Great White Sharks

Great White Sharks perhaps one of the most feared and misunderstood creatures on planet earth. Popular culture’s point of view of this wonderful and magnificent organism has been slightly skewed because of television and movies such as Jaws. Which depicts these great animals in a negative light typical of Hollywood. In a positive light this generated more interest among people to hopefully begin to understand this exceptional predator of the seas. Analyzing the fossil record of ancient sharks can be quite a bit difficult task since sharks are made of mostly cartilage which decomposes and leaves almost no trace. Paleontologists are left looking for fossilized teeth and jaw bones.

All sharks are extremely well suited for their aquatic environment. The Great White Shark physiology is far superior to that of any ocean hunter. Through evolution they possess six senses that enhance their ability to hunt; vision, hearing, smell, taste, touch, and electro-reception. These characteristics give a tremendous advantage to the Great White while looking for prey. They have supreme hearing with external ears located just above the eyes very difficult to see however the highly developed ear stones are able to sense the tiniest vibrations in their environment (http://ocean.si.edu/great-white-shark). One of the most interesting developments that Great White Sharks possess that humans would be extremely jealous of is the electro-reception. In the front of snout of Great Whites’ are pores filled with certain cells called the Ampullae of Lorenzini that can feel the power and direction of electrical currents (http://ocean.si.edu/great-white-shark). In these two examples of physiological traits the importance to Great Whites would logically make sense because of how sound travels in water versus air. When an organism is submerged underwater, vibrations would…...

Great White Fire

...chain-link fence, kept reporters far from what remained of the building itself. During the first daylight hours, news helicopters flew overhead, disrupting the tarps erected by firefighters to shield the dismal recovery effort from nosy eyes. That vantage point was lost after one Helo got too close to the site and it blew open body bags containing victims’ remains. Immediately, the FAA declared the site a “no-fly” zone. Video of the fire from ignition to tragic human crush, had already been broadcast throughout the United States and abroad, because a news cameraman happened to be shooting inside the club a documentary in the wake of another tragic club just days prior. The world had saw the horrible images: an ’80s heavy-metal band, Great White, sets off pyrotechnics, igniting foam insulation on the club’s walls; concertgoers’ festive mood changes in 90 seconds to puzzlement, then concern, then horror as flames race up the stage walls and over the crowd, raining burning plastic on their heads; a deadly trap forms at the main exit. 4) Response- The immediate actions to save lives, protect property, and meet basic human needs. From the time of ignition to the point where the facility was well involved in flames less than 6 minutes passed. The initial 911 calls for assistance were received from cellular phones at the scene. The police officer stationed at the club on a paid detail notified his dispatcher of the fire as well. The West Warwick Fire Department, upon......

...Endangered Sharks Rapidly declining shark populations has already been noticed and will continue to decline unless further steps are taken to ensure their protection as endangered species. 50 out of 307 shark species, listed by the International Union for Conservation of Nature (IUCN), are either vulnerable, endangered or critically endangered. However, of those 50, only three, the White, Whale, and Basking sharks are protected internationally under CITES. CITES is the Convention on International Trade in Endangered Species. Sharks as a whole, represent the highest percentage of threatened marine species listed on the IUCN Red List of threatened species. Some well-known species that are endangered are Hammerheads, Tiger Sharks, Whale Sharks, Great White Sharks, Shortfin Mako Shark, and many tropical reef sharks. The decrease of shark populations has already had devastating effects on local coastal communities. Two of the world’s largest fish are on the endangered list. The Whale Shark is listed as vulnerable for extinction. They migrate seasonally and are targeted by commercial fisheries. Whale sharks feed on krill and plankton so they do not harm humans, the most harm one could face would be to get struck by its massive caudal, tail, fin. Whale Sharks are beneficial to many tropical reef areas. In addition, the Basking Shark is also listed as vulnerable. These are the second largest living fish left. They are found in all the worlds’ temperate oceans and are a...

