The Great White Shark Beginning with the simplest one-celled organism, an extraordinary animal rose in the murky waters entitled to a non-comparable killing-eating machine. This organism has become nature’s most genuine and most successful creature that it has remained unchanged for over 250 million years. Nature finally invented the perfect king of the sea. This animal has given the sea it’s “living” adjective; in turn, it was entitled—the “great white shark.” The Great White Shark derived from a series of evolutionary advancements that took several billion years.
When little is known about a topic it is human nature to instinctively dislike that topic. Sadly, the topic is sharks, and for centuries people have surmised these creatures into a bleak, unforgiving category. The supposi...
Watching a movie where hundreds of swimmers on a beach are in a complete panic because of shark attacks makes a person scared to swim in an ocean, lake, or even a pond. Not only movies, but also documentaries of shark attacks stress how dangerous sharks are. In reality, are sharks really that dangerous or is it how they are portrayed? Stephen R. Palumbi who is a Professor of Biology at Stanford University and also the Director at the Hopkins Marine Station at Stanford wrote an article about other animals living in the ocean that are more dangerous to humans than sharks. In fact, he has written books about creatures in the water such as The Death and Life of Monterey Bay, and The Evolution Explosion. In addition, his son Anthony R. Palumbi is a novelist and a science writer that has written for Atlantic and other publications (Princeton University Press 1). Together they co- authored an article titled “Forget Shark Week: They aren’t the only fish in the sea” that was published the Los Angeles Times.
They are creatures that have no clue what we are and are afraid of us. Every year, thousands of more people are killed by other people than by sharks; thousand more people are killed in car accidents than by sharks, and more people are killed by lightning strikes than by sharks. Each year humans kill tens of thousands of sharks, yet, there are fewer than 100 shark attacks upon humans. For example, The Great White shark also known as the man-eater, has the greatest reputation for attacking humans. Recent studies of Great Whites show that they mainly feed on sea-mammals. Seen from below the surface a person swimming with a shark looks much like a seal, with arms and legs sticking out. The shark usually surprises its victim, being a person or seal, by one massive bite, and then retreats in order to allow the victim to die before digesting the food. For this reason, many humans survived the attack of a Great White shark if they are saved before being eaten. Not only getting out of the water and be safe, but the result of loss, blood or
Evidence on Prehistoric Sharks One of the previous papers in English class required the class to pick a paper to explore, this question will be concentrated on further in the synthesis essay. What evidence do scientist have to prove that prehistoric sharks existed? The reason behind picking this question wasn’t just to find proof that these monsters swam the seas, but to learn more about them from different resources. One of the resources that were used was a chapter in Angelo Mojetta’s book Sharks, called “ The Birth Of A Legend”. The other resource that was used for information was an article in Discovery Channels website called “ Prehistoric Sharks”.
Hypothesis: I will learn more about great white sharks Taxonomy The Great White Shark or Animalia Chordata Vertebrata Chrondrichthyes Elasmobranchii Lamniformes Lamnidae Carchardon C. carcharias is a marine predator. Carolus Linnaeus gave the shark it's first scientific name, Squalus carcharias in 1758. Later it was given its current name Carchardon C. carcharias by Sir Andrew Smith.
When the word Shark comes to mind most people think of a monster that feeds on humans and is an enemy of all living beings. Contrary to popular belief less than 10 percent of sharks are known to attack humans unprovoked. Sharks are classified under the class of Chondrichthyes, which is fish that have characteristics of a skeleton made of cartilage, jaws, paired fins, and paired nostrils. The superorders are divided into two groups, which are Batoidea that have rays and their relatives and Selachii, which are sharks. Scientists have found isolated spines, teeth, and scales that appeared 350 to 400 million years ago in the Devonian Period known as "Age of Fishes". Most modern sharks have evolved 100 million years ago when dinosaurs lived on earth. (Matthews, 1989) Sharks have been known to inhabit tropical and temperate seas as well as some cold and polar seas. Migration of sharks is poorly understood due to not all species migrating. And in the species that do migrate the distance may be short or long and is based on availability of the food and environmental cycles. One American biologist Eugenie Clark is the world leader in shark study, she was the first person to learn how sharks behaved in captivity and how well sharks had the ability to understand.
In recent years the ocean’s top predator is dancing on the brink of mass extinction mainly due to overfishing, finning practices, and weak or nonexistent regulation policies. While sharks kill only a few people per year, humans kill around 100 million sharks per year. In 2014 the International Union for Conservation of Nature released a report stating that more than 30 percent of the 64 species of sharks and rays are threatened and 24% are near-threatened with extinction. The iconic and feared great white is included in that 30
Sharks have existed for a very long time. They have existed for 400 million years. When people say dinosaurs have been around the longest, they are wrong. Sharks were around 200 million years before the dinosaurs. One of the earliest known sharks that were around at that time is the Cladoselache. The Cladoselache was around about 360 million years ago and was about two meters long (seven feet). My favorite shark is the Megalodon that roamed the waters about 200 million years ago. The megalodon was a massive shark that reached up to about 16 meters long (52 feet) and had a mouth th...
