Scientist are trying to find a way to keep the petrifying creators called sharks from harming their self’s and people. For instance, researcher found out magnets and electricity mess with these overgrown fish’s Ampullae of Lorenzini, which are special sense organs that assist with them finding their pray. Sharks are causing problems for humans and two ways to effectively solve this problem is with magnets and electricity.
While, these horrific fish are bloodcurdling there is ways to keep them away, such as a magnet. “Magnets made from iron, boron, and neodymium is a promising repellent being developed by SharkDefence” stated in Stopping Sharks by Blasting Their Senses. Magnets effect the shark’s Ampullae of Lorenzini. Another way, is specified
in Stopping Sharks by Blasting Their Senses is “rotten shark keeps live ones away…it’s like they were punched in the nose”. Instead of killing the sharks why not just repel them. There are a million different ways to repel sharks rather than killing them. Furthermore, image if you were shredding the nar then a colossal man eating beast jumps out of the water and eats you. For instance, surfers take up about 50% of all attacks. The surfers are invading the shark’s habitat. To add to the list, “the Shark PODs can mount to a surfboard or a diver’s ankle that uses a pair of electrodes to emit a three-dimensional field around the user” defined in An Electric Fence Ward Off Sharks. The electricity messes with the shark’s special scene. For example, “research conducted by the University of Pretoria in South Africa also found that the device reduced the probability of an attack from 0.70 percent to 0.08 percent” explained in the article An Electric Fence Wards Off Sharks. While, the device reduces attacks, an attack may still happen. These blood thirsty fish may attack the Shark POD will reduce the chances of one. To conclude, there are many ways sharks causes problems with humans, but there are some solutions. Magnets, electricity, and Shark PODs all reduce shark attacks. The best way to reduce a shark attack is magnets.
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 and endangered species, resulting in a high mortality rate for a variety of marine wildlife.
...s. According to studies and statistics done, you are more likely to be struck by lightning than killed by a shark. They are often misinterpreted as scary and violent creatures, however this is merely due to media. Shark based films such as Jaw show that these sharks are harmful when they really aren't. Tapes/recordings of sharks slaughtering humans are published so often because of its actual unusualness.
the drum- lines program with hooks like needles is working even though sometimes it’s a false call but it is keeping every one safe so far. In my opinion, I think that the main reason there is shark attacks because of crowded beaches. I think that because there is so many people in the water that you can’t sea your surroundings.
Sharks have also been subjected to medical research, games and competitions, jewellery, souvenirs and cosmetics. We need to take into consideration that sharks play a vital role in the natural world that we live in. it is imperative that we look after these majestic creatures and ensure they remain protected. We need to be aware of the dangers of sharks, swim in protected areas where there are shark nets, and do not swim after dark in the sea (especially not alone) as the sea is the sharks home. Humans should also be wearing wet suits as protection in the ocean. The sea is where they live, they swim freely and they eat – they do not particularly target humans but rather prey on food that is available to them in their habitat.
Australian beaches are some of the best in the world and WA beaches are some of the best in Australia. But this may soon no longer be a view held by everyone if the WA government continues to support and allow the shark culling off Perth's major beaches. Hi I'm Maya Koentgen, a marine biologist, ecologist and fellow beach user, and I'm here to tell you why shark culling needs to stop. At the moment hundreds of innocent sharks are being caught and killed and why? Because they are simply swimming in their own homes that us humans have invaded.
...te shark slaughter all around the globe. The easiest way to help stop this is to go to one of the many websites developed for this very reason, and support them. Sharks cannot speak for themselves, so we must speak for them and stop shark slaughter!
In 2015 only 59 shark attacks have occurred around the world compared to the millions of sharks killed by humans every year. Due to these accidental shark attacks people tend to think that sharks, especially Great Whites are evil creatures with malice intentions when attacks do occur; but, on the contrary that is wrong. Sharks are not the only beautiful and unique creatures in the ocean, they also play a vital role in our ecosystem; however, due to human interference they might not be around much longer, through awareness sharks can be protected from endangerment.
