Megalodon is a prehistoric shark from 23-2.6 million years ago. It is a pretty well known fact that there is an argument over whether or not a megalodon lives in the mariana trench. Research shown in this paper will prove that megalodon is extinct and does not live in the mariana trench and why. Some people think megalodon is alive and in the mariana trench. Why because their reasoning is that if the megalodon had to get food it could eat things such as giant squid, some whales and some undiscovered animal of the deep parts of the mariana trench.Why that they say it can be undetected, because such animals such as the megamouth have not been discovered until recently and they are pretty huge, so they that is why they say it can be not be
As Stephen Covey once declared, “Just as we develop our physical muscles through overcoming opposition- such as lifting weight- we develop our character muscles by overcoming challenges and adversity.” This may seem like no sweat, but in reality it is laborious to do. Nevertheless, there are many people who embody this quote in our everyday lives and even in literature. The short story The Truth About Sharks by Joan Bauer, depicts such a person. In this anecdote, the experience that the protagonist, Beth faced, taught her to stand up for herself and therefore feel empowered. She went from a sullen teenager who was unable to stand up to her uncle and one who felt insecure in the shadow of her cousin, to someone with the confidence to rise above. The Truth About Sharks portrays a vital change that happened to Beth as a result of her being falsely accused of shoplifting and the challenges she faced to clear her name. This article renders a dynamic change that occurred in the main character, Beth who demonstrated the theme stand up for what you think is right.
Mojetta and Discovery Channel had a lot of strong data on prehistoric sharks. The information that was presented in their text gives people knowledge of prehistoric sharks characteristics, time frame they lived in and the remains of these creatures. These bits of information might raise more questions for people about evolution. There have been many different species of prehistoric sharks discovered throughout the years.
The film Sharkwater is a documentary directed and produced by Rob Stewart. Rob is an underwater photographer and a biologist that has a fascination with sharks, and their behavioral aspects. His way of studying these creatures he is able to learn about life and how to survive on this earth. This film showed the characteristics of reflexive documentary, this is because of the attention drawn into the sharks, their behaviors, and how we are affecting them. A statement that really stuck the documentary is people are taught their whole entire lives that sharks are dangerous but when you finally see it underwater your whole life can change in a flash. Rob made a very valid point as well, which is believed to be his thesis statement.
In my research, the Oceans of Kansas organization for Paleontology has given me more than enough to focus on when depicting out how to correlate our modern logic about how Kansas is mostly a wasteland to when it used to be an ocean with striving life within. The sharks that have been recently discovered are increasing not only in size, but by type. Mike Everhart, lead Paleontologist of this organization, in April 2002 discovered an extremely large shark called the Cretoxyrhina Mantelli "Ginsu Shark". “A large lamniform shark found worldwide from Turonian into Campanian time during the Late Cretaceous. Much the same size as a modern Great White (but not closely related), the Ginsu shark reached lengths of more than 6 meters before becoming extinct about 82 million years ago.
The bull shark may be responsible for many shark attacks in the world but I believe that we have no right to kill them. Sharks are very important to animals food cycles and if the food cycles get messed up it can greatly effect the world. In fact, the bull shark is more vulnerable to human impact due to their ability to live in fresh and salt water but many sharks that are killed are for either shark fin soup or their liver oil. The sharks liver oil has many uses now but it started as a machine lubricant. Another way that sharks die is by recreational fishing. The sharks can get caught up in the fishermen's nets and eventually suffocate and die. As an environmental community, I feel like we need to inform people about shark habits and how to keep sharks safe. The water is their home and we are
This image is what a majority of people believe to be the shark. They believe it to be the bloodthirsty sea monster that appears in countless works of literature and films, but science says otherwise. The classic picture painted by the minds of sailors returning from years at sea come from imagination and sharks’ violent methods of hunting and mating. Sharks fear humans as much as humans fear sharks, and most sharks, particularly the “man-eating” great whites, only bite humans because they mistake surfers for seals. In earlier times, the ocean was a source of mystery and adventur...
The Great Shark debate – to cull or not to cull, has been at the forefront of the minds of conservationists, as well as the general population for many decades now. The opinions of everyone are divided, according to their personal experiences, and views on what is right and wrong for the environment.
Image sitting on the beach one July morning. The sun is beaming down and decide to go for a swim. As you approach the water, you see a whale unusually close. You begin to get nervous as it continues to approach the shore. However, you aren’t worried because you know that they are confined to the sea. As the whale comes near you can see it clearly. Just as you think that it will turn around, the whale walks out of the ocean!
First, the period depicted in this tale takes place about 20,000 years ago. A time when dinosaurs no longer roamed the earth but megafauna, large vertebrates, was abundant. Vertebrates in this group inc...
The origin of modern day whales, a mystery that has puzzled paleontologists for years, may have just been solved with the discovery of an ankle bone. This discovery might sound simple and unimportant, but the bones of these ancient animals hold many unanswered questions and provide solid proof of origin and behavior. The relationship between whales and other animals has proven to be difficult because whales are warm-blooded, like humans, yet they live in the sea. The fact that they are warm-blooded suggests that they are related to some type of land animal. However, the questions of exactly which animal, and how whales evolved from land to water, have remained unanswered until now.
Have you ever met a prodigious manatee or dugong? Georg Wilhelm Steller has, this marine mammal was called Steller’s sea cow. This prehistoric animal was discovered in 1741 and disappeared from the face of the earth in 1768. Steller’s sea cow is an important animal to learn about because of the way they looked, the time period they lived in, and the surprising facts about them.
“Beneath its glassy surface a world of gliding monsters.” In the movie Deep Blue Sea several witnesses of a helicopter crash on Aquatica must elude enhanced Mako Sharks and the ocean itself in order to make it to the surface alive. Throughout the movie, the characters continually evade explosions and shark attacks during their hunt to reach the surface. The ocean in the Deep Blue Sea not only plays an obstacle and impending doom but also a goal and advantage depending on the perspective.
The Humpback Whale, Megaptera novaeangliae, is part of the marine mammals group. They are found in oceans all over the world, they live in open waters. Even though they are mammals, they do not live on land (Monterey Bay Aquarium). Humpback whales are known for their magical song that can travel great distances. These gentle giants are omnivores, their main diet is krill. They are mostly found near coastlines feeding on tiny shrimp-like krill, plankton and small fish. Humpbacks migrate annually from summer feeding grounds near the poles to warmer winter breeding water closer to the Equator. Humpback whales are powerful swimmers, and they use their massive tail fin, called a fluke to propel themselves through or even out of the water! Mothers and their young swim close together, often touching one another with their flippers with what appears to be gestures of affection. Even though it takes more than one year for a humpback whale to grow fully, mother whales leave them after one year (National Geographic).
The article, An Ocean Mystery in the Trillions by William J. Broadjune is about information regarding a family of fish named bristle mouths. Divers have discovered the existence of this family of fish as early as 1872, living in deep ocean depths during a sea expedition. The author discusses their unique characteristics such as its ability to change its gender, “bristle like teeth”, and a strategy called counter-illumination that they use to protect themselves from predators. All the fish’s features are essential to their survival from both predators and the environment. Furthermore, there is a large amount of evidence supporting the fact that it is the most found vertebrate on the planet with a possible population of thousands of trillions. Many sea expeditions over the years have been able to confirm their large population. However, questions were raised when scientists solved the mystery of the Deep Scattering Layer during the Cold War for military purposes. The layer was composed of a large amount of sea creatures that caused sonars to determine the area as the seabed. When scientists looked further into what type of sea
