Hammerhead Sharks Marine Science/ Per. 1 Sharks are one of the most feared sea animals. They live in oceans across the world but are most common in tropical waters. There are over three hundred fifty species of sharks. They can be broadly categorized into the following four groups: Squalomorphii, Squatinomorphii, Batoidea, and Galeomorphii. The shark family Sphyrnidae that includes the Hammerheads are part of the Galeomorphic classification. They are probably the most easily recognizable of all
develop more successfully in the environment they inhabit. One such case of this successful development is the great hammerhead shark. The great hammerhead shark, also known as Sphyrna mokarran, is a pelagic shark and is found world wide in tropical warm water regions. Great hammerheads are the largest species of hammerhead shark. The great hammerhead can be distinguished from other hammerheads by the shape of its “hammer” (called the “cephalofoil”), which is wide an almost straight front margin, and by
You are smelling the salty water around you and you suddenly feel something pass your leg.It`s a bull shark waiting to devour you.These species and the hammerhead are the two species of shark that you would not want to be noticed by.Both species are extremely dangerous and deadly.Bull and hammerhead sharks have many similarities and differences.The differences between these two species concerning apperance,diet,size and other important factors of the species` lives are important to know in case of
In The Cask of Amontillado, Poe describes the picture on the crest as a golden foot crushing a serpent, which has its fangs imbedded in the heel of the foot. Poe also mentions the motto “Nemo me impune lacessit (no one provokes me with impunity)” told by Montresor to Fortunato, which signifies the analysis of this profound picture on the crest. According to the plot of the story, the foot represents not only Montresor but also his status-consciousness and cruelty towards Fortunato. As image of the
Ribbon There once was a ribbon. Her name was Ribbon, as plain as the decorative object that she was. Ribbon was very vain and liked to get up every morning from her place in the sewing basket full of odds and ends. Every morning, she would look into the small pink hand mirror that would be lying beside her in the sewing basket. She would see the cutest, most beautiful face in the whole world every morning and was delighted. Then Ribbon would reluctantly stop admiring herself and would begin to
Ribozymes are catalytic molecules that cleave the ribonucleic acid (RNA) at specific sequences (Gesteland et al. 2006). RNA is the nucleic acid that is made in the process of transcription; when the deoxyribonucleic acid (DNA) anneals, it transcribes itself into a linear stranded molecule called RNA. In order for RNA to synthesise proteins, it requires catalytic enzymes to perform certain chemical reactions. In the past, it was thought that all chemical reactions are catalysed by protein enzymes;
Shark nets have been implemented in locations across the world in response to shark sightings and attacks. Nets are submerged beneath the surface of the water, roughly 200 metres from the shoreline. The meshing is designed to be large to capture sharks, leaving them to struggle before eventually drowning under the weight of their own body. The meshing allows small fish to pass through, however captures larger fish and marine species. Shark nets provide no discrimination between common, vulnerable
Shark finning should not be allowed since poachers are throwing away shark carcases back into the ocean wasting away the majority of meat and only keeping the fins making the shark population decline rapidly, it is also inhumane to kill any animal in such a manner, and the loss of sharks are destroying ecosystem. I completely disagree with the waste of sharks and the idea of killing mass populations of sharks for just fins, the results are more severe than one would think since other populations
Sharks have several ways to dispatch their prey with surprise attacks, agility, and camouflaged sneak attacks. The shark’s dentition also tells the story of their diet as well as their method of attack. The Great White Shark, (Carcharodon carcharias), is the largest extant predatory shark on Earth and has large serrated teeth that tear through the flesh of its prey. Their teeth are 2.5-3 inches in height and have prominent serrations which allow them to tear large chunks out of prey including
Most people just know of a few sharks like the great white or the tiger shark or the hammerhead, but there are many more. There are more than 400 different kinds of sharks. There are some that are smaller than a ruler. One of the smallest sharks known is the Pygmy ribbon tail cat shark. The biggest ones are around seven inches long! These
wide world of sports ranges from the predictable to the obscure. You can play korfball with the people of the Netherlands, go to the extreme ironing world championship near Munich, Germany, or play underwater hockey or rugby with the New Jersey Hammerheads, or any of the other seven teams in the United States. No matter how strange these sports sound or seem, people play them. Korfball is a co-ed sport similar to basketball, except it is typically played on a large, grassy field. The game is fairly
Arctic. Mostly all sharks live in salty water, but some sharks live in the river. Sharks live in coral reefs under the water, but a lot of the time they are swimming around hunting for prey. Next there are over 400 different species of sharks. Hammerhead sharks are the most recognizable fish in the sea. They also have eyes
Sharks are widely viewed as frightening, vicious predators that feast without hesitation on all fish in the ocean and occasionally even an unlucky human. When humans picture sharks, they see giant monsters that terrorize the ocean and its inhabitants. In reality, it's the other way around. An estimated 100 million sharks are killed by humans every year through illegal fishing, environmental issues, and shark finning. Sharks, however, average only 19 attacks on humans in the U.S. per year and only
Hundreds of people, who get in the ocean every year, are almost none that encounter sharks. Even if you're lucky enough to see a shark big enough to bite you, you're much likely to die from a heart attack than getting bit by one. Shark attacks are mistakes and the idea of a shark off every beach waiting for people to come in the water is completely untrue. I will inform you on the background knowledge of sharks and the reasons why humans should not be afraid only aware. Most people think that

If you have nothing better to do can actually hear this bird call on the site: “Yellow hammerhead nest, Emberza (New Zealand Birds).” “Beethoven was present at the creation. The grafting of “fate knocking at
The Great Barrier Reef What is the Great Barrier Reef? The Great Barrier Reef is a huge, colourful and bright coral reef, situated off the coast of Queensland in the Coral Sea. It is so big that it is the only living thing that can be seen from Space! It consists of over 2,900 individual reefs and 900 islands that stretch over 348,700 km². It is in a wet, tropical climate with reasonably warm Winters and a high humidity in the Summer. Water temperatures span from 14 degrees Celsius in the Winter
The Wizard of Oz is a fiction story written by L. Frank Baum. The story has two main settings. The first setting is, Dorothy’s home, the Kansas prairies. The prairies are described as dry and gray. The second setting is the land of Oz. Oz is opposed from Kansas, it is colorful, bright, and full of joy. The Wizard of Oz has a grate theme or message behind the story. The message is that we all have good qualities in us, but it is up to us to use them. The story starts off when a cyclone that hits the
shock and amazement they feel after coming upon a shark in the open ocean. On one hand, Dickey begins by labeling a hammerhead as “unstirrable” (1), giving readers an opportunity to visualize the shark as an immense being with a very noticeable, presence that cannot be ignored. He continues to carefully illustrate the shark’s movement, describing how the “dreaming” (1) “hammerhead goes by the boat, passing [him] slowly
INTRODUCTION Although sharks belong to the class Chondrichtyes, there are many different types. Sharks arose about 350 million years ago and have remained virtually unchanged for the past 70 million years and still comprise a dominant group. It is thought that sharks almost certainly evolved from placoderms, a group of primitive jawed fishes. It took a long series of successful and unsuccessful mutations with fin, jaw positions etc to give us all the different designs of sharks around today. When
Sharks have lived on Earth for more than 400 million years. There are between 450 and 500 known species of sharks. Sharks are one of the most important species that wander the Earth. They are in charge of keeping the marine ecosystem healthy. Being one of the biggest predators in the sea, sharks have an essential role keeping the food chain organized; making sure species below them don’t exceed in number, or the opposite. By removing the weak and sick of a species, sharks make sure diseases don’t
