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
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
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
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
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
mind when you think of sharks? Sharks make people think of death and fear. As you will be able to see after i discuss types of sharks, their habitat,the food they eat, and their intelligence. They don't seem as bad as you think so. First sharks live a habitat under the water in the sea. Sharks live in many different oceans. They live in the the pacific ocean, Atlantic, Indian,and the Arctic. Mostly all sharks live in salty water, but some sharks live in the river. Sharks live in coral reefs under
Sharks now are a lot more dominant than they were before, seeing something put up a fight with a great white is very rare. Most sharks are carnivores and do not seem to have very much competition for food because of their size and ability to hunt. Not all sharks now are at the top of the food chain but for the most part there are not many other creatures that will put up a good fight with a shark. Just like an creature on earth as time goes on something’s are no longer needed and eventually with
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 asked
Sharks Sharks are one of the most feared carnivores in the sea. There are 365 species of of sharks in the sea as we know today. All sharks are carnivores. Most of them eat live fish, including other sharks. A shark's most common natural enemy is an another shark. Most sharks eat their prey whole, or they tear off large chunks of the bodies. Some sharks crush their prey. Others take out small pieces off flesh from large fish. Sharks also feed on dead or dying animals. Sharks have the reputation
knows the shark gets it in the end. What they do not know is that too many sharks have gotten it; and that has caused a rapid decline in the shark population over the past thirty years. Since the 1970's, sharks of the Atlantic and Gulf of Mexico shores have declined eighty-five percent. Sharks are vital animal to our world's ecosystem, and if the decline is not controlled; we could be facing devastating problems in years to come. Information has been obtained from two books: The Shark Almanac
Sharks are one of the most endangered species in Australia, and it’s our responsibility to help protect these sharks from being over-fished. Many fishing markets fish sharks but deteriorate physical features that help with distinguishing sharks and is very difficult to differentiate between them, since they are produced the same way- as fish and chips. In this experiment DNA samples have been taken from sharks from the NSW Shark Meshing Program. The DNA was extracted and amplified for the production
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
explanation on how one of nature’s apex predators, the shark, and how the way sharks hunt and track down their prey. The hunting process for sharks will be explained in sequencing order starting from how sharks sense their prey, to how the way sharks stalk their prey, and what happens when sharks capture their prey. Also a brief explanation will be discussed about how two peculiar species of sharks, Hammer head sharks and Long nose saw sharks, about their body shape, their diet plan, and how the way
Shark finning is something that should be illegal because shark are animals that should not be hurt for no reason. Because sharks are living creatures that under no circumstance should suffer. Shark finning is the process in which you cut off a shark fin in order to sell for a very large profit to make shark fin soup, this wasteful and often cruel practice contradicts all principles of sustainable shark. Shark finning is something cruel and violent, it affects the population of sharks. It’s something
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 fin soup is a popular dish in the Chinese culture and it is mainly served in special events, it consists of a shark fin and chicken. It is mainly consumed by a wealthy minority. Although many people in the chinese culture seem to enjoy this popular delicacy, the shark population is declining, through the process of shark finning. Shark finning begins with the removal of the shark’s fins, once all of the fins are cut out, anything remaining left from the shark is thrown back into the ocean
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
Sydney Swiatkowski Lamar Hill English III Honors 21 May 2014 It is no secret that sharks have a bad reputation for being blood-thirsty man-killers. Sharks are known as the “killers of the sea.” Every year, on average, 10 people are killed by sharks; however, every second 3 sharks are slaughtered by humans. So who is the real “killer of the sea?” Sharks are victims to a cruel and inhumane practice known as finning. Finning is a practice that is more practiced in the pacific today but used to be practiced
