Essay on The Sharks Potential in the Cure for Human Cancer

Sharks have been creatures that can date back to over 450 billion years, and have survived through all disaster and still live on Earth today. This is a great feat for anything to stay in existence for that amount of time, and hopefully sharks can continue to live on this Earth and not go extinct. There are hundreds if not thousands of species of shark from when they first swam Earth’s oceans to when they continue to swim the same oceans. The study of sharks is a very interesting and extraordinary topic, being able to put together images of what sharks used to look like compared to sharks now is just amazing. In this vast amount of time sharks have spent on this Earth there has been many things that has changed, through evolution and adaptation. Through research and personal opinion I plan to show how sharks have evolved, what has changed through evolution and the history of

They do this because of the limited amount of space on the ship. Shark liver oil is used as a source of vitamin A, and some people believe that the cartilage and liver of a shark are extremely beneficial to human health. In earlier days the sharks' teeth-like scales on their skin was used as fine sandpaper, and when the scales were removed from their skin it made fine leather. This leather was used for making shoes, belts and handbags. Each year thousands of sharks are killed unintentionally due to nets used to catch different types of fish, and sometimes humans kill sharks because they fear them (Springer and Gold, 1989). All of these activities have resulted in many shark species being in danger of extinction.

This, according to the clonal selection theory, the immune system functions on the “ready-made” rather than the “made-to-measure” principle. The question of how an animal makes so many different antibodies there for become a problem of genetics rather than one of protein chemistry” (Bowden 1006). This means that genetics determine how well the immune system works and this the key to figuring out a way to boost the immune system to help fight of infections and diseases before they even begin to weaken and infect the whole body. If someone decided they wanted to be immune to a snake bite or HIV the only thing that would have to be done is find one person just one that is immune and clone that person gene and add it to the other person who also wants to be immune to a certain disease, physical or chemical problem. “Scientist have grown replacement organs for sheep, rats and rabbits using the animal's own cells and alb molds to help the tissue take shape a technique that could be used someday to make spare parts for

The things that sharks are being killed for is sickening. So far, humans have decimated about 90 percent of the world’s shark populations for the sake of shark tooth jewelry and jaws that tourists buy in massive quantities, sharkskin accessories, phony medicines made from their cartilage, and a huge range of cosmetics, deodorants, moisturizers, sun tan lotions, and lip balms that use shark liver oil as a base because it makes our skin soft. (Check the ingredients of these items before you buy. If they contain “squalene” or “squalane,” leave them on the shelf.) (M. R., Ph. (2015, February 08). The Most Misunderstood Shark Fact Of All Time. From

We should protect the sharks, because lots of them are dying, and most sharks are harmless, not dangerous so why be afraid of the sharks?

This organism causes the sharks to go blind. Luckily Greenland sharks are mainly scaevngers and heavily rely on their heighted sense of smell.

People visceral when they see a shark and they try to capture and kill it. Only some people want to protect sharks. Sharks help by keeping the fish population down First, we can protect sharks by doing little things such as stop finning sharks, picking up our trash. Next people destroy environments by oil spills. Not picking up trash. Last if people don’t stop finning sharks and not throwing their trash away our environment will smell bad and we will have no sharks left.

The Great White Shark derived from a series of evolutionary advancements that took several billion years. It began with the derivation of the vertebrates—the Phylum

Whether it is the fining for fin soup or the desire to have a large shark jaw, sharks are being killed at alarming rates.

This article talks about what sharks does in order to survive and what are they capable of doing. According to the article, sharks do not sleep; but rather, they have rest periods throughout their day. Sharks are capable of hearing anything below 1000 Hertz and can also swim up to 20 mph. Sharks skeleton is made up of cartilage rather than bone. According to the article, cartilages are lighter than bones. What keep them from floating are their large livers. Sharks can gather and keep the air into their stomach to keep them from floating.

Over the past 100 years sharks attack numbers, though rare, have been increasing. Ironically two of the most recent attacks have happened this month, which is the 40 year anniversary of the movie Jaws. these two attacks happened at Oak Island in North Carolina. The two attacks were at different times, only by hours, but on the same beach. It’s suspected that either a tiger or bull shark had attacked these two teen girls, but usually great white, lemon, spinner sharks are to blame for human attacks. Attacks this year had also been performed by a nurse and mako shark. Most attacks are categorized as “provoked attacks.” This is like a shark getting a shark bite during spearfishing, shark catching, or even releasing it from a line. Sharks accidentally

To understand why we need sharks, we have to first look at what an ecosystem is. An ecosystem, as described by the Mirriam Webster Dictionary, is “a system, or a group of interconnected elements, formed by the interaction of a community of organisms with

Sharks have been known to have high amounts of proteins in their meat and they have high commercial and recreational value. For thousands of years this cruel sport has been occurring. Each year humans kill 100 million sharks, The act of shark finning can be described as very cruel; fishers catch a shark, cut off its fins, and throws the shark back in the ocean to die. There are many reasons why people around the world have made it a job or hobby to catch sharks these include; shark finning, high price for shark meat, recreational, food, a “miracle” soup in Asia, obtaining their cartilage, and their oils and skin. This activity has caused a high depletion rate in the shark population, and sharks are apex predators. Apex predators are very necessary in the growth and survival of an ecosystem. If we kill a lot of sharks we then create an imbalance of animals that can cause several problems for the ocean. We need to make a stop worldwide and have significant changes to the consequences for this cruel

Sharks have streamlined bodies and a special set of organs which makes sharks special from other fish. When sharks attack, they have a special lining that moves over the eye to protect the eye from debris in the water. This lining, however, renders the sharks blind sometimes missing their prey, this is why they usually come out of the water or “breach” into the air during an attack. They are not really good swimmers, but sharks can swim very fast,

Sharks have existed on this earth for over 400 million years, and for the most part have been one of the only species in earth’s history that has not been changed dramatically as a result of evolution (http://www.nutritionwarehouse.com/Shark.Cartilage.html). Furthermore, in recent times since the onslaught of the industrial revolution, numerous pollutants and toxins have been introduced into the earth’s oceans, forests, and atmosphere resulting in cancerous development in nearly all forms of life. Incredibly, however, the amazing living machine known as the shark has survived literally unchanged and has rarely developed cancer despite the fact that almost all other creatures of land and sea get cancer
