Lars Gustafson 11/4/15 GEOG 304 Research Paper: Shark Finning With an alarming one in four shark species endangered across the globe, we have come to a breaking point where our oceans ecosystems could suffer permanent damage if the practice of shark finning in the oceans off of Eastern Asia continues as shark population’s plummet. According to www.stopsharkfinning.net, tens of millions of sharks are killed every single year just for the fins that are the main ingredient in shark fin soup. Shark fins are harvested to feed the growing demand for shark fin soup that is an Asian delicacy food. When the sharks are finned they are usually thrown back into the water and left to drown slowly. Sharks rely on their fins to swim and allow water to
Whale Sharks the largest fish in the world and are found throughout the warmer areas of the oceans. Whale sharks can reach to 18 – 40 feet long and weighing from 12 - 20.6 tons (Bradford A. 2016). As filter feeders, whale sharks eat mostly plankton and other small organism such as zooplankton, copepods, shrimp, phytoplankton, mollusks, and sardines. Whale sharks capture their food by swimming towards it with their mouth open which can get up to 4.9 feet wide and engulfing their prey that enters their mouth (Rafferty J.
Since the display of captive whales has begun, one hundred and fifty-four people have either been injured or killed by a whale attack (Jacobs). For instance, Dawn Brancheau was killed by the tix ton bull orca whale, Tilikum (”Should Orcas Be Kept in Captivity?”). Tilikum was separated from his mother when he was two years old and had been moved from park to park his entire life. The separation issues from losing his mother and never having a true home had an immense physiological effect on Tilikum that caused him to lash out and kill one of the most experienced trainers at Sea World. Another instance of a deadly killer whale attack happened in Spain.
All is quiet in the beautiful ocean then you hear a scream then you look out into the ocean and the only thing you could see was a shark tail. Older Than Dinosaurs? Sharks have lived on the earth longer than you think for example, over three hundred years ago sharks roamed in waters, that is one hundred million years before dinosaurs roamed the earth! Some of the sharks that roamed long ago don’t roam today, on the other hand a handful of the sharks that lived then still live today. Who knows there may be more sharks in the deep of the ocean that we don’t know exist, most of the ocean has not been searched.
In 2004 in Indonesia a 9.0 earthquake hit and created a tsunami that killed about 250,00 people and the author Richard Lewis recreaded the story in the killing sea because he is interested in the mysterious ocean. First on page 48 the narrator said “for as far as Ruslan could see, meulaboh had become a lake, clogged with floating debris”. this is true because meulaboh was one of the first places that the tsunami hit so all the ocean water was there and went through many cities and destroyed pretty much everything there.throughout the book Ruslan finds dead bodies and so did many of the rebels, it said that on page 49 the narrator said”across the way, ruslan can see dozens of bodies crumpled on second floor stairs of the shopping mall.” because of the tsunami, about 250,000 people had died so there would be many dead bodies everywhere and inside of every building, but especially in the shopping mall because people like to go to the mall so there would be a lot of people there. Then on page 18 the narrator said”from up top came peter exited cry.”hey, the reefs are drying up! there 's fish flopping fish around!”” in meulaboh,before the tsunami hit the reef dried up and groups of people were just standing there looking at the reef and there actually was fish flopping around, but then the tsunami hit and killed all of the tourists that were just standing there.richard Lewis accurately represented the tragedy of the tsunami in Indonesia and added a few characters that made
There have been multiple incidents at SeaWorld when killer whales have attacked people. The most popular killer whale attack is the death of Dawn Brancheau by Tilikum, the largest male orca captive at SeaWorld Orlando. This was just one out of three deaths that Tilikum was involved in. He also played a part in the deaths of trainer, Keltie Lee Byrne, and park visitor Daniel Dukes. An autopsy completed by Dr. Joshua Stephany, a medical examiner, determined the injuries Brancheau had sustained after Tilikum had pulled her into the pool.
