A) Were the characteristics of all of the living specimens able to fit in the key, or were there some specimens that were difficult to place?…
The Sharks that I observed in the animal cam at the Blacktip reef exhibit at the National Aquarium in Baltimore is an ecosystem. I saw Blacktip Sharks, Clown Fish along with Manta Rays. They were many more organisms on the cam that I couldn't identify. This shows that there is a biological community. While on the cam I saw that the sharks even though they are predators never ate the smaller organisms it was as if they were protecting the smaller fish. This shows that there is interaction in the ecosystem. In the cam, there were reefs and underwater moss growing on the anemones. It had sunlight and water. This shows that they have a physical environment in the ecosystem because of the sunlight and water along with the reefs. The evidence shows…
I’m researching the Hammerhead shark it has many unique features . It has a oddly shaped head used for hunting . They live near the equator or in tropical waters . They are carnivores and eat about anything and their favorite food is the sting ray . The hammerhead shark is very unique .…
Since the 1970’s when the movie Jaws first showed up on big screens around the country, people have been afraid of beaches, in fear of shark attacks. Not only have they been apprehensive about swimming in the ocean, but some have such malicious feelings towards sharks (especially Atlantic White Sharks due to their role in the movie) that they have taken to hunting and killing this already dwindling species. (Earth Island Institute) It is no secret that pollution and overfishing, as well as numerous other factors have caused the biodiversity of marine life to drastically decrease. It is also known that the ocean ecosystem relies much on all members of the food chain- particularly top predators like sharks. Larger sharks,…
Most people are afraid of sharks and don’t want anything to do with them but there are people that actually know things about sharks and don’t fear them. Sharks much like people come in all different shapes and sizes and can and do live mainly everywhere. What people don’t know is that sharks are much like people they take care of their young by protecting them, feeding them, teaching them to hunt. They are thought of as cold-blooded killers but they aren’t they just do what they have to do to survive they hunt to eat they can’t go to a grocery store and buy food they have to hunt for it they will eat what they…
The shark’s identity has been destroyed by movies, documentaries and more. Movies such as Jaws, makes the public believe that the shark is highly dangerous and does not do anything…
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.…
In 1948 scientists presumed that the Lake Nicaragua shark, known at that time as Carcharhinus Nicaraguensis, was landlocked meaning it could not travel from the lake into marine environments, and that it was a separate species from C. Leucas (Thomas H. Lineaweaver, Richard H. Backus). It wasn’t until 1968 when scientists commenced studies on the sharks by catching them far into Lake Nicaragua as well as at the river’s mouth approximately 220 miles away. They made measurements, counted teeth, counted vertebrae and identified the sharks to be identical to C.…
Growing up, everyone wants to be in the pros, or an actor. No one wants to be around slimy and stinky fish until retirement age. But one person did. That person is Eugenie Clark. Eugenie did not call it quits at retirement age however. In fact, Eugenie would continue to dive and study sharks at the age of ninety-two (MOTE). In this paper, you will learn about Eugenie Clark’s life, her contributions to the scientific community, her educational background, the passion for which she did her job, scientists that worked with her to reach a common goal, awards that Eugenie has won, and the knowledge on sharks from before Eugenie’s time, during her time, and now sadly, after her time.…
When a group of people are different from us their way of living is wrong. That is what it seems to come down to when most conflicts in history are broken down. Men vs. women. Hippies vs. government officials. Blacks vs. whites. Jews vs., well, everyone.…
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”).…
1. In the story the truth about sharks the antagonists is Beth. She is a typical 17 year old girl that isn’t a morning person; however she seems welcoming and considerate. Hannah is a helping hand at the store Beth is shopping at; Beth takes time and talks with her, which ended up being beneficial to her in the end. Hanna is a flat character, although she is important to the story she isn’t described with a lot of detail. Madge P Groton is the security guard, she is the protagonist. From the introduction of Madge you could tell she was stern and not overly friendly. Another important character would be the officer that eventually listened to Beth’s story.…
As we see the droves of fisherman descending upon the docks to catch the most wanted shark, we meet Hooper from the Oceanographic Institute. He has come due to Chief Brody’s request to examine the first victim. During his examination of what is left of the first victim, Hooper says it is clearly a shark attack. Hooper and Chief Brody leave the examine area and see a group of fisherman on the dock with what they say is the…
Chondrichthyes were my motivation to get involved and stick with Marine Biology no matter the challenges. Growing up I found comfort in sharks. Due to media and lack of understanding sharks were viewed only as malevolent killing machines. I thought this false, constraining label was unjust and unwarranted. Just as sharks had a constraining label I was stereotyped to be at best average when it came to academics. I had a minor learning disability that made reading and writing a major obstacle. After a few years of before and after school programs, summer tutoring, and very little progress the expectation of every being a great student was thrown away. I was extremely dissatisfied with this lowering of standards and lack of faith. Shark Week and…