...Bloodthirsty, ruthless, killer: shark. For years people have feared and slaughtered sharks because of the bad rap they have received from Hollywood, but these beliefs are not justified. Sharks are not vicious and are actually quite gentle. Of the more than 388 species of sharks only two (the Great White and the Tiger) have been known to attack man and then only because of mistaken identity. Wetsuits and surfboards used by surfers are mistaken by sharks as the thick, rubbery, skin of seals, which are their main diet. Once the shark bites the surfer, it almost immediately lets go because it does not taste like its favorite meal. Not all big sharks have huge jaws full of teeth, as many people believe. Whale sharks, the largest fish in the world, are the most affable creatures you will encounter in our world's oceans. These sharks (that can weigh over three thousand pounds and grow up to five stories in length) have no teeth at all. Instead they have a mouth full of baleen that they use to filter plankton and tiny fish out the hundreds of gallons of sea water that passes through their monstrous mouths at one time. These peaceful giants have been known to let divers ride on their backs and don't show any aggression when approached. People should treat sharks with respect, as they should all earth's creatures. The only way for future generations to learn to appreciate these magnificent creatures (instead of fear them) is through education. This can be accomplished through...

Basking Sharks

...Basking Shark In the midst of all the masters of the sea, comes an enormous atrocious sea creature. It is known for being the second largest species of sharks in the world and also a fascinating monstrosity. Cetorhinus Maximus, also known as Basking sharks are fierce yet bizarre lethargic sharks. They are known for their gigantic mouths and unique appearance, which sets them apart, and additionally are quite impressive. According to “The Shark side of Life” it states that, “These sharks can grow to lengths of over 35 feet (10 meters), thus making them the second largest fish in the ocean ("The Shark side of the World ").” Due to their colossal appearance, this particular shark has few enemies. Basking sharks are very independent and known to depart from their mothers once born. They are ovoviviparous which is a form of reproduction where the eggs are internally fertilized as well as hatched within the female bearer which she gives birthed to fully young sharks. In addition to their eccentric process of reproduction, Basking sharks are oophagous, which means that the mother produces infertile eggs to nurture the fertile eggs, as a source of food. According to Sharks Trust, it states “Gestation periods of 1–3.5 years have been proposed though this figure has recently been revised to around 14 months. Estimates of the size at birth range from 1–1.7m, making Basking Shark pups larger at birth than the majority of other sharks are when fully grown ("Shark Trust ").” This......

...Running head: Sharks Sharks T Tolerico Marine Biology Doctor Cameron Guenther Sharks What do you think of when you hear the word “Shark”? Do you think of the lion of the ocean or perhaps God’s perfect predator/scavenger? Perhaps you think of the movie “JAWS”? Most people will think of the movie “JAWS” and think killer, attacker, and predator. However, are sharks really preying on humans? I view sharks as God’s perfect predator and scavenger. Sharks, like lions, weed out the sick and slow fish to keep the population strong. They also scavenge on the bottom of the ocean any carcasses that settle there. The attacks on humans are more likely the shark “tasting” to see if the movement is a fish. When the shark realizes that the human is not its prey, they move away. Sharks can be found all over the world’s seas, from the equator to polar regions. We are currently aware of about 480 species and there are still species to discover. Some species, known as benthic, dwell mainly on the ocean floor. An example of a benthic is the nurse shark or ray shark. They scour the ocean floor for food. Other species are known as pelagic, meaning they spend much of their time navigating the open seas. Most of the species that we are familiar with are pelagic. Some species even inhabit rivers and lakes. The Bull shark can migrate into rivers and lakes. One important feature of sharks is that they are made up of cartilage not bone. There has been research done on shark......

...Shark Killing and the Ecosystem Introduction Sharks are fascinating creatures that come in all sizes and live in water all over the world. Arguably, these creatures play a very imperative responsibility in the ocean that a fish cannot. Apparently, sharks are the top food providers in the ocean almost in every part of the world. In this case, they assist in keeping the inhabitants of other fish species healthy and in suitable proportion for their ecosystem. However, shark population faces the threat of extinction in almost all parts of the world due to overfishing. Fishers us a technique called Bycatch, a process in which marine mammals or species of fish are unintentionally, caught while fishing for a specific target. Irrespective of the initiatives and laws put in place for overfishing, fishers have continued to hunt sharks for the fin soup, which is in high demand than their meat. On the other hand shark cartilage and shark liver oil are sold as cures for the hosts of aliments. Due to this disparity between meat and fins, it has led to a horrific practice of shark fining. As a result, there is need to create awareness on the importance of sharks in all parts of the world in order to save ocean ecosystem from extinction. Catching Techniques Many fishing techniques and gear are no selective and result in catching and discarding millions of marine life that is not always the target species. Most of the fishing methods like the long line typically are used to catch tuna.......