Imagine, a 22.5 feet long killer whale that weighs 12,000 pounds, slammed and dragged a person in the water who only weighed 125 pounds. The image is gruesome but that’s what happened to SeaWorld trainer Dawn Brancheau. A respected 40 year old who fought hard to stay alive against the largest orca in captivity. Accordingly to witnesses Tili (short for Tilikium), the Orca went wild during the Dine with Shamu Show, then attacked and killed Dawn. The event shocked everyone because Orcas are usually very friendly but Dawn Brancheau was the third victim of Tilikium.
The Jersey Shore shark attacks of 1916 were a series of shark attacks along the coast of New Jersey, in the United States, between July 1 and July 12, 1916, in which four people were killed and one injured. Since 1916, scholars have debated which shark species was responsible and the number of animals involved, with the great white shark and the bull shark most frequently cited. The incidents occurred during a deadly summer heat wave and polio epidemic in the Northeastern United States that drove thousands of people to the seaside resorts of the Jersey Shore. Shark bites on the Atlantic Coast of the United States outside the semitropical states of Florida, Georgia, and the Carolinas were rare, but scholars believe that the increased presence
The Permian-Triassic extinction The largest of the Big Five was the end-Permian or Permian-Triassic extinction event roughly 250 million years ago, which eliminated as much as 95 percent of the planet 's species. Before this extinction, marine animals were mostly filter feeders stuck in place on the seafloor, such as crinoids or "sea lilies." Afterward, the seas became far more complex with mobile creatures such as snails, urchins and crabs. The most likely final trigger for the end-Permian was again massive volcanism, this time at the Siberian Traps, which spewed as much as 2.7 million square miles (7 million square kilometres) of lava out, an area nearly as large as Australia. Recent evidence suggests, however, that the end-Permian may have
Human beings can be attacked by sharks. Most shark attacks are caused by particular shark species. They include Carcharodon carcharias, Galeocerdo cuvier, and the Carcharhinus leucas. Historically, shark attacks are on the decline following increased global awareness on the menace. Shark attacks are most common in the United States waters than the rest of the world because of difference in climatic
Kissimmee River, is one of the most beautiful rivers in the world. The Kissimmee River is often compared to the Nile and the Amazon River. Surrounded with wetlands, marshes, plant vegetation, bald eagles, deer, alligators, fish, and birds. Florida was struck with hurricanes in 1926 and 1928 disturbing Florida 's ecosystem. The Hurricane in 1928 was the second deadliest hurricane in US history, causing massive flooding from the storm surge of Lake Okeechobee with over 2,400 deaths.
Mako sharks are currently listed as Vulnerable species(Beardsley, 2015). A vulnerable species means if their their birth and deaths rates decrease, they will become endangered. Humans hunt Makos for sports and food(Gray, 2014). For example, they make shark fin soup with Mako sharks. To protect the Mako Shark species, they are protected by U.S. waters(Beardsley, 2015).
Baitfish, Menhaden (Brevoortia sp. ), containing high concentrations of breve toxins were the most common prey identifiable in dolphin stomach contents, revealing the source of the breve toxins” (Effects of Florida’s). The same thing happened in 2002 where thirty four endangered manatees died in Florida and again in 2004 when 107 bottlenose dolphins died off the Florida panhandle. “In the spring of 2002, 34 endangered Florida manatees (Trichechus manatus latirostris) died in southwest Florida, and 107 bottlenose dolphins (Tursiops truncatus) died in waters off the Florida panhandle in the spring of 2004. In both of these unusual mortality events, extensive water surveys revealed that only low concentrations of K. Brevis were present” (Flewelling, L. J., et al 755).
Usually killer whales prey on about 30 species of fish. On average, a killer whale eats 227 kilograms (500 lb) each day as it needs lots of food to sustain itself. Killer whales hunt in a very strange way called carousel feeding. They force fish into a tight ball by releasing bursts of bubbles .They then slap the ball with their tail flukes, either stunning or killing up to 15 fish at a time. The fish are then eaten very slowly, usually one at time.