Attention Gainer: For the attention gainer, I plan on showing the audience a two minute and thirty second video in order to display the tragic events that are happening around the world regarding shark killings. My attention gainer will enable the audience to become aware of the situation as well as invoke a serious and potentially sad mood in the classrooms, before I begin to touch on the terrible situation we have
Thesis: Sharks should be conserved because they are an important part of the ocean, attacks are often incidental, and human behavior influences the behavior of sharks.
In Chinese tradition, Shark fin soup is called as “a celebration soup”, which people eat it to celebrate in various occasions. Moreover, people also believed that shark fin consisted of diverse nutrition values which provide them virility, wealth, and power(Wolchover, 2011). These beliefs lead to the beginning of poaching for sharks, the top of food chain in the sea world. Surprisingly, although people are aware of the decreasing number of sharks since the old days, around hundred million of sharks are still hunted each year(Heltus, 2013), to be served on luxury tables surrounded by those believers in things that they do not even prove whether the belief is reliable. Therefore, in the generation that people are mostly educated, sharks should no longer have to be continuously killed for their fins.
Sharon Guynup says, "Most sharks are harmless,” (“What Do You Know About Sharks?” 872). Over 300 species of sharks are harmless to humans, and the ones that are harmful do not attack often. Peter Benchley states, "Only four [sharks] attack human beings with any frequency," (“Great White Sharks” 890). When people swim, they should not be afraid of being attacked by a shark, especially if the area is not known for shark attacks.
Shark nets, shark spotting, apps, traditional and smart drum-lines, sonar technology, tagging, shark barriers, personal repellents, coloured surfboards, shark deterring wetsuits etc. The government has tried many systems to prevent shark attacks rather than shark culling but none of them have worked. I could one by one talk about why each of these methods have not worked but let's just stick to one. Shark nets. You may be asking yourself, what are shark nets or what do they do? Well, they capture sharks that come too close to shore grounds, then the nets release them back away from the shore. Smart idea right? No. It's time we acknowledge that shark nets don't work and instead do harm to other harmless marine species. The latest report on the NSW Shark Netting Program revealed 133 targeted sharks were caught with the nets along with 615 non-targeted marine animals. Almost half of the non-targeted marine animals were found perished. We need to come to the realisation that shark culling is the most effective
They are creatures that have no clue what we are and are afraid of us. Every year, thousands of more people are killed by other people than by sharks; thousand more people are killed in car accidents than by sharks, and more people are killed by lightning strikes than by sharks. Each year humans kill tens of thousands of sharks, yet, there are fewer than 100 shark attacks upon humans. For example, The Great White shark also known as the man-eater, has the greatest reputation for attacking humans. Recent studies of Great Whites show that they mainly feed on sea-mammals. Seen from below the surface a person swimming with a shark looks much like a seal, with arms and legs sticking out. The shark usually surprises its victim, being a person or seal, by one massive bite, and then retreats in order to allow the victim to die before digesting the food. For this reason, many humans survived the attack of a Great White shark if they are saved before being eaten. Not only getting out of the water and be safe, but the result of loss, blood or
My Freshman year of college, I remember there being this night called “Shark-Night”. It’s the first night that sorority women are allowed to talk to men and drink. This night usually happened on a Friday, where all of the freshman women would take to fraternity houses. It was said by many of my friends that this was the night that the freshmen men would “prey” on freshmen women. It’s a tradition that my Greek system is trying to get out of, but it’s still there.
The lorenzini is a pit-like organ located on the head of the whale shark that senses weak electrical and magnetic fields. This is an area that is currently being researched extensively and is largely unknown. It is speculated that this organ is used by the whale shark as a navigational aid through using the earth’s magnetic force (Rowat 2012).