...Sharks One of the most feared predators of the ocean are the sharks, with more than 465 known species of sharks living in our ocean today. They are very popular animals with movies such as Jaws and Deep Blue Sea, these animals are also dedicated a whole week on animal planet they are often categorized as monstrous savages who just attack any and everything. In fact that isn’t a true reputation of them. These animals are survivors and have been around for a long time. These fascinating creatures have caught the eye and imagination of so many people as well as me. There are many things I want to cover over today just to give a better understanding and idea of sharks. Sharks are very smart creatures so its no surprise to learn they have plenty of ways in effective forms of communication. Eventhough sharks are generally loners, so they aren’t in groups. This makes it harder for scientist to observe how they actually communicate with each other than with other animals that live in the water. They have an amazing sense of hearing which is believed most likely to be how they communicate majority of the time. They can hear sounds at very low frequencies so a great part of it won’t even be picked up during the test observations. Sharks also use their hearing to allow them to pick up vibrations and electrical currents from other sharks in the water with them. Most of the communication among sharks involves aggression. They will fight each other not for territory but for food. For...

Shark Fin Soup

...Katharine Jenkins-Moore Stephanie High Eng 111 24th of November, 2013 Saving the Great White Shark Great White sharks are being killed to the point of extinction. Overfishing, finning, and the fear of humanity are going to be the death of these majestic creatures if we do not do something about it soon. Great White sharks have been called “the barometer of our oceans”. If they are no longer around, our whole ecosystem will go into a terrible tail-spin that we will be helpless to stop. Solutions to these issues can be found by making some big changes, but mostly a lot of people making small ones. Great White sharks are in danger, and if little things are changed in people’s daily lives, we may be able to reverse, or at least halt, the threat. One major problem Great White sharks face is finning. Finning is defined as the catching of a shark, pulling it aboard a boat, cutting off all of the shark’s fins, then throwing it back into the ocean to either be eaten alive or drown. Author Rebecca Tatum states in her academic journal “The Ecology and Controversy of Shark-Fin Soup” that “Shark-finning is increasingly illegal on a global basis; since 2004, at least sixty nations have banned the practice” (Tatum 6). Many specials have been aired (on Animal Planet) about the shark fin trade. One could see fins drying on rooftops for miles. Tatum also states “The extraordinary value of the fins, up to $2,000 per pound, incentivizes this wasteful practice” (Tatum 2). The price paid...

...Are sharks perfectly adapted predators? This essay will discuss how sharks are thought to be one of the most perfectly adapted predators in the ocean food chain due to their physiology and interactions with their environment. However we must not disregard the fact that there are many species of sharks which may possess different features meaning that only certain species may be considered ‘perfectly adapted’. It is thought that sharks have been around for around 400 million years, in which they quickly evolved to the environment they live in. The sharks we see today are believed to be the result of evolution that took place 100 million years ago, making them largely unchanged over this time period. The most recently evolved sharks are the sphyrnids (hammerhead sharks) and the carcharhinids (requiem sharks). Although the reason behind why these sharks have survived could be due to early adaptation to their ecological role, we must consider those species of sharks that are now extinct and understand why certain species adapted quicker than others. Sharks main defining feature is their cartilaginous skeleton, placing them in the class Chondrichthyes, which is thought to make up only 1% of living fishes. By having cartilage as opposed to a bony skeleton they are lighter and more flexible in the water, as well as the cartilage strengthening the body frame of the shark. This class of fish are commonly known for their paired fins, paired nostrils and jaws and can then be......

...in so many shapes and kinds as the shark. The earliest evidences of sharks are isolated spines, teeth and scales that appeared about 430 million years ago in the Silurian Period, known as the "Age of Fishes". Sharks have a sleek, streamlined design which helps them swim without using up a lot of energy.They certainly need to conserve their energy because they never really sleep and most of them never stop swimming. Some sharks are fierce predators, and would be happy to eat you if they encountered you. Almost any shark six feet or longer is a potential danger, but three species have been identified repeatedly in attacks: the Great White Shark, the Tiger Shark and the Bull Shark . All three live world wide, reach large sizes and eat large prey such as marine mammals or sea turtles. But most sharks never grow longer than five feet and never even see anyone with legs and arms anyway. People kill thousands more sharks every year than sharks kill people. Sharks take about as long to mature as we do. Some of them become adults in their teens. A mother shark carries her babies inside her body while they develop, sometimes for more than a year. Even so, some sharks are born inside an egg which they have to crack open. They spend early portions of their lives in nursery grounds. Some of the advantages sharks have over people is that they keep growing new teeth, they don't have breakable bones, and they are not prone to get cancer. Sometimes sharks are referred to as swimming......
