However, the gill arches during the embryonic stage create similar structure in use, not appearance. The first gill arch creates “the trigeminal nerve in both humans and sharks” (Shubin 91). The cells of the second gill arch gives us cartilage and muscle that helps the creation of the stapes, as well as another bone, the hyoid, that assists in swallowing. In a shark, the same arch “helps with jaw production” that compares to hyoid (Shubin 92). In the third and fourth gill arch, for humans it produces structures necessary for speech and swallow and for sharks it includes parts of tissues that support the gills. Sharks and humans have gill arches in the embryonic stage, but unlike the statement proposes, they do develop into related structures in each…

We are all sharks underneath the skin, to put it more precisely we are all modified sharks, said fossil expert Neil Shubin. As Shubin makes it clear, evolution does not proceed in mighty anatomical jumps but to the process of gradual changes, transforming a gene, cell, or bone for a new purpose. In this way new species are eventually created. Albeit, a new species that still carries traces of it's evolutionary predecessors, an inner connection between fish and humans. You can see these biological stigmata today, says Shubin. Our hands resemble fossil fins, our heads are organized like those of long extinct jawless fish, and major parts of our genomes still function like those of worms and bacteria. Hypothetically we are all "shark siblings".…

The vampire fish. That is what the Sea lamprey was nicknamed when discovered in 1835. First spotted in Lake Ontario, researchers were horrified to learn that the Sea lamprey feeds on blood. These parasitic fish latch on to their victims and siphon their blood and other body fluids, sucking them completely dry. What separates the Sea lamprey from other fish, other than their horrifying blood fetish, is their unique body structure. These fish do not have jaws or any other bone structure in their anatomy. Instead of the norm they possess a skeleton that is made out of cartilage. With a unique body set up, comes a unique mouth. It is described to be a large hole filled with sharp, pointy teeth. And this teeth frame a just as deadly tongue.…

The sand shark is very important to my tribe, and I shall tell you why. Once, a very long time ago, a group of hunters were looking for animals for food and supplies. The eldest, and wisest, said “We must continue hunting! Do not lose hope!” Suddenly a squirrel scampered across a cedar branch. The youngest was quick, he raised his bow, arrow drawn, and shot. The squirrel was too quick, the arrow missed. Several days later, hunger spread throughout the village. The three hunters had failed to collect enough food for the winter. Many died, some went mad with starvation. One day in winter, the hunters had no choice but to hunt. After several hours, they noticed that one spot of water had not frozen. The hunters made the decision to go fishing.…
Have you ever been swimming at the beach and thought that perhaps you had seen a shark? Sharks have become a common fear for most humans since the movie Jaws first appeared on the screen in 1975. Prior to that movie most people never gave a thought about sharks being a danger to humans. Actually we are more of a threat to them than they are to us. Some shark conservationists have pointed out that hundreds more people are killed every year in furniture related accidents than by sharks. Attacks on humans could be termed mistaken identity.…
I chose “The Shark And The Goldfish” by Jon Gordon for my book report. This book is about positive ways to thrive during waves of change and follows a goldfish named Gordy who washes out into the ocean. Gordy has always been taken care of and fed daily, but doesn’t know how to act or get food when he is in the ocean. He meets a nice shark named Sammy who teaches him how to find food and take care of himself. The story is a lesson for how you never know what life is going to throw at you and when a new challenge or change comes your way, it is up to you to embrace the change and learn to grow instead of viewing the change as a negative. The lingering question in the beginning of the story is are you a shark or a goldfish and how you can learn to become a shark if you tend to have more goldfish like tendencies.…
Great white sharks are known as the most dangerous of the shark species because of their sheer size and their quick mind that make them the ultimate predator. A comparison can be seen in Figure 1, where the great white shark is seen next to a human, this image is showing the sizing difference between the two species. The shark is so captivating that there is an entire week each year dedicated to these creatures to learn more about them and the world they live, in an area that is vastly undiscovered. There is enough evidence through fossils that can date the shark back four-hundred million years ago, which was a time before dinosaurs were roaming the Earth (“Shark Basics”).…
