,it has a larger nose.The female platypus mass is 1.5 to 3.5 and the male platypus is 2.2 to 5.3.They have feet like the ducks but four of them.
Vegetarians don’t cut out animal products all together therefore their diet, although not containing meat or flesh of any kind is still more diverse and a better, healthier choice than that of a vegan while still holding on so some of their ethical concerns. Vegans do miss out on many nutrients that are ob...
The large ground finches have a higher curve while the medium ground finches have a smaller head and a tiny beak. The place in which the finches live is what changes their appearances and also the weather helps decide the appearance of these finches.
Deforestation is a widely used term, but one with different meanings. Disturbance deforestation refers to all man made disturbances that alter a forest, these are the most common. This argumentative essay discusses the positive and negative aspects of deforestation. In the first part of the essay the pro arguments of deforestation will be discussed. For example, the issue of Global population and how forests are being used, land use and the ways forests contribute, wood use, forest growth, destruction and the reasons for cutting down the trees. The second half of the essay will cover the issues that are harmful to the environment because of deforestation. Many environmental issues take place everyday; a big question that arises, is if the global economy will ever finds middle on the issue of forest thinning. If deforestation was used only in the most crucial of times, the world might become a better place.
The Overpopulation of the Snow Goose in North America Abstract The purpose of this paper is to explore available research on the overpopulation of the Snow Goose on the North American continent. The snow goose has been rising in population since the middle of the century and has been escalating so much it is destroying their natural habitat. Wildlife managers have just recently begun to implement strategies to combat this problem. Mainly through the use of hunters, the managers are trying to curb the population growth. Introduction There are three main species of Snow Goose of primary concern.
The earliest archeological data we have that suggest a voluntary partial vegetarian diet is the Old kingdom of Egypt. There are hieroglyphic inscriptions, which suggest the avoidance of eating some animals. The priests avoided eating pig for its lack of cleanliness, and cow for their belief that it was sacred mainly did this. This is believed to been practiced as early as 3000 BC. There are few historical sources on the practice of abstaining from meat in ancient Egypt, but we do know it directly influenced the beliefs held across the Mediterranean in Greece.

The single biggest direct cause of tropical deforestation is conversion to cropland and pasture, mostly for subsistence, which is growing crops or raising livestock to meet daily needs. The conversion to agricultural land usually results from multiple direct factors. For example, countries build roads into remote areas to improve overland transportation of goods. The road development itself causes a limited amount of deforestation. But roads also provide entry to previously inaccessible—and often unclaimed—land. Logging, both legal and illegal, often follows road expansion (and in some cases is the reason for the road expansion). When loggers have harvested an area’s valuable timber, they move on. The roads and the logged areas become a magnet for settlers—farmers and ranchers who slash and burn the remaining forest for cropland or cattle pasture, completing the deforestation chain that began with road building. In other cases, forests that have been degraded by logging become fire-prone and are eventually deforested by repeated accidental fires from adjacent farms or pastures.
The hornbill has a casque on top of its head, giving it its name. The casque is made of the same material of the bill itself. It is a black bird with a white stomach. The bottom of the wings are white as well. It has white around its eyes. The bird is typically 55-60 cm long. The male is 680-907 g in weight. Those are just a few of the characteristics of the hornbill.
Thousands of different types of birds roam the Earth as we know it today, so let’s begin consider the origin of these beings. How had these creatures come to be? What was their original form? The evolution of birds has only recently begun to explode with new information within the last decade (Savile, 1957, p. 212). Birds are unique creatures and inhabit a wide variety of locations, but constant among them is the fact that they came from Archaeopteryx. Over time, three key changes have developed with the bird’s anatomy that makes it a paradigm of evolution.
