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 sharks are large, fast-swimmers, and savage predators. This is true of some species and groups should be interested of the appealing aspects of biology found within it: all sharks have an excellent sense of smell; some can detect electrical discharges; some sharks give birth to one of the …show more content…
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
You are a 200-year-old endangered Hawksbill Sea Turtle twisting yourself into a foreign knot. Thrashing for freedom, panic sets in as your realise you are helpless in your bending cage. The ocean turns from turquoise green to Prussian blue as the sun slowly pierces the shadows of your watery grave. Bubbles rush from your mouth like stolen phantoms as you begin to contemplate your own mortality. Slowly suffocating, hope begins to fade. Deeper and deeper you sink into unconsciousness. Euphoria sets in as your panic begins to ease, in your mind you remember freedom, just a memory but not so long ago, is this death? Is this a good death? You take one last breath, and let go of
...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.
Picture this: you're having a nice weekend at the lake with your family, fishing, swimming, and having an all-around great time. But then you notice that your boat isn't running as well as it should, especially considering you just cleaned it and made sure everything was in perfect condition before leaving your house. Puzzled, you take your boat out of the water to notice that the hull and motor is covered in tiny clam-like creatures, making your pristine white boat look like something that was just drug out of the bottom of the lake. What are these animals that ruined your weekend of fun? They are zebra mussels, and are found in lakes, rivers, and other bodies of freshwater across the U.S. Normally found in Eastern Europe, the first group of this invasive species hitched a ride in the ballast tanks of ocean liners in the 1980s, and quickly spread. Regulations are in place to stop the spread, but removing them from places that have already been infested is tricky. Today we will talk about the damages zebra mussels cause, how this problem is managed, and what you can do to help.
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 close encounter and need of survival.It is important to know what they look like so it is easier to identify them and to know their special abilities so they will be easier to evade.Hammerhead sharks and bull sharks are very aggressive towards their prey and take over most oceans.These species are very important because if you want to study them for research,then you should know their normal personality traits for easier behavioral comparisons.
Underwater shark nets make us feel safer at the beach,but are we? That’s the question. Are we safe? There are lots of possibilities that the shark, with sharp like knife teeth, may outsmart us. Because of shark attacks we use nets, called shark nets. However, that doesn’t mean nets used in the past prevented shark attacks. These nets don’t only trap sharks they trap other sea creatures.
This image is what a majority of people believe to be the shark. They believe it to be the bloodthirsty sea monster that appears in countless works of literature and films, but science says otherwise. The classic picture painted by the minds of sailors returning from years at sea come from imagination and sharks’ violent methods of hunting and mating. Sharks fear humans as much as humans fear sharks, and most sharks, particularly the “man-eating” great whites, only bite humans because they mistake surfers for seals. In earlier times, the ocean was a source of mystery and adventur...
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.
It is not hard to think of the Great White Shark as one of the most feared animals
On average they weigh 4,000-7,000 pounds and grow approximately 16-20 feet long ( Great white sharks 1). < commentary needed>Great Whites are the apex predator of the ocean containing 300 serrated teeth and highly-developed senses to hunt prey. Sharks have a great senses of smell, the Great White can smell a drop of blood thousand of miles away. They’re hearing is very powerful , being able to hear the vibrations of prey distances of about 800 ft away and find the exact location through ‘ear stone’( Great white 3). A shark 's sense of hearing truly shows their uniqueness as an apex predator. In addition to great hearing they’re known to have great sight by being able to see up to 50ft away and transition into seeing in light and dark. Additionally sharks have a lateral line on their back that reaches from the front to the back tail, allowing
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.
Sharks appear to be very vicious creatures that will eat or kill anything in its path. People think that all sharks are harmful and deadly to humans. However, research shows that this statement is not true. Sharks can be trained and tamed. They are just like big, aquatic dogs. Only about 2 dozen types of sharks are potentially harmful to humans. Shark attacks are also much more uncommon than one may think. Despite their fearsome appearances, sharks are not as vicious as they look.
Watching a movie where hundreds of swimmers on a beach are in a complete panic because of shark attacks makes a person scared to swim in an ocean, lake, or even a pond. Not only movies, but also documentaries of shark attacks stress how dangerous sharks are. In reality, are sharks really that dangerous or is it how they are portrayed? Stephen R. Palumbi who is a Professor of Biology at Stanford University and also the Director at the Hopkins Marine Station at Stanford wrote an article about other animals living in the ocean that are more dangerous to humans than sharks. In fact, he has written books about creatures in the water such as The Death and Life of Monterey Bay, and The Evolution Explosion. In addition, his son Anthony R. Palumbi is a novelist and a science writer that has written for Atlantic and other publications (Princeton University Press 1). Together they co- authored an article titled “Forget Shark Week: They aren’t the only fish in the sea” that was published the Los Angeles Times.
The Great white sharks sense of smell is better than a human. A great white shark could smell a drop of blood from at least 500 miles away! Their eyesight is not so good but when a great white shark is being attacked they roll their eyes to the back of their heads so they can protect them. Sharks have an ear stone that senses vibration in the water from over 100 miles away. Sharks are great hunters.
Good morning Mrs Graham and class, my name is Molly Harris and my controversial law that I have chosen to amend is whaling. However before I talk I would like to show you a video. It is the least graphic video I found yet if you feel uncomfortable please look away.
One particularly interesting sea creature is the whale shark, formally known as Rhincondon typus it was first discovered in 1828 by Andrew Smith (Rowat 2012). This large fish is found globally in warm tropical oceans and prefers to stay within 200 meters of the ocean’s surface in waters ranging from 4.2 to 28.7 degrees Celsius (Stevens 2006). This creature can be found all across the globe in any warm tropical seas. Aggregations of whale sharks have been seen off the coast of Australia at times, although it is primarily a creature of solitude. Whale sharks are filter feeders that consume plankton as well as small fish and are harmless to humans. The whale shark is a species with a fascinating ecology, life history, behavior, anatomy
